A Roman site at Llanwern, South Wales

Between September 2019 and January 2020, Cotswold Archaeology undertook an excavation at Llanwern in South Wales on behalf of RPS Planning and Development and Redrow, on a site occupying the east face of a hill overlooking the Gwent Levels.

The investigations revealed a complex including several stone-founded Roman buildings, terraced into the hillside. These included two stone-built circular buildings, a rectangular structure and an apsidal structure, with evidence for activity between the 2nd and 4th centuries AD. At least three other buildings were represented by partial ring-ditches, one containing a kiln or oven. Environmental samples taken from the oven may allow its function to be determined.

The rectangular structure, which measured 17m long and 7m wide, appears to have been the main building at the site. It had been subject to at least three phases of modification over time. The western side of the building had been cut into the terrace, with made ground to the east used to provide a level construction surface for the structure’s eastern extent. Two areas of mosaic flooring were identified, possibly representing a room and an associated corridor, which had potentially been separated by a wooden partition wall. The mosaics have been dated on stylistic grounds to the 4th century AD.

The function of the rectangular building is currently uncertain, although a complex series of stone-lined culverts drained water from a group of springheads at the west of the site down to the east, indicate that water-management played an important role in the use of the site. Many finds were recovered, including large quantities of Roman pottery, animal bone, ceramic building material (including tile), brooches and coins. The presence of unusual plate brooches amongst the assemblage raise questions as to whether the complex may have had a religious focus. One of the tile fragments bears the stamp of the Roman military unit Legio II Augusta, which was stationed at nearby Caerleon, suggesting a possible connection between the sites.

To the immediate north of the rectangular building, an impressive and well-constructed east-west aligned metalled trackway was formed from large unworked limestone blocks; the trackway measured at least 50m long and 4.8m wide, with its size and method of construction suggestive of a high volume of traffic.

At the west end of the site, an apsidal structure was terraced into the hillside; the internal area of the structure contained natural stone that had been exposed to create an area of hard standing, with a surface constructed on top, presumably for extra consolidation. The function of the structure is currently uncertain; interpretative possibilities being considered include a nymphaeum, a church, a shrine or possibly even a theatre, which utilised the slope as a spectator area.

This structure abutted a heavily truncated rectangular building, which contained a cremation burial and an inhumation burial. The latter burial had been placed in a prone (face-down) position. These burials raise the possibility that this building formed part of a mausoleum.

Other features identified at the site include an area of metalworking, water tanks and features interpreted as possible quarry pits.

It is hoped that analysis during the post-excavation stage will allow questions about some of the unusual aspects of the site to be answered.

Weyhill Medieval Punishment Cemetery – Monograph Release

Following four years of hard work across all our teams, CA has just published a monograph on the medieval punishment cemetery discovered in Hampshire.

Weyhill cemetery monograph coverIn 2016, a watching brief in advance of construction at a site between Andover and Weyhill revealed disturbed human remains. This formerly isolated roadside location, which had been partly developed in the later 20th century, lies close to the historical boundary between Andover and Abbotts Ann Hundred. The discovery led to the excavation of a densely crowded group of partly disturbed and heavily intercut graves, and it soon became clear that this was not a normal community cemetery. The remains of some 124 individuals, mostly male and adult, were revealed, with much additional disarticulated bone. Many had clearly been buried with their hands tied behind their backs or had been interred face-down, and some had been decapitated.

As might be expected with a rural ‘execution’ (or punishment) cemetery of this type, very few artefacts were recovered. In this case only one find, a silver penny dateable to AD 979-985, allowed close dating, which suggested that the site was a distinctive type of Saxon cemetery known elsewhere in Hampshire. However, radiocarbon dates from articulated burials, selected for their spatial and stratigraphic positions, demonstrate that the cemetery was in use from at least the 10th century (and possibly as early as the 8th century), and continued in use beyond the Norman Conquest to at least the 13th and possibly the 14th century. Stable isotope analysis shows that the people buried here were mostly of local origin.

The significance of the site lies in this evidence for continuity, at a local level, of the organisation of judicial power from Saxon times well into the Middle Ages. It is the first site to provide clear evidence for such duration of a ‘punishment’ cemetery.

Cotswold Archaeology Wins Prestigious Book of the Year Award!

The 12th annual Current Archaeology Awards were held on Friday 28th February at Senate House in London, and we are very pleased to announce that our collaborative book, Life and Death in the Countryside of Roman Britain, won the award for Book of the Year!

