Boxford Open Day 2019

Cotswold Archaeology are pleased to have been working with the Boxford History Project on further excavations at the Mud Hole Roman Villa site. Following the discovery in 2017 of the a very rare mosaic featuring scenes from Greek Mythology, the community group raised enough funds to allow another season of excavation, which has just come to an end.

On Saturday 31 August we supported an open day at the site and were astounded by the numbers of visitors and the very real enthusiasm and interest in the site. Around 3,000 people turned out on the day to see the site, listen to the site team explain what had been found and have a look at some of the artefacts recovered.

While the focus of the excavations this year has been on revealing and recording the full mosaic floor, there were a number of other research questions that we were keen to resolve. The investigations have explored the origins of the structure, sought to determine whether further mosaics might have been present and tried to understand the later history of the building and its use.

The results have been astounding. Further elements of the imagery on the mosaic have been revealed, showing a greater array of tales from Greek Mythology. We also now have a much better understanding of the building’s construction, evidence to suggest that no other mosaic floors were present and evidence of alterations and repair late in the building’s life. There is a wide range of material that now needs further detailed investigation and analysis before we can tell the full story. We look forward to sharing this with you when the work is complete!

The fall and rise of a medieval farm in the Severn vale

Fieldwork discoveries

Recent excavation by Cotswold Archaeology’s fieldwork team revealed the remains of a medieval farm on the flat clayland of the Severn vale.

Post-excavation analysis

Now that fieldwork has finished, the project has passed to our post-excavation team who are preparing an assessment report. The report will map a route leading to full analysis and publication of the findings, and the deposition of the archive at an appropriate museum, where it will be available for future research.

Dispersed medieval settlement

By the 11th century, the familiar English nucleated village landscape had already evolved across much of the country, but other areas, including the Severn vale, were still characterised by a dispersed settlement pattern of individual farms and small hamlets. These settlements occupied a landscape of woodland, which had regenerated since the end of the Roman administration, interspersed with clearings for grazing and small farms, including the current example. Although the differences were not absolute, such wood-pasture areas would have stood in contrast to the more open sheep-corn landscapes with their nucleated villages in areas such as the Cotswold uplands, and it has often been commented that the occupants of these different pays would have held differing mentalities.

Medieval bones, modern research

The farm was probably family-sized, although it should be remembered that slavery was still practiced, albeit at a reduced level, into the 12th century and villeinage (the English legal term for serfdom) into the 17th century, and so over its lifetime the farm may have been occupied by an extended family as well as slaves and villeins. Although such farms were probably very common, few have been excavated, making this an exciting discovery and one to which modern forms of analysis can be applied, including isotope analysis of the animal bone assemblage, which can examine chemical traces in bones and teeth in order to estimate whether, for example, the animals were grazed locally on floodplains.

Most of the finds from the site comprised sherds of locally produced pottery known as Gloucester TF41B, dateable to the mid 11th to mid 13th centuries. A dump of this material was found within a ditch belonging to the medieval farm and analysis will aim to determine whether this represents ‘wasters’ from a local kiln thought to have operated nearby but yet to be discovered.

Agrarian crisis, plague and abandonment

The farm seems to have been abandoned around the 13th/14th century. An obvious hypothesis to test during our analysis is whether the site was a victim of the early 14th-century agrarian crisis which was responsible for many of the shrunken and deserted villages whose remains can be detected from surviving earthworks in the landscape. Intriguingly, the site also contained the remains of a single individual laid in a grave. The remains of this person were very poorly preserved and we do not yet know their date. Radiocarbon dating may indicate whether this was someone associated with an as-yet unidentified Roman or early post-Roman farm, or someone from the medieval farm itself, conceivably even a victim of the 1348–9 Black Death.

New money

One of the questions we will seek to address is how long the site remained abandoned for (if indeed it ever was fully abandoned). It was certainly reclaimed, since a large ring-ditch was built over some of the earlier medieval enclosures. No structural remains were found, and one possibility is that this was a mound for a windmill, but another is that t this may have been a moat surrounding the house of a wealthy peasant with aspirations to grandeur. Although the crises of the 14th century had brought misery to many, for those who survived there were opportunities to make money; the economy was increasingly market orientated, whilst with a reduced population, labour was in higher demand. Did the moat surround the residence of a peasant on the up? To the modern mind, moats are conceptually associated with castles, but in fact the majority surrounded far more modest dwellings, including those of the lesser gentry and wealthier peasants, both of whom could be regarded in modern terms as ‘new money’. As well as providing an obvious status symbol and security, recent research suggests that moats were amongst a suite of features used in medieval architecture to restrict access to certain areas to individuals thought to be of appropriate status, itself an expression of power and a reflection of the structure of later medieval society.

