T h e purpose of t h e digwas to find t h e c r e m a t e dremains of a R o m a n cavalryofficer called Longinus. T h eexcavation was a c o n t i n u a t i o nof t h e o n e w h e n James Fawn oft h e Colchester A r c h a e o l o g i c a lG r o u p had famously f o u n d themissing face f r o m Longinus'tombstone.Offering to a god?C o m p l e t e R o m a n pots characterise cemetery sites - they arerelatively rare inside t h e t o w nwalls, where burial was not generally allowed in R o m a n times.Pottery f r o m t h e t o w n centre isalmost always broken discardedrubbish. However, an almost c o m plete white-slipped pot was f o u n din 2 0 0 1 , on a building site atSt Peter's Vicarage on North Hill.Because it was probably deposited c o m p l e t e , it is likely to be partof a votive deposit c o n t a i n i n gf o o d or drink offered to a g o d .Examples of such 'votive' offeringshave been found occasionally inthe past in Colchester; they includea pot on the Lion Walk site whichwas buried with the remains ofthree puppies.T h e work was f u n d e d by t h e Colchester Borough Council.In t h e event, Longinus' m o r t a lremains were nowhere to bef o u n d , a n d the wall had t o b ereplaced. Tendring Construction Ltd verykindly c a m e to t h e rescue a n d sent masterbricklayer Phil ' S w a m p y ' Baker a l o n g torebuild the wall (see picture).Phil was keen to do t h e work because thewall had been built in t h e rare ' r a t - t r a p 'b o n d , a n d he felt t h a t there was littlec h a n c e of his being able to work on a wall ofthis kind a g a i n . He explained t h a t rat-trapbond was developed in the 1800s for t w oreasons. It was designed to stop rats gettinginto roof spaces, a n d , being semi-hollowwith cross bricks, rat-trap b o n d saved onbricks.Later in t h e s a m e year, after t h e g a r d e n a n dwall had been restored, we were verysaddened to learn of the d e a t h of MrCurrey.

A cautionary taleBirch airfield was constructed by the United States Air Force in 1 9 4 3 . In M a y2 0 0 1 , w h e n exploratory trenches were d u g a t t h e edge o f t h e airfield, o n e o fthe more unusual finds was a large pit c o n t a i n i n g e q u i p m e n t d u m p e d by theUS 9 t h Air Force before returning h o m e at t h e end of World W a r 2. No GlennMiller g r a m o p h o n e records or jeeps c a m e to light, but instead a stove,electrical items a n d broken plates were d u g o u t of t h e upper levels of t h e pit.T h e plates are British a n d include o n e s t a m p e d ' R A F 1 9 4 1 ' (see picture),w h i c h seems o d d because Birch airfield was never used by t h e Royal AirForce. There is an archaeological lesson to be learnt here: w i t h o u t thew a r t i m e d o c u m e n t a r y record, it w o u l d be easy to assume wrongly f r o m t h epottery evidence a l o n e t h a t Birch airfield had been a RAF base. We c a n onlyhope t h a t the R o m a n military did not exchange e q u i p m e n t in this m a n n e r .T h e work was f u n d e d by H a n s o n Aggregates.Careful where you stand!Footprints sometimes occur on Roman bricks. T h e culprits a r e usuallya n i m a l s t h a t have been allowed tow a n d e r a m o n g t h e unfired bricks(laid o u t d u r i n g t h e m a n u f a c t u r i n gprocess). But a f r a g m e n t recentlyf o u n d on a site in West Lodge Road,Lexden bears t h e i m p r i n t of a h o b nailed boot a n d pointsthe finger, so to speak,a t t h e brick-makerhimself.The workwasf u n d e d byCrowdel IAssociates.T h e Trust's book onthe archaeology ofColchester up tocirca 1 2 0 0 AD hasbeen reprinted. Thereprint was madepossible with thegenerous support ofthe Hervey BenhamCharitable Trust.City of Victory isavailable inbookshops for 12.50.Trenching by the kilometreThe route of t h e new Northern A p p r o a c h e s Road where it passes t h r o u g h Severalls a n dCuckoo Farm had to be checked for a r c h a e o l o g i c a l remains, a n d so t o o did s o m ed e v e l o p m e n t land a l o n g part of the new road in an area to t h e west of the General Hospital.Accordingly the Trust excavated over three kilometres of trenches by m a c h i n e within t h espace of a b o u t t w o m o n t h s . This is t h e t e c h n i q u e normally employed on d e v e l o p m e n t sitesto ensure t h a t significant archaeological remains are not d a m a g e d or destroyed w i t h o u ta d e q u a t e record. In the event, various ditches a n d gullies of Iron A g e a n d R o m a n d a t e weref o u n d on the site west of t h e hospital, whereas t h e route of the road t h r o u g h Severalls a n dCuckoo Farm was p r o n o u n c e d clear. M o r e a r c h a e o l o g i c a l investigations seem likely in bothplaces.The works were commissioned by Cofton Land and Property (the land west of the General Hospital)and by AERC on behalf of the Secretary of State for Health (Cuckoo Farm and Severalls).Pictures - right: a trench with the hospital in t h e b a c k g r o u n d ; below: view of part of t h e site,looking towards Colchester t o w n centre.3

