Introduction

Uffington Castle, Berkshire. This subs tantial hill-fort was co nst ructed arou nd 700 BC, and encom passes an area of approximately nine acres . A white horse symbo l cut into the chalk hillside adjace nt to t he hillfort pre-dates the fort itself, and suggests that Uffi ngto n may have served as a site of bot h po litical and religious significance.

Before beginning any discussion of 'the forts of Celt ic Britain', it is important to try to define just what constituted a Celtic fort, and who th e Celts actually were. We also need to know when th ey bu ilt th e fortified struct ures whic h still dot the landscape of modern Britain - if ind eed th ey were respo nsible for such structures. Archaeologists and historian s are un ab le to defin e whethe r Britain tru ly was Celtic, who the Celts actua lly were, or whe the r many of their 'fo rts' were really desig ned as military enclos ures. Som e arch aeo logists even catego rize th e sto nebuil t brochs of north ern Scotland as catt le she ds; in trut h , th ey are more like medieval sto ne keeps. Identifying who the Celts were is someth ing of a histor ical minefield, the evidence bein g drawn from the acco unts of classical writers, th e surv iving archa eological remai ns, and traces of linguistic links which can still be found on th e 'Celtic fringe' of Ireland, Wales, Cornwall, Brittan y and th e Scottish Highl ands. Un fortunately, th ese three strands fail to provide all th e answers, and sometimes contradict each other. The first classical referen ces to th e Celts by Greek h istor ian s occur in the 6th centur y BC, when th e peop le called th e 'Keltoi' were iden tified as occupying the lands to the north of the Greek peninsula. The Keltoi raided int o Greece and Italy, and in 390 BC they even sacked Rom e. The Roman s subsequently paid more atte n tion to their neigh bour s, part icularly after th e former expanded into northern Italy and th e French Mediterran ean coast. They described th e peo ple th ey enco untered as the Celts (or Galli in Latin). Some historians, such as Posidon ius (whose works were passed on by later copyists), may even have lived amo ng the Celts wh ile learn ing what he could about th eir culture. In th e mid-1st century BC, Julius Caesa r provided a more detailed descripti on of th e Celts (or Gauls) of wha t is now France in his De Bel/1II11 Gallico (The Gallic War). He began with his now fam ou s acco unt of th e land he co nquered: All Ga ul is divided into th ree part s, o ne of wh ich th e Belgae in ha bit, th e Aquita ni ano ther, th ose who in th eir ow n language are called Celts, or in our lan guage Gau ls, the th ird. All th ese differ from each othe r in lan guag e, custo ms an d laws.

Unfor tunately neither Caesar, Strabo, nor an y other classical writer had mu ch to say of the Celts who lived in Britain. Instead we have to rely on linguistic or archaeological evidence. Elements of what was once a pan- European Celtic lang uage still survive on the 'Celtic fringe' of Europe, wher e Welsh , Irish and Scots Gaelic all share th e same linguis tic roo ts. It was th e 18th-century Welsh scho lar Edward Lh uyd who first iden tified thi s Celtic lin guistic tradition, and who first esta blishe d th e existence of a finite Celtic culture. Indeed it was Lh uyd wh o resurr ected th e word 'Ce ltic', which co inci ded with th e eme rging evidence produ ced through th e new science of archaeology. From th e mid-1 9th century onwards, archa eologists began to un earth artefacts th at were att ributed to th e Celts - as defined by Lhuyd. Two sites in particular came to be associated with particular ph ases of Celtic cultura l developmen t: the Late Bron ze Age site at Hallstatt in Austria, and th e Iron Age religious site at La Tene in Switzerland, whe re Celtic votive offerings were recove red from th e waters of Lake Neufcha tel. Subsequently both sites gave th eir nam e to cultura l ph ases into wh ich all material evide nce att ributed to th e Celts was placed. However, th is was not th e wh ole sto ry. As evide nce of th e earlier Hallstatt ph ase can be found in some part s of Euro pe and not in others, archa eologists presum ed th at th e Celtic sph ere of influence expanded during th e Iron Age to cover all of France, Spain, Britain , Ireland, Switzerland, Austria and part s of Italy and a swathe of Eastern Euro pean countries traversed by th e River Danube. However, recent archaeological evide nce ha s sho wn th at even dur ing th e Late Bron ze Age th e indige no us (and presumably non- Celtic) peoples of Britain ma intained cultura l an d com mercial links with th e Celtic peopl es on th e Euro pea n mainl an d. Wh ile artefacts help exp lain links between different region s in th e Celtic world, th ey do litt le to help us understand how th e indi gen ou s populat ion of Britain inte racted with th e Celtic inco me rs from th e Late Bron ze Age on wards. In other words, the division between th e Celts and th ose th at came before th em is somew hat blurr ed . The on ly clear archaeological evide nce we can find is th e rem ains of pre-Celtic and post-Celtic sett lemen ts, religiou s centres and defensiv e works. While in recent years archa eologists and historians have becom e mor e hesitant in defining exactly who or what th e Celts were, th ere is at least some agreeme n t on whe n th ey lived in Britain. The Celts were essentially an Iron Age culture, a term first devised by Dani sh an tiquarians to help th em catalogue the ir mu seum co llections . Today th e British Iron Age is used as shortha nd for th e period from aro und 700 BC (whe n the produ ct ion of iron first took place in Britain) until just after th e Rom an invasion of southe rn England in AD 43. Even th ese paramete rs are far from fixed : for exam ple, it is gene rally held th at in Scotland, where th e

Rom an pene t ratio n was limited , th e Iron Age co n tin ued un til the 5th cen tury AD. For th e purposes of th is book we will limi t the study of Celtic fortifications to an even briefer period - from aro und sao BC un til a few decad es afte r the first Rom an in vasion of Britain , c. AD 80, wh en most of main land Britain had fallen under Rom an co n trol. Wh ile th e Celtic period co n tin ued mu ch later in Scotland, Wales and Irelan d, the nature of 'Dark Age' Celtic fo rtificatio ns is a su bject wor th y o f ano the r study, and will th erefore rem ain outside th e bounda ries o f this book . Sim ilarly, the aut hor has avoi ded cove rage of Irelan d, a lan d with its ow n Celtic tale to tell, whic h is o nce again deserving of its own book. No part of the survivi ng ph ysical rem ains o f Iron Age Celtic Britain is more spectac ular that th e fortificatio ns that still dot th e British lan dscape, from th e great earthe n hill- fort s o f so ut hern Eng land (such as Maid en Castle) to th e im posing sto ne-built broch s of no rth ern Scotland . While none of th ese were stro ng enough to keep out a determined att ac k by th e Roman war ma chi ne, th ey still domi na ted th e landscape, and to th e pre-Roma n peopl e o f Celtic Britain th ey wo uld have represented th e ultim ate state me n t in politi cal, mi litary and social po wer. This book will provide a brief survey of th e typ es of fortificatio ns used, and will show how th ey develop ed ove r time and how th ey change d from region to region . It is also hoped th at , in some way, it will explain how th ese great fortifi cati ons were defended, in th eir role as th e last bastions of Celtic civilizatio n in Britain .

Types of fortified sites

This map of the promontory fort at Burghead . Moray was drawn up by th e 18th-century military surveyor General William Roy.Although the fort was associ ated with the Piers, it was almost ce rta inly built earlie r. during the Late Iron Age. Much of the fort was destroyed during the expansion of the town soon after Roy produced his drawing. (Society of Ant iquaries. London )

Altho ugh hill-forts and brochs are the most commonly found type of Celtic fortification in Brita in, ot her types of fortified sites ex isted in ta ndem wit h them . The scope of th is boo k precludes a study of th e less defensible of these, suc h as lake Villages and cran nogs, largely becau se th ese struc tures lacked any obv ious mean s of defen ce save th eir encircleme n t by water. Altho ugh th e lake Village at Glasto n bury, Som erset was su rro un ded by a wood en palisade, it was prob abl y not designed to keep in trude rs out but rather as a protecti ve barri er to prevent ch ildren and anim als fallin g into the sur roun ding lake. Sim ilarl y wh ile buildings built over th e wat er, such as Oakbank Cran nog in Scotland 's Loch Tay, ma y well have been defensible for a sho rt time, it lacked the protection to keep determ in ed attackers at bay. For the purposes of thi s study we sha ll conce n trate on th e Celtic sites th at appear to have been desig ned with defence in min d . Celtic fortifi cations come in a variety of types, altho ugh with th e possib le exception of broc hs they all share certain characteristics. Over th e years archa eologists have developed termin ology that he lps them classify the intricate systems of ditch es and banks th ey encoun ter. These are often augmented with more Wide ly understood fortification term s to help explain how th ese features were supposed to work. For exam ple, many arch aeologists use th e word s 'ban k' and 'ra m part' interchangeably, but to be more accurate th e fortification term 'ra m part' sho uld really on ly be appli ed to th e innerm ost bank surro unding th e fort's enclosure. If a fort is enclosed by a single circuit of bank and ditch, it is described as a 'univa llate' fort . More com plex fort ificati on s are described as 'bivallate' (if th ey have two such lines of defenc e), 'trivallate' (if th ey have three circuits of bank and dit ch ), and 'm ultivallate' (if th e fort is defended by more than three lines of defence). If th e banks are set close together th ey are described as 'com pact', whil e th e opposite are regarded as 'dispersed' . Given th e range of different types of fortificati ons , most fall into four general categories. The first are the pure hill-forts, whose defences are placed to make best use of th e terrain. The perim eter of the enclosure follows th e co nto urs of the hilltop on whic h the fort is built, and consequent ly th ese fortificatio ns are rarely circular or even regular. Instead th e lines bend in accordance with th e shape of th e hill. The result is an irregularly shaped defensive position, but one that makes best possib le use of the lie of the land. A variation on th is is th e headland or promontory forts found on rocky spurs of coastline wh ere th e site could be made defensible with relatively little work . In sites such as Burghead in Moray, Scotland, or Rame Head in Cornwall these fortification s close off th e landward side of a headland by mean s of a defen sive bank and ditch system similar to that found in hillfort s. The only difference is that on th e rem aining sides of th e defended position th e sea itself provides a natural barrier to attackers. It is wo rth noting that forts of thi s kind are not always found on th e coast. On rare occasion s wh ere the terrain provid es a similar

adva ntage far from the sea, such as at the confluence of two large rivers, a similar position could also be established. An example of this is th e Iron Age sett lement at Dyke Hills in Oxfordsh ire, where th e River Thame meets the River Thames near mo de rn-day Dorcheste r-on-Thames. There a bivallate defens ive line was created to pro tect th e sett lement, while the two rivers protected th e remaining three sides of the site. A variant on th e h ill-fort is what has unsat isfactorily been described as the plateau fort, or valley fort. These are similar to the more common hill-forts, but were buil t on sites th at possessed no defen sive adva ntages such as slopes or even rivers. Inst ead th ey had to rely on their own man -made defences to keep attac kers at bay. The on ly real adva ntage of this type of fortificat ion seems to be th at in ma ny cases th e enclosure inclu ded a natu ral spring, so tha t, unlike man y hillforts, th e defenders had access to water and thus in th eory could bett er with stand a siege. Ofte n these appea r to have been built in areas of goo d farml and, in valleys or on broad ridges wh ere no more obviously defensible feature was available. An exam ple of thi s type of early Iron Age fort is Rain sborough in Northa mptonsh ire, wh ich was excavated dur ing th e 1960 s. There th e fortification stoo d on th e edge of a plateau, whe re th e ground th en fell away gen tly int o th e Che rwell Valley below. It enclosed an area of some 2.5 hectares, and altho ugh its defen ces were uni vallat e, th e archaeologists un covered traces of an outer bank th at had been filled in at some stage during th e fort's occupa tion. The occupan ts may have come to regret th e siting of th eir fort : archaeologists also un covered evide nce th at th e gateway had been destroyed by fire, and a skeleto n was found amid th e burned ruins of a guardho use. The inference is of course th at the fort was attacked and captured probably at some point in th e 3rd cen tury BC Ano ther distin ct group of forts com prises th ose th at were clearly built as nondefensible enclosures, probably to house livestock or to provide a seasona l hom e for a farming comm unity. Sites of this kind were ofte n built on th e sides of a hill or in a flat area, and often invo lved m ultipl e enclosures encircling a central area. Wh ile not primarily designed as a defen sive position, th ese could serve as an emergency refuge in tim e of dan ger. Examples of forts of th is type include Lorde ns haws in Northumberland and Clovelly Dykes in Devon , and th ey are generally locat ed in either the north of Eng land, the south-west, or in th e western

Th e Iron Age hill-fo rt at Woden Law in the Scottish Bo rd ers was built in three phases, and in its final for m cons iste d of a doub le ram part and dit ch.The curving double bank in the foreg round has been ide ntified as a Rom an siegework, sugges ting that t he small hill-fort might have been besieged during Agricola's cam paign in southern Scotland ar oun d AD 8D-81 .