The moat may have fallen out of use by the 16th century and does not appear on any of the historic mapping so far examined, but investigation will examine whether its decline was associated with the enclosure of the site for sheep pasture as part of the rise of the Gloucestershire woollen industry.

A Bronze Age Cremation Cemetery and Other Prehistoric and Medieval Discoveries on the A477 Road Replacement Scheme, Carmarthenshire

Linear schemes such as road construction can transect large areas of land and so provide exciting opportunities for archaeological discoveries, and in this respect the archaeological investigations in advance of the A477 road improvements between Red Roses and St Clears in Carmarthenshire did not disappoint. Funded by the Welsh Government and facilitated by Ramboll, a programme of planning, survey, evaluation and excavation along the 9.5km length of the scheme identified numerous and varied evidence of past human activities dating from the Mesolithic through to the medieval period. The majority of this activity dated to the Neolithic and Bronze Age periods and included a significant Early Bronze Age cremation cemetery.

Details about these discoveries have been published this month in our most recent book (Cotswold Archaeology monograph No. 12), The Prehistoric Archaeology of the A477 St Clears to Red Roses Road Improvement Scheme 2012, by Alistair Barber, Alan Hardy and Andrew Mudd (Cotswold Archaeology monograph No. 12).

The factors that affect the outcome of archaeological investigations on linear developments such as the A477 road scheme are well known. The area available for investigation is limited to the narrow width of the development, and projects such as this one often pass across undeveloped and sometimes remote tracts of land where little previous investigation has taken place, and it is harder under these circumstances to envisage how the activity encountered sits within the landscapes of the past.

Although these factors certainly applied to the A477 road scheme, a great deal has been gained from the analysis of our discoveries along the corridor of road development. Interpretation of the prehistoric evidence has considerably benefited from the recent archaeological investigations during the construction of the Milford Haven to Aberdulais gas pipeline replacement, a stretch of which bisects the A477. In 2006 these pipeline works uncovered evidence for a prehistoric landscape of some significance, including the Class II Neolithic Henge lying some 225m to the south of the A477 road redevelopment at Vaynor Farm (PDF 7.7 MB). The knowledge gained from investigation of this earthwork, which probably remained visible in the landscape throughout the later prehistoric period, has enriched our interpretation and understanding of the archaeological remains along this stretch of the A477 development corridor.

Three locations along the road scheme were notable for the evidence of Mesolithic activity they revealed (Sites 25, 26 and 35). At Site 25 north of the town of Llanddowror a large concentration of flints and a posthole dated by a radiocarbon sample to the late Mesolithic suggest substantial use of the location. The site was on the floodplain of the River Taf, and no doubt favoured by those who used it for its easy access to a range of habitats and their natural resources. Early Neolithic evidence is also present here and hints at continuity, charred seeds and charcoal found in pits suggests the local woodland had been partially cleared for settlement, arable cultivation and possibly pasture. Transient Mesolithic activity was also indicated along the A477 road scheme to the west of Llanddowror at Sites 26 and 35 where small scatters of Mesolithic flakes and microblades were retrieved from the interface between the ploughsoil and underlying natural substrate.

A substantial Neolithic presence was identified at Site 37, east of Rhosgoch, Llanddowror, where postholes, pits, hearths and pottery provide rare evidence for domestic use. The site is also notable for the nature of the fills of some of the pits which were rich in finds including worked flints, whole (but broken) pots and burnt grain suggesting the deliberate placement of material in the pits.

An interesting aspect of the prehistoric remains from the road scheme was an apparent lack of activity that can be ascribed to the middle or Late Neolithic periods. This may be explained by shifting patterns of settlement, but we may also consider the possibility that the Neolithic henge at Vaynor influenced patterns of activity in the area, creating a tradition for ceremony rather than settlement that persisted into later periods.

In the section of the road scheme that ran close to the henge, traces of a Bronze Age barrow were discovered, together with a swathe of cremation burials and the site of pyres (Sites 18, 19 and 26).

These remains have benefited from in-depth analysis, from which an interpretation of the funerary monuments has emerged. Bayesian modelling of the radiocarbon dates by Frances Healy has enabled events to be modelled with a greater precision than would otherwise have been possible, and has also allowed a subtle chronological modelling of the activity within the barrow area in relation to the adjacent pyre site and surrounding features. The dates indicate a period from approximately 2000 BC to 1650 BC during which the burials took place.