A British f a r munder the Romans2 0 0 1 saw t h e f i n a l season o f e x c a v a t i o n a t t h e A b b o t s t o n ec r o p m a r k site, w h i c h is q u i t e close to C o l c h e s t e r Z o o .W h a t w a s t h e n a t u r e o f t h e site?W a s it a R o m a n f a r m , a n d how is it c o n n e c t e d w i t hCamulodunum?Where was Camulodunum?' N o m a n is an island', a n d neither isany a r c h a e o l o g i c a l site. T h e A b b o t s t o n esite is part of a wider archaeologicallandscape of international i m p o r t a n c e .O t h e r archaeological sites in the vicinityare: t h e Stanway burial site ( 1 4 0 0 meast); Grymes Dyke ( 1 6 0 0 m east); a n dt h e late Iron A g e a n d R o m a n site atGosbecks, with its classical R o m a nt e m p l e a n d t h e a t r e (east of GrymesDyke). C a m u l o d u n u m had t w o centresof activity: Gosbecks, w h i c h was probably t h e site of king Cunobelin's f a r m stead, a n d Sheepen (near the presentday Colchester Institute), w h i c h wasp r e d o m i n a n t l y concerned with t r a d e a n dmanufacturing.C a m u l o d u n u m was d e f e n d e d by asystem of earthworks or dykes (see plan).T h e burial site at Stanway was actuallyoutside t h e defences o f C a m u l o d u n u m ,t h o u g h it was unquestionably linked to itsocially (and chronologically). Like Stanway, t h e A b b o t s t o n e site is also outsidet h e d e f e n d e d parts of C a m u l o d u n u m .T h e question t h e n is, to w h a t extent wast h e A b b o t s t o n e site actually part ofC a m u l o d u n u m ? A n o t h e r question is thed y n a m i c between native a n d R o m a nsettlement. Stanway was a native burialsite, a n d Gosbecks was a native sitew h i c h b e c a m e R o m a n i s e d . H o w doesthe A b b o t s t o n e site fit into this picture?Was it a native f a r m s t e a d w h i c h coexisted with Gosbecks a n d t h e n o u t lived it, or was it t a k e n over by R o m a nsettlers?4