The Iro n Age hill-fort on Barry Hill. Angus on the edge of th e Scottish Highlands was built over two phases : the large oval bank of rubble th at rep res ents the lat er phase was built on top of an earlier ear thwork.A lesser outwork protected the southern and eastern approaches to th e fort . while a small area on th e no rth side may have se rved as an animal enclosure. (RCAHMS)

coastal fringe of Wales. Clovelly Dykes is a prime example, with a central compound of 1.2 hectares surrounded by an oval bank and ditch, whi ch in turn was ringed by another full bank and ditch, then two more low-banked enclosures, some of wh ich had associated ditches in front of th em. The site also boasted a large annex enclosure on its western side, pro tected by another ditch . In all the fortification encompassed an area of some 9.6 hectares. Th is co mp lex site was expanded during its period of occupancy, as it seems the outer enclos ures were added after the in nerm ost enclosure was bu ilt. Given the min or na ture of th e outer works it is probable th at th ese served as livestock enclos ures, wh ile th e inn er enclos ure hou sed a sma ll farming com m un ity or even a large farmstead . Even sma ller fortified enclosures have been fou nd, pa rtic ular ly in Scotland whe re th ese structures are kn own as ring forts or rath s. These sma ll enclosures were almos t always un ivallate, pro tected by a circular or near -circular ban k and dit ch syste m . In some cases th e en closure enco m passed a natural or artificial mou nd, but th ey could also be built on level ground, such as th e ring fort s found in Glen Lyon, wh ich may have been built as boundary markers or outpos ts, guarding the developed Iron Age comm uni ty of Loch Tay an d th e sum mer pastures in th e h ills between th e glen and th e loch . Othe r ring wor ks seem to h ave served to protect farm ho uses, a little like th e fortified farmhou ses foun d in med ieval Europe. Exam ples of th ese include Dan-y-Coed and Woods ide, both in Dyfed, Wales. What is unusual about these last two sites is th at they were stro ngly fortified, with a bivallate defen sive system, and both were approac hed along a pathway lin ed by more banks. It has been suggested th at thi s banked approac h served as a means of herding cattle to and from th e main enclosure. The im pression th at th ese were farming settle me nts rath er tha n villages is en hance d by archaeological evide nce of roundho uses lackin g central hearths - suggesting th e presen ce of farm buildings rath er th an dwellin g hou ses. Fina lly th ere are th e broch s, th e majestic sto ne towers foun d in n orthern Scotla nd . The re may well h ave been a cro ssover betw een th ese buildings an d th e sto ne -clad ring forts of cen tral Scotland or th e sto ne -built hill-f orts found in Wales. However, th ere is virtua lly n o evide n ce th at th e peopl e who built th ese structures had any assoc iation with th e builders of Celtic sites in th e rest of Britai n. Given the limited sco pe of this book we can on ly tou ch on thei r basic features and sugges t h ow th ey m ight have served th e peopl e wh o built th em . Arm it (2003) covers th e sub ject in co ns ide rable detail, an d is th orou ghl y recommended for th ose who want to explore this topi c further.

The h ill-forts of Celtic Britain , th e large earth-bu ilt structures th at can be found th rou gh out th e land, are mostly con centrated in two broad areas. The first of th ese areas forms an elongated trian gle running from th e island of Anglesey in Wales southwa rds th rou gh th e rest of Wales, beyond th e Welsh mountains, th en across th e River Severn in to mod ern-day Eng land . From th ere th e swathe runs southwards to th e sou th Devo n coas t, an d south -east and east to th e head wat ers of th e River Th am es, co ntin uing to th e Kentish shore. The seco nd large band of hill- forts runs th rou gh th e easte rn lowlands of Scotland, from th e Beaul y Firth near Invern ess round th e coast to Aberdee n, th en south th rou gh Angus and Fife to th e Loth ians . From th ere it th en runs in a south-easte rly direction toward s the Solway Firth, wh ich marks the Eng lish border. Hill-forts did exist outside

these areas, but not in such great num bers. Within these genera l bands the size and sty le of the forts varied co nsiderably. In very broad ter ms the forts found in Wales, Scotland and the north of England tend to be smaller and more numerous than the hill-for ts found in the south of England . There are of course exceptio ns: Traprain Law and Tre'r Ceiri were as impressively large as many found further south. These fortifications were built over a span of seve ral centuries, and not all remained in continuous occupation throughout the Iron Age. Th e fact that certain areas of mainland Britain seem almost devoid of hill -for ts while others have a profusion has never been fully exp lained, but may well represen t so me form of socia l difference betwee n th e in habi tants . Some archaeologists have argued th at man y of th ese forts represent territorial divisions, whe re th e forts represen t poli tica l sta te me nts of land owners hi p an d bo un da ries as mu ch as fortificat ions in thei r ow n right - akin to th e feuda l castles of th e medi eval period . Certain ly so me of th ese forts might well have served as political cen tres of po wer; th e proximity of man y to lat er Rom an provin cial cen tres is often used to suppo rt this argument. Un fortu na te ly we kn ow all too littl e abo ut th e distribution and political organizati on of Britain 's Iro n Age populati on, so th e terr itor ial importance of hill -fort s remains a matter of speculation . The sto ne-bu ilt brochs are concentrated in th e north of Scot land, parti cu larly in th e northern isles of Orkn ey and She tlan d, and th e Western Isles. However, isolated exa mples can also be found as far south as th e Scottish Bord ers. Th eir construction is unique: th e largest surviving structures look more like giant kiln s tha n forti fications.

Due to limit ation s of space, any descripti on of th ese two fortifi cation types ha s to remai n fairly general; however, each n eeds to be dea lt with separate ly as, in all but thei r purpose, hill -for ts and broc hs have litt le or nothing in co m mo n. A related for m of Iron Age fortificatio n is th e 'dun ', wh ich in essence repr esents a sma ller version of a broch - more like a sma ll sto ne enclosure th an a tower. Wh ile th ese may have been used as nothing more th an fortified hou ses or farm comp lexes, some may well have served as im portant forti fied sites in th eir own right.

Design and construct ion Toda y, Celtic fortificati on s, parti cularl y hill-forts , are readily identifiable by th e remains of th eir ramparts and ditches - a stil l formidable system of fieldworks which serve as visible reminders of an Iron Age past in Britain. The fact that they can still be seen is a testi mony to the skill with wh ich these fortificatio ns were sited and bu ilt, and to th e lon gevity o f the materials th eir build ers used . These fort s were built using sto ne, earth and timber, and all but th e last of th ese ma terials have weathered the centuries. Altho ugh th e era was known as th e Iron Age, very littl e ferrous ma terial was used in fort constructio n - the exception being th e odd gate hin ge or bracke t. Sim ilarly mortar was a post-Roman build ing ma terial, and the Celts of Britain used dry-ston e construction techniqu es in th eir forti ficatio ns. This was not necessarily a drawback. The fact that the Broch of Mou sa in Shetland is still standing after two millennia proves th at th ese structures were bu ilt to last.

Hill-forts: form and function

The small hill-fort of Caburn, Sussex was built during the early Iron Age. although archaeologists now believe its defences were strengthened around the mid-I st centu ry AD. poss ibly in res po nse t o t he Ro man invasion of Brita in.The site was abandoned soon afterwards.

The ter m hill -fort is defined as a fortified enclosure , designed to take advantage of a h ill or rise for its defensive advan tage . The fortificatio n could consis t of one or more circular or part-circular ea rt he n or even sto ne ramparts, built to fo llow th e con to urs of th e hill th e fort was sited on. In man y cases th ese rampart s are often associated with atte ndan t externa l dit ch es. Th e structures date from th e Late Bron ze Age and th e Iron Age. Beyond th is rathe r gene ral definition , th e variation in types an d size of hillforts is con siderable, as are th e dates given by archaeo logists for th e occupa tion. These fortificatio ns varied from what amo unted to little more th an a sma ll cattle enclos ure to a fort big eno ugh to acco mmodate a reason ably sized town . The larger settleme n t h ill-fort s - th e type Ju lius Caesar called oppida whe n he enco untered th em in Gaul - were clearly of great imp ortance to th e people wh o bui lt them , and fun ction ed as muc h as a statemen t of regiona l power as a place of refuge in time of conflict. Few British sites mat ched th e scale of th ese Gallic forts, alth ough hill-forts like Maiden Castle came close. Some hill-forts fun ction ed as perm an ent settleme nts whilst othe rs appear on ly to have been occup ied in tim e of dan ger, during a particular season, or for some specia l even t. Some show little or no evidence of milit ary use, and sho uld th erefore be seen more as enclosures to pen in dom estic ani mals rath er than as fortified stro ng points. The only broad definition of use is that the hill-forts were built to prot ect settlem ents or livestock from atta ck. Inevitabl y th ere is some debate over how and why th ese hill-fort s were used, and whe n. Most appear to have been used for at least tem porary habitat ion or as fortified military enca mpme nts during th e th ree centuries before th e Rom an conq uest of Britain, whic h constitute th e Midd le and Late Iron Age, and all but a few fell int o disuse after th e Rom an occupatio n. However, a few were re-occupied in th e 5th century AD after th e Rom an s left, and a few were even used as field fortification s by th e Ang lo-Saxons during th e Viking incursion s thr ee centuries later. In areas such as northe rn Scotland and Wales, whe re th e Rom an influen ce was less pro no unced , hill-fort s tended to remain in use for longer. Inevitably th ese multip le periods of occupation and d ifferent types of use have tended to mask th e real purp ose behind th ese fortified enclosures, and to enco urage vigorous excha nges between

archaeologists. The easiest way to appro ach th is difficult subject is by expanding th is broad definition of th e archetypa l h ill-fort, showing how it might have fun ction ed, and then looking at specific exam ples to see how the hill-fort changed over time, and how different fortified sites were used in different ways. Looking at a hill-fort from outside its perim eter it is easy to forget th at its most imp ortant feature was not th e serried ranks of ban ks and ditch es protect ing its circumference, but th e area inside the earthworks that it was sup posed to protect. In the case of the majorit y of hill-forts th e archaeological evide nce of what once stood in a fort's int erior is slight - at best th e traces of a few earthe n tracks, semi-perma ne nt timber huts, sto ne-clad wells or refuse pits. Most of th ese features are on ly visible thro ugh archaeological excavation, and most h ill-for t digs have revealed th e shadowy traces of th ese signs of habit ation , suggesting th at the majorit y of hill-forts served as dwellin g sites - wh ether design ed as perm an ent sett lemen ts or as temporary refuges. Whil e most sites in southe rn Eng land were built on relatively low-lyin g hills, othe rs in Scotland and Wales were probabl y too high up to remain in use through out th e year. In these cases th ese h igh er hill-fort s were probably used during th e summe r, wh en livestock was moved to hillside pastur es. Hill-forts were clearly built to serve a local agrar ian com muni ty rather than a military garrison, and so th ey were almos t always locat ed wh ere goo d farml and was with in easy reach. The peop le who built th em were farme rs rath er than me rchants or trad ers, and whil e th ere is archaeological evide nce of metal working and other in dustry, we can find littl e archaeological or historical evidence of hill-forts serving as trad in g cen tres or even th e sites of travellin g 'fairs'. All th e evidence we have comes from the presen ce of ceram ic or metal artefacts wh ose place of origin lay far beyond th e boundaries of th e com m un ity that built th e fort in whi ch th e objects were found. Similarly we can on ly guess at th e admin istrative or region al imp ort an ce of most hill-fort s, as th e dearth of written evidence preclud es anythi ng more th an speculation.