With 38 deposits of human bone found in their primary locations, and further deposits in residual contexts, there were opportunities here to study the varied and variable nature of burial practices at this time and to compare this evidence with contemporary published data. Analysis of the human remains revealed that even the most ‘complete’ of the cremations did not represent a complete individual, even where the deposit has survived intact. Some cremations were contained within pottery urns, inverted or upright, or associated with empty vessels (accessory vessels) within the same grave pit (see below).

Some cremations were buried alone in grave pits or stone-lined graves (cists), and many pottery vessels appeared to have been buried without accompanying cremated remains. A number of the excavated features can be understood as the physical remains of aspects of ritual performances taking place on the site that may not have always included the act of cremation.

Another notable prehistoric site revealed by the road scheme investigation was the burnt mound located towards the western end of the road scheme at Site 32 near Red Roses. The mound, which was located adjacent to a watercourse, was composed of a mix of dark grey sandy silt, charcoal and burnt stone measuring approximately 15m long by 12.5m wide (see below). It was associated with two trough-shaped pits that may have held water. The purpose of these burnt mound sites remains obscure, but the most common theories are that these were used for cooking or were sauna sites.

Many of the undated features excavated along the length of the road scheme have been assigned to the prehistoric period based on similarities in fills and form, and the overall impression is of a landscape more heavily utilised in the prehistoric than later periods.

Archaeological evidence for activity along the road corridor of a date later than the Bronze Age was sporadic. Evidence for Roman activity was extremely sparse, but there was some dating from the medieval and post-medieval periods. Just to the south-east of St Clears lies the earthworks of Dolgarn Moated Site (Scheduled Monument CM 252), which was visible as a rectangular enclosure measuring 60m by 50m, defined by a ditch surrounding a slightly raised platform, and cut through by the old Turnpike road. The route of the new road crossed the south-eastern corner of the earthworks, providing an opportunity to excavate the ditch and a small part of the internal platform. Excavation showed the internal platform to be composed of horizontal deposits; these contained no dating evidence but were probably derived from the soil dug during the ditch’s construction.

The earthwork ditch proved to be 6.5m wide and 1.6m deep with a u-shaped profile. From one of the earliest of the ditch fills a carbonised seed was radiocarbon dated to cal. AD 1059–1263 (SUERC-50312). The fill above this produced 13 sherds of medieval pottery, 12 of these from a single vessel, almost certainly of locally made Llanstephan ware, dateable to the 13th to 14th centuries AD. All the pottery recovered from the later fills dates to the 13th to 15th centuries, and the absence of later material suggests that the monument was abandoned in the 15th century.

The analysis of a well-preserved assemblage of waterlogged insect, pollen and plant remains from the sequence of fills suggests that the ditch originally contained clear running water, although the levels of this had fluctuated, and that the immediate environs comprised a mixture of cultivated ground and pasture; the presence of dung beetles indicative of grazing animals nearby. As the ditch silted up the water within it had become murkier, and a decline in certain insect species indicates that there was less grazing nearby.

Dyfed Archaeological Trust Historic Environment Record (DATPRN 3884) suggested the Iron Age, Roman or medieval periods as possible dates for the monument, which had not been professionally excavated before.

Although earlier origins cannot be discounted, our investigations would suggest that the monument in its surviving form is a medieval construction.

Approximately 0.7km north of Red Roses, at Eglwyscumm, a cluster of ditches and robbed out foundation trenches indicate the location of a farmstead (Site 31), comprising at least two rectangular houses and one circular structure situated close to the buildings, with a network of associated paddock and field ditches extending to the south-east. The farm was only partially revealed within the road corridor, and clearly extended beyond the excavated area. Pottery from the features gave a date range of the 13th to the 14th centuries AD. An assemblage of charred plant remains from the ditch of the circular structure provided information on diet, crop-processing and the local environment of the farmstead.

No other sites of medieval occupation were identified although a number of pits and ‘ovens’ were found; the latter, distinguished by scorched bases and abundant charcoal deposits, are likely to have been used to dry cereals at the edges of the fields within which they were grown, prior to transportation for storage within farms or villages. Radiocarbon dates from carbonised organic remains dated most of these features to within the 11th to 13th centuries, with two earlier pits dated to the 4th to 6th and 9th to 11th centuries respectively.

A report on these medieval excavations, and a summary of the prehistoric discoveries will be published in the journal Archaeology in Wales (Hart and Alexander forthcoming).

Quern stone from Hinkley

In 2012/2014 Cotswold Archaeology excavated a late prehistoric and Romano-British settlement site at Hinkley Point, Somerset. One of the many artefacts discovered was a complete upper stone from a rotary quern, which is the subject of a recent online publication by Dr Ruth Shaffrey – The Movement of Ideas in Late Iron Age and Early Roman Britain: An Imported Rotary Quern Design in South-Western England.