Previous excavationsLike Stanway a n d Gosbecks, A b b o t s t o n ehas been k n o w n for s o m e t i m e as ac r o p m a r k site. Fieldwalking surveys (surface collections of objects) by t h e Trustin 1997 a n d 1 9 9 8 scanned areasbeyond the c r o p m a r k s , to check for previously u n k n o w n archaeological remains.We identified t h i n spreads of prehistoricflints a n d R o m a n brick a n d tile, with at h i n c o n c e n t r a t i o n of R o m a n brick a n dtile directly north of t h e c r o p m a r k site.Surprisingly there was no surface material over the c r o p m a r k itself. T h e Trustundertook a geophysical survey overthe cropmarks in 1998 w h i c h failed toestablish the location of a r c h a e o l o g i c a lfeatures below the ploughsoil, possiblybecause t h e g r o u n d was t o o wet. T h ec r o p m a r k site was extensively trialtrenched by t h e Trust in early 1 9 9 9 . Thisat last pinpointed t h e surviving subsoilfeatures, thereby identifying t h e areaswhere full-scale archaeological excavation should be carried out.The Trust's excavation in 1 9 9 9 showedt h a t t h e earliest activity here is represented by a few worked flints of probablelate Neolithic or Bronze A g e date. T h eearliest i m p o r t a n t f e a t u r e was a ditchdefining a roughly circular enclosure - apotential prehistoric house site. Therewas no sign of t h e post-holes w h i c hm i g h t show the position of a roundhouse, but the excavation of t h e ditchproduced M i d d l e Iron A g e pottery w h i c hconfirmed its prehistoric d a t e (see m a g azine no 1 3).The Trust excavation t e a m returned toexcavate the rest of the site late in 2 0 0 0 ,but the very wet ground conditions prevented m u c h digging, and the season hadto be c a n c e l l e d .2 0 0 1 excavationThis year's task was to c o m p l e t e t h eexcavation of t h e r e m a i n d e r of t h e largeR o m a n enclosure. This was no m e a ntask - standing water had to be p u m p e do u t of all the features, a n d the site had tobe scraped clean by m a c h i n e to removet h e silts w h i c h had washed o n t o t h e siteover t h e winter. T h e m a i n results havebeen the discovery of m a n y m o r e ditchlines t h a n were visible on t h e airp h o t o g r a p h s or were expected after theprevious season of d i g g i n g . A h u m a nskull was f o u n d , with s o m e brokenpottery, in a Late Iron A g e d i t c h near t h eM i d d l e Iron A g e enclosure (see picture).T h e lower jaw was missing, suggestingt h a t t h e skull had been placed herew h e n already d e c o m p o s e d . T h e skullm a y be t h e remains of a burial orperhaps a ritual deposit.FarmingIt w o u l d appear t h a t there was a g a p inactivity on the site until the late Iron A g e ,w h e n ditches were cut to define a largeenclosure. In f a c t the majority of thefeatures on the site were ditches definingthree large enclosures - first the IronA g e o n e m e n t i o n e d above, a n d thent w o separate R o m a n enclosures (northa n d south). T h e joint life-time of theenclosures spanned the later Iron Age tot h e m i d 3rd century A D . The north (andlarger) R o m a n enclosure had smallerditches or gullies splitting it into smallerpaddocks or fields, a n d other parallelditches m a r k i n g o u t road lines whichwere originally m e t a l l e d . There wereseveral c r e m a t i o n burials, o n e of t h e man interesting post-burial (where ac r e m a t i o n had been placed in a deeppost-hole w h i c h presumably held a largepost to m a r k t h e spot). W h a t was mostintriguing a b o u t t h e first season's workwas t h e c o m p l e t e absence of buildings.T h e r e m a i n i n g part of the ditch a r o u n dt h e house site was excavated, a n d(gratifyingly) a ring of post-holes wasdiscovered. These define t h e site of aprehistoric structure (presumably a house)on this spot. T h e internal d i a m e t e r of t h epost-hole ring was a p p r o x i m a t e l y 1 0 m ,so w i t h a c o n v e n t i o n a l t h a t c h e d roofo v e r - h a n g i n g this post-hole ring, t h estructure m i g h t have been closer toa p p r o x i m a t e l y 1 4 m external d i a m e t e r by no m e a n s a small building (seepictures).A b o v e : Ben Holloway uncoveringthe h u m a n skull.Left: plan of C a m u l o d u n u m .Opposite page T o p : sketch of a M i d d l e Iron A g eround-house.B o t t o m : the t e a m m a r k i n g thepositions of the eleven post-holesof t h e M i d d l e Iron A g e roundhouse.5

There was a short stretch of possiblebeam-slot associated with the postburial, but no other structural features ata l l . T h e southern (and smaller) R o m a nenclosure was equally i n t r i g u i n g . It hadopposed entrances, t h e northern o n ehaving a pair of gate-posts set back f r o mt h e d i t c h line, w h i c h w o u l d imply theexistence of an internal bank with t h eg a t e between t h e ends of t h e bank.Still describing t h e site as a series ofenclosures, it is now possible to suggesta sequence of d e v e l o p m e n t . T h e earliestenclosure seems to have developed o u tof t h e circular Iron A g e house site, a n dto have been a d d e d to progressively,until the enclosure was regularised bybeing recut in t h e R o m a n period as o u rnorth enclosure. T h e south enclosurewas a d d e d later o n , also in t h e R o m a nperiod. Some of t h e ditch lines areboundaries f r o m a n a d j a c e n t fieldsystem w h i c h join up with the enclosureditches, a n d r e m i n d us t h a t the site waspart of a wider f a r m e d landscape.Above: lines were paint-sprayed on t h eg r o u n d t o outline t h e archaeologicalfeatures as they were uncovered bym a c h i n e . Parts of t h e features were t h e nh a n d - d u g so t h a t we could d a t e t h e m ,explore their physical characteristics,a n d recover environmental m a t e r i a l .Given t h a t t h e site was o c c u p i e d f r o mthe late Iron A g e to the mid 3rd century,the question of t h e location of the livingareas t h e n arises. T h e Iron A g e r o u n d house is an obvious focus for o c c u p a t i o n a t t h a t t i m e , but w h a t a b o u t theR o m a n period?