At Caburn, Sussex there is evide nce that a seco nd ram part and a broad but shallow ditch were added to the earlie r defens ive works in res ponse to the Roman threat.Traces of both phases of construction can be seen here. (Co urt esy of Steve Danes)

Build ing the hill-forts Although archaeo logy can rarely tell us exactly wh y a hil l-fort was built in a particular location , or even wh o built it, it can usually reveal someth ing of th e way th e fort was built, an d how it developed over tim e. In addition we can draw on other archaeo logical evidence to improve our understanding of th e peop le

who in habited Britain during th e Late Bronze Age and the Iron Age, and to show what too ls and techniques th ey could app ly to a major building project such as this . The site of th e fort seem ed to be crucia l. In some places hill-forts were built within sigh t of each other, which has led to the theory that they co nstituted an interconnected network of defen ces - akin to an Iron Age Magino t Line. While this no tion has largely been discredi ted, it does appear that forts were bu ilt to dominate the im mediate hin terland, usually on a hill over look ing an arable and po pulous valley. Wh atever th e reason for construction , th ese Iron Age 'e ngineers' certai nly knew how to ta ke adva ntage of the terrain. Almos t wit ho ut exce ption Britis h Celtic h ill-forts were sited to make the best possible use of th e conto urs of th e hill on wh ich they were built. In other word s th e steepness of th e slope on one or more sides of the position , th e proximity of rivers and stream s, or th e visibility of any approach ing force were all facto rs used to decide whe re th e fort sho uld be bu ilt. The followi ng acco unt of th e building process is gleaned from the archae ological inves tigatio n of Ladle Hill fort, Ham psh ire, whic h was excava ted by Professor Piggott in 1931. What was unusual about the site was th at it was never com pleted, and so traces of several ph ases of building could be identifi ed. Abo ut a th ird of the 3.3-hec ta re (8-acre) site was already delin eated by an existi ng bou ndary ditc h before th e const ruction work began, and this feature was utilized by th e bu ilders to help them . The rest of th e circumfe rence was de linea ted by a series of ditch es, whe re th e excavated earth was piled int o mounds on th e inner side of th e ditch . Piggott detected th e hand of at least 12 digging tea ms at work, but the project ended before th e va rious team s could link th eir ditch es together. In effect, Lad le Hill is a perfect exa m ple of an Iron Age buil ding site . The first stage mus t have been to mark out th e near-circular course of the ditch. We know enough about Celtic society to imagi ne that some form of druidic religiou s ceremo ny would have been involved . In at least one hill-fort th e rem ains of wh at might have been a sacrificial victim hav e been found, suggesting th at th e British Celts took th e idea of hon ouring a deit y very seriously. However, all our di rect acco unts of drui dic practices come from non -Celtic or post-Roma n Celtic sources, and the exac t nature of th ese ceremonies is very mu ch a matt er of speculation. After th e ceremo nies came th e hard labour - diggin g th e dit ch . As already noted, several team s began work at the same time in different part s of the perime te r. At Ladle Hill thi s first dit ch was never co m pleted, but th e sections th at were dug were of a fairly uniform size, approx ima te ly 1.Sm deep and 3m wide. Rather than simply dumpi ng the soil on the inner face of the ditch to form th e ram part, the teams carried the ir soil a few yards inside th e fort, creating a series of temporary soil dumps. This allowed th e walls to be built wit h some care: a base and inner revetm ent of large cha lk boulders was created, and th e rest of th e soil was used as infill. A timber framework would have been constructed - essentially a wooden cage within whic h th e rubble and soil would have been poured . The slope on the outer side of the bank would have been more substantial than on the inn er face, so a stone or timber revetment wou ld have been essen tial to keep th e soil in place. Th is inner revetm ent was substan tial, as it was also design ed to rein force th e bank and prevent it from collapsing . This was not an easy task, given th e simple tools availab le, and the co nstructio n of a revetment of th is kind represented a feat of engineering that belied the idea tha t the builders lacked engineering skills. Amazing ly, in sites where evidence of th is timber framewor k

has survived, there is no sign that nails were used; the structure was either slotted together, or tied into place. It also involved a lot of work. Evidently the idea of carrying the same load of soil twice was clearly considered a necessary sacrifice in order that th e finished wall cou ld be built in a methodical manner. At Ladle Hill the eastern portion of th e rampart was built to what mu st have been its full planned height of aro und four metres, with a substa ntial chalk revetm ent bracin g it. The bank was approximately seven metres wide, tapering on its outside face to a narrower platform of ap prox ima te ly one metre. A simi lar sma ller section of rampart was completed on the fort's western side, but th e two sections rem ain ed uncon nected. It is almost as if the num ber of skilled wallbuilders was sma ller tha n th e num ber of men requ ired to dig and tran sport th e soil - which was almos t certa inly th e case. This suggests th e presen ce of experienced supervisors. Lad le Hill is not th e o n ly fort whe re th e work remained unfinished . In several othe r cases improvements to existing fortifi cati ons show signs of having neve r been co m pleted, particularly in th e south of Englan d . As many of these feat ures hav e been dat ed to around th e mid-l st cen tury AD, th ese ma y well have repre sented eme rgency co ns truct ion pro grammes begun as a response to the Rom an in vasion of Britain. The fact th at th ey were un finish ed ma y be explained by eithe r th e speed of th e Roman adva nce th rou gh th e region, o r by the dive rsio n o f the labour force into mob ile armies, cha rged wit h co n testing the invas ion . It is in te resti ng th at in most of th ese cases th e work also appea rs to have been undert aken by seve ral team s wo rking sim ultaneously. The tim e taken to build a fort in thi s mann er wou ld obvio usly depend up on th e size and availability of th e workforce, or th e size of a perceived threat to th e community that undertook th e work . In th e case of larger hill -forts such as Maiden Castle co nstruction of th e perimeter defences could well have tak en several years, part icularly as th e workforce alm ost certainly had to fit th e work in betw een the seaso n al dem ands imposed by arable farming during th e Iron Age. Once the rampart and dit ch had been completed, th e fort-builders would begin work on th e palisade, which would surmo unt th e bank. In most cases thi s involved th e sin king of a line of timb er posts abo ut one met re apart aro un d th e outer edge of th e ram part, th en link ing th ese with cross-braces . The structure would the n be co m pleted by filling th e gaps between th e posts with large stakes, the reby creating a solid palisade. We sha ll look int o th e nature of th ese timber defences in more detail , but at Ladl e Hill th e wooden perim eter would have been co m pleted by th e building of one or more gateways. As th e fort was never fin ished and its perimeter never completely dug, we cannot be sure how many gates were planned to be in corporated into th e Ladle Hill defen ces. However, if we look at th e evide nce from othe r forts such as Dan ebury in Hampshir e we can imagine how th ese would have looked . Stout posts would have been du g between two in wardl y turning spurs of rampart , and th e palisade would have run up to these gate posts. For easier o pen ing th e woo de n gate would have been built in two parts; th ese were secure d to th e post s using iron fittin gs. The co m pleted structure would have involved a substa ntial ditch - no dou bt dee per and possibly wide r th an th e preliminary ditch th at was du g before wo rk sto pped on th e site. In fort s of similar size th e dit ch could be up to three or four metres deep . From th ere a steep glacis would rise up seven metres toward s a wooden palisade, su pported and braced using stout timber posts and beam s. A narrow wall-wa lk behind th e palisade would hav e provid ed a fighting platform, an d from th ere th e bank would have fallen sharply away toward s th e int erior of the for t. A sto ne revetm ent would have prevented thi s bank from bein g eroded through use. We can no t tell if a more elabo rate structure was plan ned at Ladle

LEFT The defences of a hill-fort: Old Oswestry, 50 Be This impressive hill-fort encloses an area of 5.3 hectares ( 13 acres) . and was the subject of an excavation during the late 1930s. It appears the fort was built in th ree phases fro m aro und 600 BC unt il the ar rival of the Romans in the mid- Ist centu ry AD. During each phase an add itional bank and ditch was added to the st ructu re . although the final (o ute rmost) phase of construction undertaken arou nd ISO BC was by far the most extensive. During this last phase the gate house was strengthened w ith the add ition of a series of banked enclosures o r anne xes on e ither side

of it. Most prob ably th ese served as miniature fortified pos itions from wh ich the defende rs co uld fire upo n any attac ker who attempted to rea ch th e gateway via t he walkway bridge. Li ke most hill-forts , the principal line of defe nce was the innermost bank o r ram part - the oute r banks and ditch es would have se rved to slow down an attacker. o r even to kee p him beyo nd slingsho t range of the inner defe nces .The we ak po int of any hill-fort was its wooden gateway, so th is was where the defende rs co ncentrated the ir efforts , developing 'killing groun ds' which covered all approa ches to the vulne rable gateway.

Hill, whe re defensive wo rks outside th e gateway or additiona l countersca rp ditches would ha ve been add ed . Wha t we can calculate is th e time taken for the bu ilde rs to com plete th e structure th ey began wor k on . Had it been co m pleted, th e hill -fort at Ladle Hill would ha ve in volved th e tra ns portation of some 11,000m 3 of soil, boulder and rubbl e du g from th e dit ch ; in additio n, if suitable stones could not be found th ese wou ld have had to be mo ved to the site from elsewhere. On ce th e mat erial from the dit ch had been graded and sorted it would have had to be moved again , thi s tim e to th e site of the ram part. If we appl y the construction yardstick where a man can dig and transport one cubic metr e of soil per day (given th e sim ple tools ava ilable), and assuming th at half as much tim e again wou ld be needed for th e subsequent retransportation of th e soil at th e rampart site, thi s means th e diggin g and soil mo ving alo ne would have taken aro und 16,500 man days of work. Includ ed in th is total is the time taken to build th e revetm ent. Given th e perimeter of th e ban k would have been about 680m long, we can assume th e build ers would have nee ded about 1,000 sma ll trees to prov ide th e posts, braces and stakes needed to build the palisade and gateway. We can add another 500 man days for th is work , giving a rough tot al of 17,000 man days. Archa eologists have de termin ed that for each hectare enclosed withi n a fort th e defen ces could hou se and pro tect approximately 60 people. Tha t gives us a wor kforce of 200, a tot al th at would include wome n and children (who would have been used to tran sport th e soil in baskets). If we redu ce th e wo rkforce by a qu art er to include th e lesser contribution of th e elde rly and th e ch ild ren, we are left with a total pro ject time of approximately 112 days, or rou ghl y four months.

The Scottish Border hill-fort of W o den Law. Roxburgh originally consisted of a single stone bank and ditch. sited on the edge of a preci pito us slope. During t he 1st century AD an additional pe rimeter of two banks and correspo nding ditc hes were added to the fo rt ificat ion .Archaeologists are st ill deb at ing whe t her th e Rom an siegeworks locat ed clo se to the fo rt we re use d in anger. or rath er se rved as a tr aining groun d. (RCA HMS)

The same equation can be exte nded to incl ude othe r sim ilar hill-forts, includ ing Maide n Castle. The on ly differen ce would have bee n that in severa l of th ese sites the defences were built in severa l phases, ofte n a cen tury or more apart. These earlier works were ofte n inco rporated int o th e new design , wh ich reduced th e amoun t of wor k involved. However, in its fina l phase Maiden Castle was pro tected by no fewer th an three ban ks and a countersca rp bank, and three ditch es. In additio n the gate ho use defences were significan tly grander th an those th at would have bee n built at Ladle Hill. The hill-fort historian A.H.A. Hogg estima ted th at in time of peace th e defen ces of Maiden Castle could have bee n im proved from one building phase to ano ther in a period of approx ima te ly five to seven months. As thi s would have involved an un acceptable degree of disru pti on to th e farm ing life of th e com m un ity, he argues that th e wo rk would have been spread out over two or even th ree seasons. In many ways Ladle Castle was the ideal size - a sma ller hill-fort would almos t certain ly have served a sma ller population, wh ich meant th e work invo lved would have taken lon ger. Here again th e wor k would have im posed on th e agrar ian calenda r, and so would prob ably have been undertaken ove r at least two yea rs.

The design of brochs

20

Un like th e h ill-fort s found elsewhe re in Britain , th e broch s of north ern Scotland were defensive wor ks design ed to pro tect a relatively sma ll number of people. The term 'broc h' is gene rally used to refer to a free-sta nding, round, sto ne -built tower, altho ugh severa l of th ese may also have been built as a centrepiece of a forti fied sett leme n t. Their or igins rem ain someth ing of a mystery. One early theory was th at th ey were built by an influ x of newcomers - refugees from th e Rom an invas ion of Britai n. However, since no sim ilar structures existed fur ther south, th is notion is easy to disprove. Also, most broc hs have bee n dated to betwee n sao and 200 BC, although th ey rem ain ed in co nti nuo us use un til th e Rom an perio d. The best-surviv ing broc h struc ture at Mousa in She tland was built aro und AD 100, and rema ined in use for approxima tely two cen turies. The dat es app ly to other sites too, as at some da te after AD 100 the majority of broc hs appear to have fallen int o disre pair. In structures such as th e Brach of Gurness, where the tower was surro unded by a fortified settlement, th e Vi llage itself seems to have been aba ndo ned, and the sto ne re-used to construct farm buildi ngs close to th e old site .