Quern stone under excavationThe quern stone has a projecting socket for a vertical handle and thin-section analysis has revealed that it was made locally, in Somerset.

The object is remarkable for being the earliest dated example of a quern of this form so far found in England. It is also the first example ever found in southern England; querns with horizontal handles were more typically used in this region during the late Iron Age and early Roman period. As the quern stone was produced locally, the design appears to have imitated styles more popular elsewhere. This type of quern was common in Germany during the late Iron Age and early Roman period, although broadly similar styles of rotary querns are also found in north-eastern Ireland and south-western Scotland.

Ruth’s fascinating online First View publication is available on Cambridge Core.

A multi-million pound Thames Water project to protect the future of a rare Oxfordshire chalk stream has revealed some fascinating and gruesome discoveries dating back almost 3,000 years. The excavation, led by CA’s Project Officer Paolo Guarino revealed an ancient settlement containing an array of historic artefacts. Among the important finds were 26 human skeletons believed to be from the Iron Age and Roman periods, and some likely to have been involved in ritual burials, along with evidence of dwellings, animal carcasses and household items including pottery, cutting implements and a decorative comb.

Our CEO Neil Holbrook, said: “The new Thames Water pipeline provided us with an opportunity to examine a number of previously unknown archaeological sites. The Iron Age site at Childrey Warren was particularly fascinating as it provided a glimpse into the beliefs and superstitions of people living in Oxfordshire before the Roman conquest. Evidence elsewhere suggests that burials in pits might have involved human sacrifice. The discovery challenges our perceptions about the past, and invites us to try to understand the beliefs of people who lived and died more than 2,000 years ago. We’ve had a tremendous reaction to this discovery on social media with people wondering just what was going on here – see what people have been saying at our Facebook post.”

Project Officer Paolo added: “These findings open a unique window into the lives and deaths of communities we often know only for their monumental buildings, such as hillforts or the Uffington White Horse. The results from the analysis of the artefacts, animal bones, the human skeletons and the soil samples will help us add some important information to the history of the communities that occupied these lands so many years ago.”

Cotswold Archaeology has now carefully removed the items for examination, allowing Thames Water to start laying the six kilometre pipe which, following consultation with residents, will supply nearby villages with water taken from groundwater boreholes near the River Thames and not Letcombe Brook. The archaeological findings have already been shared with residents at events in Letcombe Bassett and Letcombe Regis village halls.

Rough Justice in Saxon and Norman Hampshire?

When many people think about archaeology they focus on amazing new discoveries which are totally unexpected – that’s the exciting bit, right? Of course this is part of the romance of archaeology, but it poses a conundrum with modern commercial archaeology as significant and unexpected finds are what developers want least: they hold up the builders and can be expensive to deal with. Consequently much of the work of Cotswold Archaeology is, to use contemporary jargon, associated with de-risking proposed developments (i.e. avoid surprises when the construction work begins). But despite archaeologists’ best endeavours the old adage that you never know what’s under the ground still holds true, as a recent example at the site of a new Aldi supermarket in Andover, Hampshire, shows very clearly. Here a routine watching brief made a most unexpected discovery, but thanks to the generosity and genuine interest of Aldi this story has a highly satisfactory ending.

Archaeologist excavate human remains on Wenhill siteDuring the watching brief human remains began to be found, laid in graves dug into the natural chalk. In all 124 bodies were revealed, but what was even more surprising is that most were of young men and a number had injuries that clearly showed that they had been executed. Radiocarbon dating demonstrates that the cemetery was in use between c.AD 900 and 1300, and we conclude that this was an execution cemetery established in the Saxon period, but which carried on in use after the Norman Conquest. Perhaps the cemetery lay near a gallows where public hangings and executions took place? In the past justice could be harsh and summarily delivered; we will never know the perceived crimes the individuals buried here were judged to have been guilty of (although history tells us that some might seem by modern standards to have been trivial misdemeanours). This amazing discovery provides a fascinating window onto crime and punishment in this formative period of English history; find out more at Weyhil, Andover – an Anglo-Norman execution.

Fully excavated graveThis highlight brings us up to date and we’ve now selected one great project for each of the thirty years of our existence. The Andover dig is a great way to mark Cotswold Archaeology’s 30th birthday which fell on 17 March. If the archaeology we investigate in the coming decades is anywhere near as good as that which we have done over the last thirty years, then being an archaeologist with us in the coming years will be a great career choice.