Perhaps these finds occurhere as d u m p e d rubbish, having beentransported f r o m somewhere else.A b b o t s t o n e is a" site where we c a n n o tc o m e up with all the answers. However,t h e enclosures are part of a late Iron A g ea n d mainly R o m a n rural site concernedprincipally with f a r m i n g . If R o m a n buildings were erected here, they have notsurvived.W h a t a b o u t t h e inhabitants? It is difficultto see a radical c h a n g e between the IronA g e enclosure a n d t h e R o m a n enclosures, so there is no basis for a r g u i n g forR o m a n settlers c o m i n g in to live on anIron A g e site (there is a lack of highstatus finds like coins a n d evidence ofbuildings). In fact, t h e lack of rich findsa n d the a l m o s t total absence of metalfinds m i g h t indicate t h a t it c o n t i n u e das a native (British) site w h i c h neverb e c a m e a R o m a n villa, a n d was neverlived in by well-to-do Romano-Britons.To take a different a n g l e , perhaps thelack of buildings is a reflection of the factt h a t the people w h o f a r m e d here did notnecessarily live here. Perhaps t h e sitewas o w n e d by absentee landlords, w h oused a t e a m of locals to w o r k t h e landhere, a n d perhaps even those workerslived off site.The excavations at Abbotstone werefunded by T a r m a c Quarry ProductsLtd.

Salt of the earth!Salt is o n e of life's necessities. Before thediscovery of the inland sources of salt inCheshire a n d Warwickshire w h i c h stillsupply us today, salt was producedmainly by distillation of sea water atcoastal sites. There is evidence for prehistoric salt-production at M u c k i n g a n dFenn Creek ( W o o d h a m Ferrers) in Essex,but the best evidence is f r o m t h e lateIron A g e a n d R o m a n period w h e n over3 0 0 salt-making sites are k n o w n f r o mEssex alone. These sites are called 'redhills', because they survive to this day aslow red m o u n d s at approximately highwater mark.These curious sites have attracteda n t i q u a r i a n a n d archaeological interestfor some t i m e . In days g o n e by, theywere t h o u g h t to be Saxon or Danishpotteries, R o m a n brickyards, or c a m p sites used by q u e e n Boudica or Alfredthe Great w h e n he was hiding f r o m theDanes. Organised research dates backto 1 8 7 9 , but t o o k on fresh impetus in1906 with t h e f o r m a t i o n of t h e Red HillsExploration C o m m i t t e e w h i c h d u g a tvarious red hill sites in L a n g e n h o e a n dHullbridge. In recent years, Kay deBrisay was t h e m a i n motivating force inred hill research, d i g g i n g sites in M a l d o nand Peldon.W h e n the Essex Wildlife Trust applied forconsent to create a wildlife sanctuaryby breaking t h e sea wall at GreatW i g b o r o u g h t o allow m a n a g e d retreatof the coastline by t h e sea, this affectedseveral red hill sites. T h e Trust wasGreat Wigboroughcontracted by the Wildlife Trust to fieldwalk the site a n d then test-trench anyconcentrations of material. The fieldwalk revealed several surface c o n c e n t rations (see chart) of R o m a n pottery a n d' b r i q u e t a g e ' , t h e debris f r o m salt m a n u facture.

RomanColchester'swestern suburbT h e planned redevelopment of theSt Mary's hospital site presents achance to explore part of a largeRoman suburb outside the BalkerneG a t e . T h e nature of the archaeologicalremains can be predicted to a degree,because of the major excavation of the1 9 7 0 s on the Balkerne Lane siteimmediately to the south. And there isan old, undocumented plan showingw h a t appears to be the remains of aRoman temple on the St Mary'shospital site itself.Like t h e m o d e r n t o w n , the R o m a n t o w nof Colchester had suburbs outside t h et o w n wall. A large part of the westernsuburbs were excavated by t h e Trust inthe 1970s before t h e construction ofSt Mary's multi-storey car park onBalkerne Hill. As a result, it was possibleto trace the d e v e l o p m e n t of the areaimmediately south of t h e site of t h eformer St Mary's hospital f r o m t h e mid1st century o n w a r d s .The g r o w t h of t h e suburb reflects t h eg r o w t h of the R o m a n fortress a n d t o w nlying to the west. W i t h i n a few years ofthe R o m a n conquest o f A D 4 3 , a g r o u pof flimsy buildings, perhaps workshops,had been erected outside t h e westgate of the R o m a n fort. By the t i m e ofthe Boudican revolt o f A D 6 0 / 1 , m o r esturdy-looking buildings had t a k e n theirplace, lining each side of the L o n d o nroad w h i c h now passed t h r o u g h t h e freestanding t r i u m p h a l arch (on the site ofBalkerne Gate). These were presumablyshops a n d workshops providing serviceindustries to the t o w n . After the revolt, inthe period A D 8 0 - 1 0 0 , the inhabitantsand shop-keepers in the western suburbmust have felt they d i d n ' t fit in in t h equite the same way as before, becausethe R o m a n t o w n wall had now beenerected - a physical barrier between t h esuburbs a n d t h e t o w n , w h i c h incorporated the previous free-standing archwayand converted it into t h e west g a t e of thet o w n . A Romano-Celtic t e m p l e was alsobuilt