The com mu nities served by th ese fortifi cati on s mu st have been sma ll compared to th e Iron Age com mun ities who built hill-fort s, but th en th e two types of fort ification do not bear close comparison. Given th e correlatio n between hill-fort size and th e estimated number of peopl e wh o lived in or beneath it, on ly the smallest h ill-fort s can be compa red in scale to th ese broch s. Both involved a co nsiderable amo unt of effort for th e sma ll agrarian com m un ity who built th em , particularly whe n some hill-fort s or broch s seem to have been little more th an fortified farms, serving at most one or two extended famili es. It has th erefore been suggested th at in places like Orkney or She tland, wh ere these broch structures are common, neighbour in g com m un ities pooled th eir efforts and helped out in th e construction of each othe r's tower - similar to th e com muna l barn -building tradition of th e Amish co mm un ity in th e Un ited States. A typical bro ch was built using dr y-ston e walling, and was approx ima tely 20m in diam eter. The broch at Mou sa sta nds some 13m high , altho ugh othe rs migh t well have been lower structures - no more th an five metres in height. The walls were doubl e-skinned, with a cavity between th em wide eno ugh to fit a staircase th at wo und its way up to th e to p of th e tower. In most large brochs th e walls are approx imately three metres thick. The structure was en tered th rou gh a small, low doorw ay; th ese were ofte n flanked by guard cha mbers to improve th e secur ity of th e fortificat ion . The in ter ior was almos t certain ly divided into floors, each level bein g accessed fro m th e sta irway and its atten da nt galleries. In broc hs such as Gurness, Midhowe and Mousa th e lower floor co nta ined a sto ne-lined well and food storage pit s, whi ch meant th e defenders could withsta nd a len gth y siege. Archaeo logica l evidence suggests th at th e who le struct ure was cap ped by a con ical pit ched roo f of th at ch or turf, with timber or even wha lebo ne suppo rts. The same dry-ston e walling techniques have been practised in the north of Scotland ever since, as exemp lified by old cro fts and farm boundary walls. Broch s always seem to have been buil t in easily defensible locati ons, but they wou ld also h ave had to be co ns tructed close to th e ara ble land worked by

In man y cases th e struc tures were built close to th e sea: Gurness and Midhowe were both built on th e Orkney seashore, separated fro m each ot he r by th e wat ers of Eyn ha llow Sou nd. The Broc h of Gurness is parti cul arl y impressive, becau se a sma ll sett leme n t of at least six sets of hou ses was built ben eath th e tower itself. Each was ente red fro m a main passageway that led th rou gh th e village to th e broch . Some of th ese buildings were entered from sma ll co ur tya rds, flanked by sto rage she ds. Th e result resembled a sto ne -built warren . Surro und ing th e village was a substan tial sto ne wall at least two met res high , which may h ave been surmo un ted by a sto ne walkway and parap et. Th e who le co m plex was en te red through a double gate, reach ed by a sto ne- lined approach that span ne d a dit ch running around th e landward s side of th e village . Beyond this a series of two banks and dit ch es co m pleted wha t mu st have appeared a most formidable site. The neighbouring broch of Midh owe was smaller, with a less develop ed defen sive syste m surro unding th e tower and sett leme n t. Structures such as th ese suggested th at th e society wh o built th em was one under threat , eithe r from n eighbouring co m mun ities or more likely from outsiders. Were th ey built as a reaction to a wave of arme d Celtic settlers from th e south, or were th ey sym bo ls of com m uni ty power in an othe rwise stable society? So far arch aeo logists have failed to provid e a clear answer. Wh oever built th em and for wha teve r reason , th ey remain as pot ent reminders of th e Iron Age com m un ities wh o felt th e need to defend th em selves in such a dramat ic fashi on.

Although every hill-fort is different, the easiest way to understand what th ey looked like and how they func tioned is to conduct a tour of one particular site as it looked in its heyday. Hill-forts remained in use for long periods, often several cen turies, so thi s will do little to exp lain th e deve lopment of the site, altho ugh it will offer a snaps hot of what it would have looked like at one part icular stage of its developmen t, just before it fell into disuse. For the pur poses of th is exercise th e sma ll h ill-fort at Dane bury in Hampsh ire offers one of th e best veh icles; at just 5.3 hectares it is sma ll eno ugh to act as a mod el for other larger and more co m plex sites. It has also been com prehe nsively excava ted, so we know a lot about th e site com pared with othe r similar fort s. The first hill-fort at Danebury was built around th e mid- 6th century BC, and altho ugh changes were mad e to th e fortifications over th e cen turies, th e h ill-fort remained in use unt il aro und 100 Be. At tha t tim e its occupa tion came to an abrupt and possibly blood y end. Whil e it is not part of thi s exercise to provide a detail ed account of th e changes th e hill-fort underwent durin g thi s period , a brief outline will help our understanding of th e site. Professor Barr y Cun liffe wh o directed its excavation in th e 1970s divided the development of Danebury into four ph ases, th e last of wh ich in volved th e use of th e fort in th e Sub-Rom an Period . Phase 3 represents how th e fort would have looked just before its dram atic end, and th is is th e one we sha ll focus on here. The fort sat on a sma ll chalky hilltop above th e River Test, 143m above sea level, a few miles to th e east of th e modern town of Winch ester. As th e rolling

do wn land surrounding the fort was not part icularly high, the fort would have been visible for some distance. On a clear day th e hill-for t of Beacon Hi ll can be seen to the north , whil e to the west th e aspect is of the open countryside of Salisbury Plain . The landscape sur rounding it would have been open, although extensive wood land lay to the south . The River Test provided water for catt le grazing , while a spring half a mile from the hilltop prov ided water for the sett leme nt it enclosed. In fact Cun liffe and his team have shown that during the Iron Age Danebury was surro unded by field systems, which date from between SSO an d 100 BC - ma king them contem porary with th e fort. The presen ce of Neolithic barrows in th e same area suggests th at Danebury was already an im por tan t location for th e local populatio n long before the hill-fort was buil t. A chalk road ran eastwa rds from th e main en trance towards a ford ove r th e River Test (where th ere was a profusion of field boundaries), wh ile a sma ller track circled the outer ditch from the main gate until it reached th e most southe rly part of the fort; at thi s point th e track th en headed south alon g th e rise wh ich led to Wallop Brook, ano the r heavily cultivated area. Approach ing th e fort from th e river, th e most obvious feature of th e fortification would be its ram part, a circular cha lk ban k th at stoo d about five metres above th e level of th e hillside. It was roughly trian gular in section, and was surmounted by a sma ll wooden palisade. The who le ban k was approx imately eight metres wide at its base, altho ugh it narrowed to acco m mo date a one-metrewide walkway set at th e rear of th e palisade itself. Imm ediately in front of th e ram part lay th e 'V-sha ped' ditch, four met res deep at its centre, and climbing slightly more acutely on its inne r face. The dit ch itself had been used to qu arry stones and chalk rubbl e to use in the co nstruction or heightening of th e rampart behind it, so it was substa ntial, measuring approx imately 10m across. In front of the ditch ran a berm or counterscarp bank, a rounded feature that, at two metres high, would hide th e dit ch from any attac ker, but would be overloo ked by defenders standing on th e rampart . The defen ces were not th e same all th e way aroun d th e circumference of th e fort. The ramparts on th e southe rn side of th e fort

The early developm ent of a hill-fort: Oanebury, 120 BC As a hill-fort, Danebury in Hampshire is typica l of many similar Iro n Age fortifications that lie scattered across southern Britain. However, unlike most others the site was t horoug hly excavated over a period of 20 years. As a resul t we now know more about how the hill-fort of Danebu ry evolved and what it looked like than most con tem porary fortified sites in Britain.The inset A shows a plan of th e earlier fort on the site, while the main illust ration shows th e hill-fort at the height of its RIGHT

development, befo re its sudden abandonment around 120 Be. Sho rtly after th is date the entrance on the south-western corner of the defences (B) was sealed off, leaving only one heavily fortified gateway on the fort's north-east corner (C) .The three sections of ramparts (0) show the way the fort deve loped over the centuries: the simpler defensive works of the site were improved during the Late Iron Age, while the ramparts themselves were progressively heightened and strengthened over the fort's period of o ccupation, from around 500 Be onwards.

Visitors would approach th e easte rn en trance to th e fort und er th e gaze of sentinels on th e ramparts , wh ere th e guards co uld easily close th e large wood en gates at sh ort notice if required, or drive intruders away with a hail of slings ho ts. The chalky approach road was nine metr es wide - eno ugh for two chariots to eme rge from th e fort side by side . The gate itself was a co m plicated affair, with two sections of outworks lyin g in front of th e gateway. Even before a visitor reach ed th e entrance an outlyin g dit ch had to be crossed, a wide but shallow tren ch that encircled th e wh ole hill -fort. Once past thi s obstacle th e visitor wou ld be faced with a series of small banks - essentially th e coun terscarp of th e main dit ch th at surrounded th e fort. These projected out to flank th e path, a litt le like th e claws of an insect. However, th e ditch ended at th e main gate itself, so th ese spurs form ed what is best described as a semi-circular oute r enclosure of th e fort (see page 27). Th e excava tions revea led that the gap betw een th e jaws of th e bank was sealed by an oute r gate way, th e exac t nature of whi ch is still uncl ear. Inside this enclosure two second section s of bank pro vid ed a furth er o bstacle befor e th e gatehous e was reached, protecting th e flank s of th e en clos ure. Where th e road cross ed the inner rampart th e banks turned outwards for 20-30m, creatin g a funn el through which an y visitor would have had to pass. This is wh ere the main gateway stood , a stru cture that was about six metres wid e, its approac h cove red by the proj ecting hornwork s of th e ram parts. It was

Th ere is evide nce th at some form of tow er or gallery structu re stoo d ove r th e gateway, probably linking th e two en ds of th e in ne r rampart s to form a co ntinuo us band of defe nces . A visitor wo uld have had to pass under th is struct ure to en ter th e fort itself. Once th rough the defe nces the wide cha lky road wo uld lead off in to th e interior of the fort, narrowing as it wen t un til it reached th e far side of th e enclosure. Other smaller roads forked off from th is ma in th orou ghfare like branches from a tree, two to the left and th ree to th e right. The roads to th e left were flanked by rows of square-shaped gra naries , probably raised off the gro und slightly on nine posts - three on each face and one supporti ng the centre of the structure. Each side of the building was approximately six metres across, alt ho ugh a few smaller, two me tre -wide, four-post grana ries or hayrick platfo rms lay scattered between th e larger buildings. Almost certai n ly each structure contained baskets or cera mic jars filled with wheat, oa ts or barley. To the righ t th e visitor would have seen th e main sett leme nt area of Dane bu ry, with a seeming ly irregular scatte ring of th atch ed roundho uses th at extended as far as the northern side of th e ea rthwor ks. The last fork in th e road led off towards a sh rine or temple structu re, built in what was rough ly th e cen tre o f th e who le enclosure. It was a squa re structure, approxi ma tely th e same size as th e nine-post grana ry build ings, but of more solid construction, with its walls set int o the ground. Three sma ller sh rines lay a few yards down the path towards the fork in the road , a larger one on the left of the pat h and two smaller ones to the right. All three were square, the largest being just under three me tres across , and th e entrances of all three st ruct ures faced the visitor as he approached the main temple 10m behind t he m on the pa t h. Althoug h archaeology can not defini tely say what was he ld in th ese shri nes, we know from

other evidence that th e Celtic peopl e who lived in Dane bury wo uld h ave worsh ipped a ran ge of deiti es, an d surro unded images o f th eir gods with votive offerings of food , dr ink or even scraps of cloth . Th e impo rtance of th ese structures wou ld have been em phasi zed by th eir cen tral position with in th e Dan ebu ry enclos ure . The one thing missin g from th e picture created by th e arc haeology of th e site is the im pression a visitor would have had of the peopl e who lived th ere. At its he igh t Daneb ury had a populati on of between 300 and 500 peo ple, as well as their do mes tic anima ls and pets. Chic kens would have scratc hed aro und th e feet of any visitor, whil e th e sme ll of an ima ls held in wicker enclosures next to the roundho uses would have been pervasive. San ita tion was largely unkn own , and hu ma n waste was sim ply dep osited in sma ll pit s th en loosely cove red ove r. From ot he r sources we kn ow wha t th ese peo ple would have looked like, and the appearance of th e Celts of th e Late Iron Age has been cove red in other Osprey books (see Men -at -Arms 158, Rom e's Enem ies (2): Gallic and British Celts). However, th e gene ral appea rance would have been of a fairly wealthy ru ral economy, and a com m un ity th at en joyed both a stable po litical structure and one wh ich could easily prov ide for th e welfare of its own people. Far from being a primitive sett leme n t, Dan ebury would have been a well-organ ized farming co m mun ity, whose inh abit ants en joyed a reason ably h igh sta ndard of livin g, and whose safety was assure d by th e impressive defe ns ive works tha t protected their village.

The living site Having examined the regional spread of these fortified sites in Iron Age Britain, and looked at the varieties of fortified enclosures built by th e Celts or their predecessors, we sha ll now look at how these fortifications were used by th e people who buil t th em , and how well they served as defensive positions in time of dan ger. Hill-fort s were not mere fortifications . In most cases th ey also served as a place of ha bitat ion for th e com m un ity who bu ilt th em . The defen sive qualities of th e fort might n ot be tested for decades or even cen turies at a time, altho ugh th e mere presen ce of th e defen ces would have acted as a deterrent to pot entially hostile neighbour s. Most hill -fort s were in continuo us or near conti nuo us use for several centur ies, and during th is time the shape and na tur e of the fort wou ld have changed, as too might the size and politica l status of th e co m mun ity it served. Like an y long-lived defensiv e wor k, im provemen ts would have been undertak en to reflect changes in warfar e and weaponry, such as the introduction of new fort-building techniques or types of missile weap on s into Britain. Similarly the interior of th e fort wou ld also alter ove r tim e, and archa eological excavations on several sites have proved that building types, the organ ization of th e interior and even th e size of th e settle me nt were all sub ject to cha nge .

Maiden Castle To better understand th e way hill-forts developed with the passage of time we could do worse th an to look at probably th e most famo us examp le: Maiden Castle in Dorset (see pages 38-39). This, th e largest hill-fort site in Britain , was subject to two large-scale scientific investigat ion s, allowing us to trace its develop men t and to und erstand the way it fun ction ed as a settle ment with more certainty than man y ot he r sma ller sites. Maiden Castle was first excavated by Sir Mortimer Whee ler between 1934 and 193 7. Further excavations were carried out in 1985-86. It has been proposed th at th e name probably derived from th e pre-Celtic nam e for th e hill-fort, 'Mai Dun ', wh ich approximates to 'big fort '. It occupies a prominent saddle-sha ped ridge two miles from th e town of Dorchester, presenting a striking

I

T he development of the fortifications Wheeler's excav ation was the first large-scale scientific study of a British hi ll-fort , and helped sha pe our understanding of th e peopl e who built these fortificati on s. He proved th at th e fort was built in severa l ph ases, th e first bein g conce ntrated o n the eastern half of th e ridge. An ear lier Neolith ic cam p and raised causeway o r ba rrow had already been built o n th e same site, but by th e tim e th e fort-builders arrived aro und 500 BC th e tra ces of th is earlier settle me n t and bank had all but disappeared. The first fortification co nsisted of a dog-legged bank and ditch du g across th e ridge from rough ly north to south, th ereby creating an enclos ure bo unded on its rem ain in g three sides by th e stee p slope of th e ridge's eastern end. The ban k was revett ed using tim ber, and pierced by a woo den gateway. Anot he r ban k ran aro und th e top of th e ridge, and was pierced by a gatew ay at its eastern en d. The enclosure was certa in ly occupied, as t races of timber enclosures dating fro m this period have been found th ere. Duri ng th e next century th e de fences fell in to disrepair, the rampa rts collapsed and th e ditch silted up. Howeve r, aro und 400 BC t he locals decid ed to rebuild th eir hill -for t, thi s tim e extending it to encom pass th e who le of the ridge, an area of some 18li hectares (46 acres).

two cha n ne ls by a median bank. The rampart s and outlying ditch were exten ded to th e western side of th e ridge, wh ere a second en trance was co nstructed, again with a semi-circular lin e of oute r work s. Both ram parts were pierced by two gateways approx imate ly 50m apart. Th is ph ase of th e development of Maid en Castle ha s been link ed to th e cultura l ph ase kn own in Iron Age archaeology as 'A Culture', namely th e first identifi able British culture of th e Iron Age. Althou gh th ese peopl e took advantage of th e new iron-making technology import ed from th e mainland of Euro pe, it is now th ou ght th at th e majorit y of th ese peopl e were indi gen ou s inhabit ants of th e region. Aroun d th e same tim e as Maiden Castle was expa nded a new group app eared in southe rn Eng land, th eir route traced by th e rem ains of th eir distin ctive pottery, th e use of th e sling and th eir ow n parti cular ideas about fortifi cati on. These peopl e were clearly identifi able as Celts. Arou nd 250 BC th ese members of ' B Cu lture', as th ey are known, began to make th eir mark on Maid en Castle; its defen ces went th rou gh an ex te ns ive revision . As an offens ive wea po n th e sling proved superior in both ran ge and firep ower to th e javelin used by th e 'A Culture' inhabitants. Wh ether thi s defen sive improvem ent was mad e by th e old gro up or th e new is largely unknown, but th e new sche me was certa in ly design ed to coun te r an d to take adva ntage of th e sling's capabilit ies. On th e north ern side of th e ridge a seco nda ry bank and dit ch was created, suppo rted by a sma ller spur bank on th e n orth-western face of th e ridge to scree n th e western gateway. On th e south side of th e ridge two banks and dit ch es were added, in addition to additiona l bank defen ces in front of both gateways, design ed to fun ne l attac kers into a 'killing zo ne' for slings hot. Fina lly the origina l inner ramp art was repaired an d hei ghten ed , the extra scale of the bank su ppo rted by a sto ne revetm ent buri ed on th e in ne r face of th e ea rthe n ba n k. Th e final form of Maid en Castle's form idable array of defen ces was prob abl y co m pleted at so me stage during th e ea rly 1st cen tury Be. The rampart s were en larged once again , wh ile a substa ntial co unte rsca rp bank was ad ded wh ich enc ircled th e who le ridge . Wha t was most sign ificant about thi s th ird phase of improvem ents was th e streng the n ing of th e two gate ways. On th e easte rn en d th e outlying defen ces of th e o ld gateway were filled in or dem olish ed, an d in th eir place a series of two large fortifi ed rampart s were added, both fro n ted by a dit ch an d a sma ller co un te rscarp bank. On th e weste rn end of Maide n

Castle the old defences were greatly strengthened, and augmented by ano ther outlying rampart, ditc h and cou n terscarp ditch. In addition smaller banks with in the gateway co mplex acted as barriers to funnel attackers trying to round th e last outlying rampart before th e gateho use. The twin gateways th em selves were greatly streng the ne d with sto ne revetmen ts, as was th e north-western en trance to th e gateway where it passed the first line of th e outer defen ces. Betwee n th e twin gates and th e first outer rampart a row of guard huts hou sed th e gate garr ison , suggesti ng a level of m ilitary organizatio n th at had been lacking in previous defensive systems . In mo st of th e outer dit ch es leading to th e gate ho use (and possibly elsewhe re aroun d th e fort perim eter) woo de n sta kes were emplaced as chevaux de {rise, obstacles designed to deter or hinder an y attacker. Finally, firin g platforms ma y well ha ve been installed at various points along th e oute r rampart s, leading to the gatehouse, so that a 'for lorn hop e' o f slinge rs could shoot into th e flanks or rear of an assault part y. By now Maid en Castle had develop ed int o what was probably th e best-d efended hill- fort in Britain . Around the time th ese fina l improveme nts were being mad e to th e defences a new gro up arr ived in southe rn England. Known as 'C Cultu re' peopl e, th ese in comers were Celts of th e tribe known as th e Belgae, wh ose origins lay in what is now northern France and southern Belgium . Within half a century these inc omers had exte nded th eir con trol over most of south-east England, an d by AD 25 at th e latest thi s had extended as far as Maiden Castle, wh ich th ey may well have occ upied. Certain ly their influ en ce was felt wit hi n th e fort. The Belgae, or those wh o ado pted th eir ways, repaired th e ramparts by rein forcin g the ba n ks with a layer of earth and streng the ned th e wall walk an d palisade th at surmo u nted it. Strangely eno ugh thi s palisad e was mounted on th e in ner side of the rampart, leaving th e men who patrolled it exposed to fire from outside the fort. This has been explaine d as being mor e of a secur ity barrier th an a defen sive work - controlling access to th e rampart s as a privilege reserved for th e warrior elite of th e garrison. The posts su ppo rting this palisade were sunk deep into th e outer edge of th e ba n k, and so in effect they dou bled as a reinfo rceme nt for th e sto ne revetment bu ried in th e bank itself. These imp rovem ents did not help th e defenders when th ey encountered Vespasian's II Legion in AD 43. Maiden Castle was captured without much difficulty by th e legionary commander, wh o would soo n become a Roman empero r. After capturing the hi ll-fort th e Rom an s destroyed th e fort 's gateways, leaving it defen celess. The site rem ained occupied for ano the r three decades, until th e Romans established a new region al capital two miles away in Durnovaria (Dorchester), named after th e local tribe known as th e Durotrigii. Around AD 70 Maiden Castle was aband on ed, and its once formidable defen ces became a place of pasture. The Rom an s had one fina l humiliation for th is great symbol of Celtic power. In AD 3 13 Ch ristianity becam e th e official religion of the Roman Empire, and around AD 380 a small square temple was built on the eastern side of th e ridge, within th e bounds of th e original fort. A large circular sh rine was th en built beside what was once the main th orough fare of th e hill-fort, occupying a site that may once have belon ged to th e prin cipal Celtic roundho use in th e fort. Both structures had fallen int o disuse by th e end of th e 5th cen tury AD.

but thrivin g community, perched o n the very edge of Roman-occupied Britain.The defences of th e fort were not greatly st re ngthe ned ove r time , but rath er a se ries of small outworks we re added - guardhouses th at cove red the steep approach roads to the top of the summit. The rem ains of wall-ringed field enclos ures surround the fort, prov ing th at Trer Ce iri remained the ce nt re of a th riving agra rian co mmunity thro ughout its period of occupatio n, and t hat its pop ulation increased significantly during the I st centu ry AD, prob ably t hro ugh the arr ival of refugees fleeing the Romans .

T he settlement The one feature th at bo th excava tions at Maide n Castle failed to reveal in any detail was the configura tion of the hill -fort 's inte rior. Afte r all, th e reason the fortifications existed in th e first place was to protect the Iron Age community who lived and wo rked th ere. Archaeology has revealed a littl e abo ut how th ese people lived , and h ow th eir settleme n t was organized. Th e first settleme nt there was a Neo lith ic one, establishe d aro und 4000 Be. However, th e commu n ity th ere was relati vely small - prob ably no more th an 100 peopl e, based on th e size of th e causeway cam p th ey built . It seems to have rem ain ed a focus for the Neo lithic people of South Dorset, as abo ut 3 50 0 BC the long ban k barrow was built, suggesting th e ridge was seen as a centre of religio us importance. The area was aba ndo ned a few centu ries lat er, and it was no t until the very end of th e Neo lith ic period , aro und 22 50 BC, that archaeologists have been able to trace any furth er act ivity. During th e Bron ze Age there seems to have been little occupation, although th e nearb y Frome Valley becam e a relatively well-p opulated area. Th is all cha nge d aro und 50 0 BC, whe n th e Iron Age peo ple of th e region bu ilt th eir hill -fort th ere. Although little trace rem ains of th e settleme nts created by either th e Neolithic sett lers or th eir early Iron Age ancestors, by comparing Maid en Castle with ot he r sites in th e area we can see th at th ere seemed to be a tenden cy for communities to congregate int o easily defended settleme n ts dur ing thi s period , prob ably du e to an increased level of social unrest. The trouble with Maiden Castle is that th e

Consequently grain storage becam e important, and th e ability to store produce in locations such as hillfort s suggests an increasing level of centralized con trol over the population. In othe r wo rds Maiden Castle probabl y acted as a seat of govern me n t for a local tribe, whose influ en ce extended down th e Frome Valley to th e south-east, and southwa rds towards the coast at Portl and. There is evidence that th e land with in th is hint erlan d was extensively farmed duri ng th e Iron Age, and that it was consi dered of good quality. The development of so man y hill-fort s in th e Dorset area during th e early Iron Age suggests that thi s land was contested by neighb ouring commun ities. It was th erefore a tim e of upheaval, when th e inhabitants of Maiden Castle needed th e security offered by a well-defend ed hill-fort settl em ent rath er th an by scatte red farmst eads and unprotected Villages. The earliest traces of stru ctures within the encl osure of Maiden Castle date from aro und 400 BC, wh en th e h ill-fort was expanded to enco mpass th e entire ridge. A series of limit ed excava tions hav e gone some way to sho wing how th e site deve loped , but in ma ny cases, whe re geophysics rather th an excava tion has to be relied up on , it is impossible to say wha t structures date from thi s mid-Iron Age phase of occupatio n and whic h were built later. It does appear th at th e large and slightly ridged plateau th at made up th e enclosure con tained a cen tral metalled road running close to but not along th e spine of th e ridge, with what might ha ve been non-metalled side roads radiating outwards from th e eastern gateway. It seemed th e inhabitants avoided building either roadw ays or structures on th e line of the Neolithic barrow, probably ou t of respect for the dead th ey imagined lay beneath it. Archaeo logists believe that during th e initial stages of th e fort's occupation settleme nt was concentrated near th e median ridge of th e fort, leaving a lot of ope n space towards th e edges of th e ridge. The settlement th en expanded outwards. The only clear evidence of these earlier phases has been th e discovery of a number of rubbish pits and post-holes in th e centre of th e fort. Traces of a 'fourposter' hut was discovered - a rectan gular structure which has also been found in other Late Iron Age sites, particularly in th e hill-fort s around th e Welsh border. It has been suggested th at th ese structures were too small to represent hou ses, so it is surmi sed that th e buildings were storage barns. However, it has also been suggested th at because the se structures were concen trated near th e ramparts of th e fort th ey could be watchtowers of some sort, or even platforms built to hon our th e dead . We are on firmer ground in th e later ph ases of occupation . Geophysical surveys have show n th at an irregular scatte ring of timber and th atch roundho uses occup ied th e bulk of th e site, in terspersed with sto rage pits and refuse dumps. The

excavation co n ducted during th e 1980s also revealed a littl e m ore abo ut the occupation of th e fort, and a number of these rou nd houses were excavated . The rema ins of three huts were d iscovered in 1986, the largest of whic h measur ed almost six metres in diameter. These struc tures were typical of the hu ts associated wit h the Iron Age in Britain: wooden circular structures, surrounded by a sligh t ditch and ba nk . The build ing was centred on an open hearth, while traces of an oven were found to one side of this . The main st ructural timbers of the dw ellin g co ns iste d of a circle of upr ight posts hold in g up a frame of timber bea ms . The en trance to the hut faced so uth , an d was delineat ed by a sma ll fen ce leading o nto a lim estone wa lkway. A post-h ole suggests th at the en trance was o nce secur ed by a substa n tia l woode n door. The excavating team also d iscovered that th e stru cture was in use for a lon g time, and was rebu ilt at least th ree times during its occu pan cy. Cu lt ivatio n a n d qu arrying has des troyed m uc h of the evidence of other huts o n to p o f the plat eau , so all we ca n do is ima gin e th at d uri ng t he Late Iron Age th e h ill-fo rt co n ta ined numerou s st ruc tures of this typ e.

They were replaced with storage barns, which im proved the ca pac ity an d the su ita bility of grain storage within th e hill-fort. Even m o re spectac ula rly, the huts appea r to h ave bee n reorgan ized . Rather than bein g scattered aro un d the rid ge, they we re co ncen t rated into rows, a littl e like modern subur ba n st reets, with eac h roundhou se en clos ure space d eve n ly, a nd far closer to each oth er than before.

Maiden Castle, England,AD 43 Maiden Castle is the largest and best-known hill-fort in Britain, its multivallate defences dominating the Dorset countryside. The site is shown as it would have looked at the time of the Roman invasion of Britain in AD 43, when it was almost certainly attacked by a Roman legion. By that stage its defences consisted of a formidable series of banks and ditches, the last of which - the inner rampart of the fort - ran around the edge of the ridge on which the fort stood.A series of archaeological investigations of the site in the 1930s and the 1980s has revealed a lot about how the fort would have looked in this period, when it provided a safe haven for a com munity of as many as 1,000 people. Gran aries and storage chambers occupy the outer parts of the enclosure. while the main habitation area is concentrated towards the centre of the site.The hill-fort is dominated by the complex defences of its two gateways. the most impressive of which is the formidable eastern gateway in the lower right (an earlier version of which is shown in the upper right inset). The se ries of outer banks and ditches was designed to break up any attack. and to expose the attackers to a hail of javelins and slingshots from both firing platforms on the outer wo rks, and the fighting platform that ringed the inner rampart. It has been suggested that th e ro undhouses in front of th e gat eway served as guard huts.

Thi s reorgani zation of th e houses suggests a major social change at Maid en Castle. First ly, it shows that whoever was in cha rge of th e comm unity was ab le to change th e bas ic structure of everyday life for what he or she probably saw as th e greate r goo d. Archaeologist and the 1986 excavatio n director Niall Sharpl es arg ued that: The co ns truc tio n of regimented rows of ho uses may h ave been an attempt to break down the extended kinship ties of individual fam ilies and stren gthen th e im por ta nce of the larger urba n comm uni ty. The va riatio n of house design , h owever, suggests that th e identity of th e ind ividua ls h ad no t been totally abso rbed by wha tever co llective ideals were in force and is in mark ed co ntrast to th e situa tion in some ot he r hill-fort s.

This reorganization of th e enclos ure in evitably in volved a major upheaval for the co m m un ity, and for th e first time th e prese nce of reside n tial an d com mu na l areas can be traced with in th e int erior of th e hill-fort. Large areas appea r to have been devot ed to grain sto rage, as th e rem ain s of sto rage barn s - th e struc tures wh ich replaced th e earlier grain sto rage pit s - have been discovered. It seems as if th e peopl e who ran th e co m mu ni ty wanted to be able to feed a larger population th an normal in th e event of an attack, or needed additiona l grain to feed a workforce brou ght in fro m th e su rrounding countrys ide to help improve th e defen ces of th e hill -fort. Grain storage also help ed provid e a mean s of cur rency and excha nge in th e rural Iron Age eco no my, and its presen ce would have help ed enco urage th e creat ion of spec ialized trades and industries, whe re lab our was paid in eithe r cash or gra in. Afte r all, th e Belgae used COinage, wh ich suggests tha t by th e tim e th e Rom an s arrive d th e eco no my of Maiden Castle was based both on agrari an produ ction a nd on trade and manufacture, th ereby mir rorin g th e activity found in th e region during th e Bro nze Age. After th e Rom an in vasion of AD 43 an d th e sligh ting of th e gate ho use defen ces by th e Rom an army, this well-organi zed social struc ture appea rs

to have broken down . For the next few decades the population appeared to decline steadily, and buildings were once again scattered across the site rather than grouped together in streets. Only one house from this period was firmly identified in the 1980s, but it is clear that some if not mos t of the lat er 'suburban ' houses fell into disuse. Other evidence of occupation is sparse, although Professo r Wheeler uncovered the remains of five ho uses and several storage pits as well as an iron-working area that he associated with the period im mediately after the Roman invasion . Th ere was also evidence that the sett lemen t spilled out through the disused eastern gateway and that buildings were established within th e banks of the fort's outworks beyond the gate. At the same time many of the out lying ditches were filled, suggesti ng a change of em phasis from defence to accessibility. The settleme n t was abandoned a few decades lat er, as th e regio nal cen tre of power shifte d two mil es east to th e n ew Roma n civitas pe regrina (regional cap ita l) of Durnovaria (Dorc hes ter).

T he economic and political centre Maiden Castle served a n agrarian co mm un ity, and so farming rather th an trade or manufacture was of primar y imp ortan ce to th e peop le wh o lived there. However, it also served as an im portant urb an centre that dominated th e surrounding region , and traces of its political and eco n omic power h ave been discovered. Food prod ucti on incr eased dur ing th e Iro n Age as new farm tools and techniques helped im prove cro p yield, particularl y of wh eat and bar ley. At the same tim e archaeologists h ave shown th at livestock was farm ed within the area of Maid en Castle, and th e rem ain s of catt le, shee p, pigs and chic kens have all been foun d with in th e hill- fort enclosure, along with th e rem ain s of dogs, goats and wild a nima ls (dee r and hare). Th is all suggests th at food was readil y available at Maide n Castle during th e Iron Age, and th at neighbou rin g farme rs would probably dr ive the ir livestock or transport their grai n to th e site whe re it would be exchanged, sold or han ded over as a form of taxa tio n. Maiden Castle was well placed as a manufacturing cen tre, as local supp lies of co pper and tin ore were availab le within its hin ter land . Archaeo logists have recovered substan tial quantities of bronze and iron tools, and altho ugh th ere is no evidence that bronze ob jects were ever prod uced withi n the h ill-fort, Professor Wheeler did de tect signs th at bro nze was being reworked at a workshop located in the south-west corne r of the fort. Iron was certa inly manu factured on th e site, but the on ly clear evide nce for th is is in the perio d after th e Roman invas ion. It is mo re likely th at iron tools and othe r objects were manufactur ed in specialist centres elsewhere, and then bro ught to Maiden Castle as ob jects for barter. There is evidence th at pott ery was pro duced within the con fin es of the fort, as th e remains of clay-baking ovens were discovered. However, Maiden Castle lacked a ready supply of water, and so other bett er-p laced location s were probably used to supply its in habitants, who purcha sed the ceramic goo ds th ey needed in exchange for agricultura l produ ce. The on ly ind ustr y th at may well have thri ved on th e site was textil e prod uction , a business wh ich left littl e in th e way of surviving evidence apart from bone tools used in the treatm ent of wool, as well as bobbins, pin s and needles. Witho ut in dustry or a religiou s cen tre it ca n be argue d that Maiden Castle was not mu ch of a sett leme n t . It import ed most of its man ufactured goo ds from elsewhere, an d wha t it did produce was pro bably just eno ugh to supply its ow n po pu lation. Archaeologists have described settleme n ts such as th ese as proto-ur ban - populati on centres that rely almos t exclusively on an agrarian econom y for th eir surv ival. This mean s Maide n Castle m ight have been a substan tial settleme n t wielding co nsiderable in flue nce ove r its hinterland, but it was not a town in the accepted sense. It is bette r viewed as a fortified ru ral co m m un ity, which exp lains why it was so easily ove rsha dowed by th e establishment of a permanen t Roma n town ship offering all th e trad in g o pportu nit ies th at Maide n Castle lacked .

Celtic fortifications In operation Hill-forts today are deceptive places: the smooth, grass-covered banks and ditches have been rounded and weat he red over the centuries, and th e approach to th em, alt ho ugh often somethi ng of a climb, is no longer an expe rience fraugh t with dan ger. It wo uld have been a di fferent sto ry at the height of th e Late Iron Age, where th e ramparts wo uld h ave been stee per an d high er, the dit ch es impassa ble, and th e rampart s lined with well-armed defen ders. Sta kes and im pedime n ta wou ld h in der any approac h over th e oute r banks and dit ch es of the fort, wh ile th e mai n gate itself would present a labyrinth ine trap to an un wary ene my.

The principles of defence The most basic form of defens ive work was a sim ple timber palisade, ofte n associa ted with a bank and outly ing dit ch . Archaeological evide nce shows th at th ese were usually built by sin king a series of upri ght posts into th e top of th e bank, th en linking th ese togeth er to form a rail-type fen ce. Thi s th en suppor ted th e up right sta kes th at forme d th e frontage of th e palisade. In almos t all known exam ples th e timbers were slotted, pegged or tied togeth er; th e use of iron nails was extreme ly rare. Naturally eno ugh th e on ly surviving evide nce of th ese structures is th e post-h oles, altho ugh in a few cases traces of th e palisade itself have been detected . Man y Iron Age or Lat e Bron ze Age fort ification s app ear to h ave begun as a palisaded enclos ure, and were on ly develop ed into more com plex defended sites later. For exam ple, at Dinorben in Co nwy a line of 5th-cen tury BC post-h oles was found ben eath th e rampart , suggesting a palisade predat ed th e existing bank. Some of th ese palisades have been dat ed as early as th e 8th cen tury BC, some three centuries before th e appea rance of th e co nven tional rampart and dit ch hill-fort s. A development of th e basic palisade was th e box rampart , whe re a double lin e of posts was su n k into a bank, some two or three metr es apart, th en 'laced' together to form a wood en fram e. The struc ture was th en filled with soil to creat e a solid rampart. Th e defen ces of Hod Hill, Dorset were built usin g this method . At Dan ebury, Hampshire, arch aeo logists di scove red that th e fort was

An exam ple o f this typ e o f co ns t ruc t io n is found at Cissbu ry, Sussex, a large 20-hectare site whe re the palisad e for m ed th e o ute r retain ing wa ll o f an eart h en ba n k behind it . Thes e earth en ba nk s ten d ed to be hi gh er than earlier st ruc t ures, with a steeper ou ter face to ma ke it h ard er for an att ack er to rea ch t h e pa lisad e or breastwork at the to p of th e ra mpart . Similarly a st eep in ne r face to the ram part wa s ea sier to co n st ru ct, as it reduced t he amou n t of so il th at h ad to be moved. At Wand lebury, Cam b ridgesh ire, th e ear lie r box st ruc tu re was co n vert ed into an oute r de fensive lin e, wh ile a larger t im ber-fronte d bank was bu ilt t hat rese m bled the o n e fou n d at Cissbur y. What these rem ains fail t o p rovide is any so lid ev ide nc e fo r the palisad e or br eastwor k th at ran alo ng the to p o f th e ra m part. Presu mably the timber revetment doubled as a pa lisade, as it was h igh er th an th e bank for me d behind it. Alth ough sto n e-built rampart s we re ver y different in appearance to eart he n ones, a sim ilar approach was ado pted. The hi ll-for t at Tre'r Ceiri in Caern arfo n was sur rou n ded by a sto ne -bu ilt ram pa rt whe re th e oute r face also form ed th e palisade. A stone wa lkway ran behind this out er face, and the wa ll the n descend ed toward s t he interior of th e enclosure by m eans of two ste pped revetments or te rraces, wh ich im pa rte d greater streng th to th e who le struc ture . A m ore co m plex stone ram pa rt is fou nd at Worlebury in Some rset, wh ere archaeologists h ave shown th at th e origina l com plex o f wa lls once stood to a height of ove r 10m. As at Tre'r Ceiri th e main ram part was supported by a series of sto ne revetmen ts o r terraces stepping down toward s th e interior of th e fort, wh ile th e outer face presen te d a n ear ve rtica l face to any att acker. In effect thi s stre ng the ne d th e defen ce, because eve n if th e outer wa ll were da maged, th e stone revetments beh ind wo uld serve as seco ndary walls, thus m aintaining th e in teg rity o f th e defen ce. A var iatio n of th e co nve n tiona l sto ne ram part is found in th e 'vitrified ' forts of Scotlan d, whe re the walls were delib erat ely sub jecte d to th e effects of fire. The process of setti ng fire to th e st ruc ture fused th e rocks together in va rious degrees, an d in some cases prod uced a di stincti ve glass-like coa ting th at served as a binding age n t. Exam ples include th e Tap O'Noth on Bennachi e, Gra m pian; Barr y Hill, Perthsh ire; and Craig Phadrig outside Inverness. Sim ilar vitrified struc tures were found in Ireland an d in Cen t ral Europe, but outside Scotlan d th ey are no t fou n d elsewhe re on th e British m ainland. In man y cases th e Vitrified wa lls were th en reinfo rced or revett ed by un vitrified sto ne, ofte n built up on both the outer an d inner faces of th e vitri fied rampart. However strong th e ram pa rts of an Iron Age fort were, th e wea kest point of th e site was always th e gateway - an d it was presumab ly th ere th at an attacker wo u ld conce n tra te h is effor ts.

attackers with javelin s and slingsho t sto nes. The simplest form of gateway would be an open entrance, sealed with a temporary barrier such as cut logs or felled trees. Usually th e passage th rough th e rampart was faced with stone, the n blocked by one or more wooden gates. Maiden Castle appears to have had two gateways, separated by a sho rt length of rampart. In some fort s, such as Dino rben, a gateho use or guard post lay beh ind th e gate itself, wh ich suggests th e presenc e of a perm an ent gate garrison. At Maiden Castle one of two small guard posts located at th e eastern en trance was equip ped with a hearth, whi ch supports the the ory th at th ese posts were perm an ently manned. One surprising aspect is th e lack of iron fittings associated with Iron Age gateways. At Sou th Cadbur y, Som erset, and Hembury, Devon , iron rings were found whi ch might well have form ed part of a gate h inge. It appears th at in most cases these h inges, like th e gates and gateposts themselves, were constructed using wood. The width of th e gateway seems to have varied considerab ly; at Danebury in Hamps hire th e gate itself had two leaves or sides, and was sup ported in th e centre by a post set int o a stone-lined post-hole. At Breden Hill, Gloucestershire th e gateway span ned a Sm-wide road, and was constructed in a similar fashion to Danebury. What is int erestin g about both th ese gateways is th at both were set between lon g passageways, formed by th e ramp art s turning outward (at Danebury) or inward (at Bredon Hill). Defend ers on the ramp arts could th erefore sho wer th e approac h to th e gate with sto nes even more effectively th an th ey could when defending a more conve ntiona l gateway system. At Breden Hill it app ears that th e line of rampa rts was spanned by a foot bridge whic h crossed the approach road, wh ile th e gatewa y itself was set some 20m further back, at the end of the inwa rd-turning horns of th e bank. Some archae olog ists have suggested th at these gateways or footbridges were decorate d with troph ies of war such as severed hea ds or skulls, or augmented by some form of triumphal arch. However, the evidence for these features is either circums tan tial or no n-existen t. The gateway itself was usually approached th rough a series of outer works, which were designed to make th e attackers turn and expose their side to the defenders. If the attacker was equipped with a shield then a left-hand turn in the

approach meant th ey would lose th e protection of th e shield as th ey adva nce d. At Hod Hill th e approach involved a turn to th e right, whi ch suggests th at an un fin ished outwo rk in front of th e main gate was prob ably intended to provide a forwar ds fighting position for th e defen ders, whe re th ey could assault th e att ackers in th e rear and right flan k as they advanced towards th e gate. At St Catherine's Hill in Hampshir e th e approach to th e gateway was free from any such obstructions, but post-h oles on eithe r side of th e en trance suggest a walkway migh t have pro jected forward to flan k th e gate itself in a fashio n similar to the hornworks found at Dan ebury. An addition al obstacle was some times used in th e form of chevaux de (rise; these were wooden stakes em bedded in ditch es or banks to slow th e advance of any attacker, wh o would have to thread th rough th e stakes. In Wales and Scotland jagged rocks were used as an alternative to wooden stakes, whil e in a few sites in Wales such as Pen-y-Gaer in Conwy boulders were strewn outside the perimeter to achi eve the same effect. In short the people of Iron Age Britain used every means they could to place an attacker at a disadvantage: building their forts on h illtop s, creati ng networks of banks and ditches, constructing complex en trances, and placing additio na l obstacles in the path of any attac k. As such they used all the princip les of defen ce th at could be foun d in lat er period s. Their on ly lim itation lay in th e manner in whi ch th ese Celtic peopl es fough t, and in the limi ted weaponry ava ilable to th em . As long as th ey faced oppone nts from a similar cu lture, their fortifi cat ions were virtua lly impregnable. However, whe n they encoun tered a tech nologically superior opponent the weaknesse s of th ese defensive syste ms were exposed, and the y proved as defe nsib le as a medi eva l castle attacked by Renaissanc e artillery, or stone-buil t Victo rian fort s bombarded by mo de rn rifled ord nance.

T he defence of a hill-fort The Celtic fortification s of Britain were certain ly not designed to withstand an A section of th e Bro ch of Mousa att ack by a professional standing army suc h as th e one fielded by Rom e in th e shows how the walls were dou bleIst cen tury AD. The Greek historian Strab o said of th e Celts that th ey 'were war skinned above groun d level. allowing mad, high spi rited, and quick to battl e, but othe rwise straightforward, and not space for t he stairwa y between of evil character'. By nec essity th e way th ey designed th eir fortifi cati ons was th e tw o walls.As at Gurne ss. in fluen ced by the manner in which th ey waged war. In particular, th eir ability the groun d floo r co ntained wells and storage pits. (Stratford Arch ive) to defe nd brochs, hill-f orts or oth er fortifi ed sites depended on th eir tactical ability, their available weapons, and th eir skill in using th em . It is important to cons ider th e weapons at th eir disposal in order to und erstand wha t part th ese played in the defence of a fortified position. We know from th e writings of Rom an historians such as Caesar, Tacitus, Dio and Sueto n ius amo ng others how the Celts fought , and what weapons th ey used. The principa l missile weapon in use in Britain was the sling, which fired a sma ll rou nd sto ne a distance of up to 60m . Altho ugh primaril y a hun ting weapon, it could also be used in time of war. The large caches of slingshot stones recovered from several hill-forts are clear in dication s that thes e weap ons were considered crucial in th e defen ce of a fortified position. An opponent would rarely be killed by a slingshot, but th e sto ne it fired could break bon es or crack skulls. A hara ssing fire could be aimed at an approach ing force, and as th e attackers clamb ered over th e outer lines of banks and ditches they would c-o SfCOON be slowed, thus rem aining in optimum range for zo I longer than if their approach went unhampered.

LEFT Hill-fort gates: Dinorben, c.500-1 00 Be The hill-fort of Dinorben,Wales made the best poss ible use of th e natural defences of the site on wh ich it was built, pro tected on th ree sides by a steep escarpment, as shown in the plan view at top right.The remaining side was protected by a th ick stone rampa rt and three outly ing ditches.The site was excavated on three occas ions, and this information allows us to reco nst ruct the three phases of deve lopment of the fort's gateway. In the first phase ( I) a simple stone-fronted wall was built aro und a timber-laced frame , although there is evidence that this st ructu re replaced an earlier wooden palisade. bank and

ditch. A bulwark on one side of th e gate provided a conven ient platfo rm for the defe nde rs. During the next phase (2) the o riginal walls we re extensively widened to around 10m. protected by a stone-filled ea rthen glacis. The gatew ay itself was flanked by two guard chamber s, while a deep ditch encircled the landward side of the fort. In the final phase (3) the stone ramparts of the fort we re heightened to create a bre astwork, while additional ditches we re cut in fro nt of th e gateway.The approach to the gateway was revetted using stone, and angled so that any attacke r wou ld have to expose his unshielded side to the defende rs' fire as he approached.

Once th e ene my reach ed th e last ditch th ey would be with in javeli n ran ge. Although th ey were slow in flight, if eno ugh light th rowin g spea rs were th rown at a target th e barra ge wo uld almos t certa in ly cause casua lties, bein g di fficult to avoid . Given that th ey were usually th rown ove rarm from a rampart aga inst troo ps approaching th e firer from below, th ey were difficult weap on s to aim with an y effect. Instead th ey should be co ns ide red mor e of an indirect fire weapo n - a last form of defen sive fire befor e th e attackers reach ed th e rampart or gateway . Finally, th e defenders would throw wha teve r th ey had to hand, such as piles of roc ks. Once th e attac kers h ad scaled th e bank and had reac he d t he rampart, th e fighting wou ld be hand-to-h and, usin g spear, swo rd an d sh ield . Bows were almos t certai n ly used as hunting wea po ns by th e Celts in Britain , altho ugh th ey appea r to h ave been fairly rare. Strange ly th ere is no accoun t of th em bei ng used as a military wea po n . The practical limitat ion s of these weapons influenced th e way th e Celts bu ilt fortifications. After all, th e peo ple who built the brochs and hill-forts of Celtic Britain almost certa inly had no experience of the Roma n way of war, and had no in kling of the vast techn ological gap between their defens ive methods and the Rom an form of siege warfare, with its secure fortified camps, siege engines and concen trated bombardments. They built to defend them selves against wha t they knew - raids by fellow Celts, or even large-scale assaults a determined tribal enemy. Th is meant maintaining a welldefended perim eter, and encircling thi s with man-m ade or natural terrain designed to hinder an attacker, eithe r by forcing the m to endure a rain of missiles as th ey approach ed th e inner ramparts, or by tirin g them as they struggled to climb up towards th e waiting defenders. Given th ese parameters, hill-forts app ear to have been successful in doing what th ey were designed for. Although we know less about how brochs were defend ed, th eir similarity to later Norman keeps or even Border Reiver stro ngho lds spea ks volumes about th e practicality of their design . We know a littl e abo ut th e type of wa rfare for wh ich th e great hill -forts were built fro m Julius Caesar, wh o describ ed Celtic siege tact ics as th ey existe d in th e mid-l st cen tury Be. His com men ts are brief but revealing: There was a town of th e Rem i, by nam e Bibrax, eight miles dista nt from th is camp. This th e Belgae on th eir march began to attack with great vigour. [The assault] was with difficult y sustained for th at da y. The Gauls' mode of besieging is th e same as th at of the Belgae: when after having drawn a large numb er of men around th e whole of th e fortifications, sto nes

When nig ht had put an end to th e assault, lccius, who was then in comma nd of the tow n, one of the Rem i, a man of the highest ran k and influen ce amo ng h is people, and one of th ose who had come to Caesar as ambassado r Ito sue] for peace, sends messenge rs to hi m, Ito report] 'That, unl ess assista nce were sent to h im he could not hold out any lon ger.' (Til e Gallic Wars) Caesar duly march ed to th e aid of th e Remi and dest royed th e Belgae in battle. The acco un t m ight well have been written a cen tu ry befor e th e hill -fort s of Britain faced an attack by th e Rom an s, but th e tribal warfare for wh ich th e forts were design ed would h ardl y ha ve cha nge d much . Th e mention that th e attackers assaulted the gat e is particu larly revea ling, as the evide nce from Dan ebury and seve ral othe r fort s suggests that th e gate way was th e weak point of th e defen ces. Once th e defenders cou ld reach it they wou ld be able to set it on fire, which mig ht well ha ve been wh at happen ed at Dan ebury. Of co urse Caesar's co m me nt that th e Celts form ed a testudo (or 'to rto ise', an attacking formati on used by th e Roman army) is misleading. It was sim ply the best means he had of describing a den se assa ult co lum n of Celtic warri ors. A problem with descriptions of the Celtic forts of Britain and th e way th ey were att acked or defended is th at we mu st rely on a mi xture of n on- Celti c observers, and ofte n fragm entary or misleading archaeo logical evide nce. Th e combination of the two can some times h ave dr amatically misleading result s. Dur in g h is excavatio ns of Maid en Castle Sir Mortimer Wh eeler becam e co nvin ced that th e h ill-fort had been attacked by th e Rom ans , wh o stormed th eir way into th e fort 's easte rn gateway.

In AD 43 the Rom an II (Augusta) Legion advan ced rapid ly th rough southern Eng land, led by its com ma nde r, the futur e Roman empero r Vespasian. According to h is biograp her, Vespasian subdued 'two very formidab le tribes and over 20 towns' (or rath er hill-fort s), one of which was probab ly Maiden Castle; th e tribes were probably th e Belgae and th e Durotri gii. By th e time th e Romans reach ed Maiden Castle the defenders had prepared them selves as best they could;

Dun Carlo way (Du n Ch arlabh aigh) is another small but well-prese rved Late Iron Age broch , whose re mains perch specta cularly above Lo ch Roag on Lewis.The broch was damaged du ring a 16th-centu ry Highland feud when it was used as a hideo ut. but th e doubl e-skinned natu re of its wa ll construction is all t he mo re clea rly show n by th e ruino us conditio n.

archaeologists have found th e rem ains of substantial cache s of stone shot for slings, th e ma jo rity of whic h appear to have bee n gat hered fro m nearby Chesil Beach. Sir Mortimer Wheeler argu ed that Vespasian would have crossed th e River Fro me wh ere Dorchester now stands, and ha ving seen how formidable th e western defen ces wer e, o rdered his legion to concentrate in front of the east ern gate. The hill -for t, d escribed by th e h isto rian Leonard Cott rell in 1958 as the wo rk of a 'Vauban of th e Iro n Age', wou ld indeed have looked form idable. In h is rep ort o n the excavations published in 1943, Wheeler described what he though t occurred next: First th e regime n t o f a rtillery wh ich usuall y acco m pa n ied a legion was ordered into action a nd put down a barrage of ballista arrows. The arrows have bee n found about th e site, and buried amo ngst the outworks, as was a man wit h an arrowhead sti ll embedded in one of h is ver teb rae (to be see n in th e Dorch est er Mu seum). Follo win g th e barr age, th e Roman infantry adva nce d up th e slo pe, cutting its way fro m rampart to rampart until it reached t he innermost bay, where some circu lar hu ts had recently been built . These were set alig h t, and u n der th e rising clo uds of smoke th e ga tes were sto rme d an d th e positi on carr ied . But resistan ce had been obsti na te an d th e fur y o f th e legionaries was aroused . For a spa ce, co n fus ion, and massacre do mi na ted th e sce ne . Men an d wo men, yo ung and o ld, we re savagely cut dow n be fore th e t roo ps were ca lled to heel. A systematic slight ing of t he defen ces follo wed, whereafter th e legion was wit hdrawn, doubtless taking hostages with it, and th e dazed inhabitants were left to bury their dead amo ngs t th e ashes of th e huts bes ide th e gates . The tas k was carried ou t anxiously and wit ho ut order, but, even so, from few graves were o m itted th ose tr ibutes of food and d rink which were the proper requisites of th e dead . Wit h th eir cu ps an d food -vessels and trinkets, the bones, ofte n two or more skeleto ns huddled into a sing le grave and many of the skulls deeply score d with swor d cuts , ma de a sad and drama tic showing - the ea rliest British war-cemetery known to us. Wh ile today o ne mi ght applaud th e flair wit h wh ich a rchaeo log ists wro te repo rts in th ose days, su bseq ue n t excavatio ns have revealed th at seve ral assu m ptio ns Sir Mo rti mer Wheeler made to develop his ' Battl e of t he East Gate' t heo ry ca n no t now be sustained. His assa u lt theory rests o n th e prese nce of h is 'war-cem etery', but h e failed to show that of the 52 bodies di sco vered there, o n ly 14 had died by vio lent means . Today a rchaeo log ists co ns ide r it more likely th at the site was indeed a cemetery, but o ne wh ich developed ove r ti me , and to wh ich bodies we re broug h t for burial. They were therefore no t bur ied where th ey had fallen in defen ce of th e easte rn ga teway. Mod ern fore nsic st udies ha ve even sho wn that so me o f th ose that sustaine d wounds did n ot die from t hem , but ins tea d lived o n for so me time afte r receiving th em . Wheeler based his acco unt of th e burning of th e fort's guard h uts on his d iscovery of a charcoal layer just o utsi de the eastern gateway. However, archaeo logists now believe th is was produ ced by iron- working, th e evide nce of which in th e form of Celtic arrow hea ds now suppo rts thi s th eor y rather than provides us with evide nce of an assault. After all, bows were used in insign ifican t numbers by th e Celts at this time, and thei r prese nce does not necessarily suggest th at a unit of Celtic archers made a last sta nd on th e spo t. The o n ly piece of evide nce that ha s successfully stood th e test of time is the slighting of the gateway - as revealed by th e collapsed sides o f th e sto ne-clad gateway. The remains were over laid by early Rom an pottery, suggesting the collapse occu rred prior to Rom an settleme n t in th e area - a date co nsistent with the Rom an in vasio n . Th is is co nsisten t with th e idea of Vespasian's progress th rou gh southe rn England, and may repr esent a deliberate policy of destroyin g th e gateways of Celtic fortificatio ns as a mean s of guara nteeing the subj uga tion of the in ha bita n ts.

Maiden Castle was not the only hill-fort attacked by the Romans, or even by the Celts. Around 100 BC the hill-fort of Danebury was destroyed, or at least its gateway was burned down . Tools and horse trappings were abandoned, suggesting a hurried departure of the inhabitants, or a violent end. The remains of 21 mutilated bodi es were fou nd in two grave pits close to the gate , of both sexes, and ranging in age from four to 45. The pits were never properly cove red, suggesting o pen graves int o wh ich th e bodies were th rown . All this poin ts towards a violent end to th e occupation of Danebur y, but once again archaeology sto ps sho rt of explain ing wha t exactly happen ed. Professor Barry Cun liffe, th e di rector of th e Dane bury excavat ion, suggested th at th e end of th e fort was a result of ten sion created by a popu lat ion expansion in southern Englan d, but th e full sto ry may never be known . At Hod Hill, Dorset th ere is evide nce of th e hurried repair an d improveme n t of th e defens ive works, possibly undertaken as a response to news of th e Rom an invasion. The last-m inute im provemen ts did littl e to help th e defe nde rs, as the re is evide nce th at Hod Hill was attacked by th e Rom an ar my in AD 43, almos t certain ly the work of Vespasian and h is II (Augusta) Legion as it marched west through modern-day Dorset. The site was excavated d uring th e 1950s by Sir Ian Richmond, who was parti cularly keen to find evidence of a Rom an assault. Wha t he d id discover was even more intriguin g. One of th e roundhouses withi n th e enclosure was larger tha n th ose aro und it, which might suggest it was th e hom e of a chiefta in or an imp ortant admin istrative buildin g. Archaeologists un covered 11 Rom an ballista bolt s amid its ruins, bur ied nose-first as if fired from th e same locat ion somewhe re outside th e south-east corne r of th e fort. The accuracy of the fire was parti cularly impressive, as th e bo lts were co nce ntrated aro und th at one target. It has been suggested th at whe n th e defe nde rs of Hod Hill refused to sur rende r, the Rom ans dem on str ated the efficiency of th eir siege train by destroying th is one hut - thus prompting th e ga rrison to open their gates. As th ere is no othe r evide nce of battle thi s remai ns a plausible explana tion of what happen ed, but as usual th e eviden ce is open to int erpretation . Certa in ly Vespasian considere d the site to be impo rta nt: he orde red the build ing of a Rom an aux iliary cam p in the nort h-east co rner of the Iron Age defen ces. Ano the r site worth noting is th at of Burnswark in Dumfr ies, a hill-fort flanked by th e remai ns of two Rom an siege camps. Wh en the site was first excavated in 1898 it was assumed th at Burnswark had been besieged by the Rom an s, whose camps were built with in siege-engine range of th e ramparts. However, more recen t excavations conducted in th e 1970s have proved that th e Rom an siegewor ks were

built after th e fort fell int o disuse, almost certai nly providin g a training groun d for the Roma n troops statio ned in southern Scotland during th e late 1st century and early 2nd century AD. In effect th e hill-fort had becom e a Rom an firing rang e. Th is suggests th at th e Rom an s took th e reduction of hill-forts seriously, possibly as a means of preparing for campaig ns against the un-pacified Celtic tribes to the north . These works are in stark con trast to the lack of Roman siegeworks in the rest of Britain, whic h suggests th at if th e Rom an s ever enco untered a fortress that defied th em , th ey would lay siege to it in accordance with th eir milita ry doctrine, establishing secure camps from wh ich to bombard th e defences. Once the defenders were driven from th e ramparts th e Rom an s would probably send in auxiliar y troops to secure the fort, holding their veteran legiona ries back as a reserve. This is how th e Rom an s fough t at Mon s Graupius (AD 84) agai ns t th e Caledon ii, or wh en th ey pacified Gaul, judaea and Dacia. The lack of fort ified camps in th e British Isles suggests th at instances of resistan ce agai nst th e Romans were rare. It is more likely tha t the methods suggested at Hod Hill - a demonstration of Roman mil itar y might - were sufficie n t to force the sur render of mos t of Brita in 's Celtic fortresses. Wh ile it is appealing to imagi ne th e defen ce of sites suc h as Maide n Castle as roma ntic last stan ds by th e Celtic in habitan ts in Britain , th e truth was probabl y mu ch more mundan e. Faced with the futili ty of resistan ce, th e defenders made peace with th e in vad ers, so bringing the era of their political and military independence to a close .

Aftermath The Rom an invasion of Britain in AD 43 sou nded th e dea th kne ll for Celtic culture in southern Britain . We have already seen how h ill-forts like Maide n Castle continued to be used for two or even th ree deca des afte rwa rds, befo re th ey were repl aced by a Rom an provin cial town a few mil es away. In the case of Maid en Castle th ere is ev ide nce that th e pop ulat ion began to drift awa y from th e old fortified settlem ent durin g this period, so that in the space of one o r two gene rations th e population dwindled awa y until on ly a few inhabitants rem ain ed . The Rom an s brou ght peace in th eir wake (if we ign ore th e lceni revo lt of AD 6 1- 63), and th erefor e th e British populati on had less need to pro tec t th em selves and th eir co m m u n ities. Th e Rom an policy of sligh ting th e defen ces of th e hill -forts th at submitte d to th em or were cap tured mad e these places ind efen sible, and speeded th e drift towards n ew settleme n ts. However, th e proc ess of pacification was not com pletely smooth . Archaeologists have sho wn th at th e gateway of th e hill -fort of South Cadbury in Som erset was dest royed aro un d AD 70- 80, wh ich sugges ts th e fort rema in ed occupied after AD 43, but th at it was prob ably attac ked and destroyed by th e Romans in what might well have been a punitive and ret aliator y action . It appears th at th e fort was th en co m plete ly abandoned until th e Rom an occupation of southe rn Britain ca me to an end around AD 410 . The pattern appears fairly clear. In areas where th e Rom an s bro ugh t th e popul ati on directly under th eir co ntrol the o ld fortifications fell into disuse - if not im me diate ly, th en with in less than three generations . In th e north an d west of wh at is n ow Eng land, wh ere th e Roman izat ion of th e populati on was less th orou gh , th e occ upa tion of some forts co n tin ued for man y decad es, and in so me cases th rou gh out th e Rom an period . Un fortu nate ly we know all too littl e about thi s period of occ upancy, including wh ether these sites retained th eir olde r levels of pop ulatio n and sen se of com m un ity, o r if their po pulation declined almost as d ramatica lly as th at of th e hill -fort dwe llers of southe rn Eng lan d. Some hill-forts were certain ly eithe r abandoned or else changed th eir role fro m fortified sett leme n ts into fortifi ed farmstea ds, with a co nsequent drop in populati on. The process of Rom an ex pansio n was a gradual one, as Agricola on ly pu sh ed into wha t is now southe rn Scotl and in AD 82-83. By th en the stro ngho lds of th e Brigant es of toda y's northern England had fallen un der Roman co ntrol, so the Celts of Scotland and Wales rem ained th e o n ly trul y in dependent in d igen ou s tribes in th e British Isles.

Rom an attac k on a hill-fort: Burnswark The evidence for a Ro man assault on a hill-fo rt is scant, although archa eological finds at both Maiden Castle and Hod Hill in southern England both suggest that the defenders att empted to resist the Romans. Burnsw ar k in so uthern Scotland is unique in that the Romans built two milita ry encampments o n eithe r side of the small hill-fort, co mplete with artillery pos itions for Roman siege engines.

Whil e thi s was probably a matt er of prim e locat ion and eco no my of effort, it certain ly appea rs th at th e Rom an s were aware of th e th reat posed by the occupancy of h ill-forts by hostile tribesmen or rebels, and train ed th em selves to deal with just such a situation. Fina lly we have already seen how some hill -fort s such as Dane bury in Ham pshire served as religiou s as well as politi cal cen tres. It is th erefore not co m pletely sur prising th at after its fall Daneb ury rem ained in use during the Roman period , as evidenc ed by cartwheel tracks and Romanized fin ds discovered on top of th e olde r layers of occupancy and defenc e. It ha s been suggested that the fort housed a sma ll religiou s com mun ity, wh ich remained in residenc e to maintain th e sanctity of a sacred site. A sim ilar site may well have existed in Maiden Castle, as th e older Rom an o-British Ch ristian tem ple built th ere might well have been placed on th e site of an older place of wo rsh ip. These Iron Age hill -forts came in to th eir own agai n after th e Rom an s left Britain. Duri ng th e 5th and 6th cen tur ies AD several were re-occu pied, as the defenceless towns of Sub-Roman Britain were vu lne rable to attack by a grow ing number of in vaders. However , it appears th at the peop le of Sub-Roman Britain appeared well aware of the defen sive possibilit ies of sites such as South Cadbur y and Castle Dare, bot h of whic h were re-fortified duri ng wha t is some times known as th e 'Arth urian' period.