Life and Death in the Countryside of Roman BritainThe book is the third and final volume in the ‘New Visions of the Countryside of Roman Britain’ series; it deals with the rural people of Roman Britain…how they looked, lived, worshiped, died, and how they were treated in death. Cotswold Archaeology was a major partner in this hugely successful Leverhulme Trust funded project, along with the University of Reading, the Archaeology Data Service and Historic England. CA’s Neil Holbrook acted as a series editor for the volumes, and the volume was co-authored by our very own Tom Brindle (Post-Excavation Manager). More information about the project is available on the ADS website, where you can download a free PDF of volume 1 in the series, and access the online database.

A review of the book was published in the January 2019 edition (no. 347) of Current Archaeology, and the volume can be purchased from Oxbow Books.

2020 is CA’s most successful year so far at the awards, with our first win to date and a record three nominations in total. CA’s two other nominations were also for collaborative projects, with Revealing Boxford’s Ancient Heritage nominated for Research Project of the Year, and Exercise Shallow Grave up for Rescue Project of the Year.

Congratulations to all of the award winners!

Keynes, trains and automobiles

We were clearly trying too hard to come up with a witty headline but the facts are clear, when it comes to the big infrastructure projects we stand side-by-side with our clients, managing their complex archaeological requirements. Whether it is in the planning or construction stages of projects, we have the skills and experience to handle the scheme specific logistical tests that invariably accompany the more traditional archaeological challenges. The last few years has seen the Milton Keynes team busy working on significant energy, airport, road and rail infrastructure projects across central and eastern England.

During the late summer of 2019, while working on a highway scheme in Hertfordshire, our team topped 50 archaeologists on site. While, by most measures, this has to be acknowledged as a large archaeological project, in this instance the significance was not the scale but the unique circumstance that we had colleagues from all of our five offices working alongside each other. One company; one high standard; one large talent pool to draw from.

But energy and transport projects don’t have the monopoly on scale; we have been working on some seriously large-scale strategic housing schemes too. Several different five-hundred plus trial trenching projects in Northants, Leicestershire, Rugby and Essex have kept our teams occupied. At Rugby, we are nearing our 10th anniversary working together with the client team; with more site work planned for later this Spring.

These longer running, sustainable urban extension projects present a different set of challenges such continuity of personnel, retaining invested-knowledge and keeping the momentum going on post-excavation work and publications; all matters that we are well-versed with. In the next few weeks we are looking forward to returning to Bidwell West, Central Beds; another large-scale strategic housing scheme that we have been working on for several years.

A moated site near Tewkesbury, Gloucestershire

Last autumn, the CA field team excavated a moated site near Tewkesbury, Gloucestershire. The moat had largely been infilled during the late 20th century, while post-medieval domestic buildings within the interior were demolished following a fire in 2005. The moat is now surrounded by a large industrial estate and business park, although it originally occupied a rural location. Despite this, it was deeply stratified, requiring three phases of mechanical stripping.

At the west of the site, the first site strip identified the later moat fills as well as the 18th and 19th-century domestic structures, all of which correlated closely with the available 19th-century cartographic evidence. Disappointingly, the moat here was relatively shallow, typically no more than 2m deep, and only 18th to 20th-century artefacts were recovered from within the four hand-excavated interventions.

The island created by the moat contained a number of later medieval/early post-medieval ditches and a stone culvert, which were clearly cut by the moat’s western arm before extending beyond the limit of the site. This suggested that the western part of the surviving moat was not medieval in origin, but possibly part of a much later formal landscaped garden, contemporaneous with the post-medieval buildings.

Outside the moat, immediately to the north, re-stripping revealed the footprint of a large medieval aisled barn. This stone building was very close to a post-medieval brick bridge across the moat’s northern arm, indicating that the building and the bridge were not contemporaneous. The stone barn was at least 35m long, 8m wide, and had eight surviving central stone post-pads within its interior. It had been roofed with Cotswold stone slates, although only the smaller pegged tiles survived.

Hand-excavation within the moat’s northern and eastern arms revealed a strikingly different sequence, and here it reached a depth of 3.5m. Organic-rich fills lay beneath the post-medieval deposits and, importantly, the earliest fills produced exclusively 12th to 14th-century pottery.

A bridge, contemporaneous with the medieval moat fills, was identified crossing the eastern arm, comprising interior and exterior stone abutments of finely dressed and coursed limestone. Two large, squared timbers (each 5m long and 0.4m square) were incorporated into the stonework, founded on the exposed natural clays at the moat’s base. Several upright timbers had been incorporated into the base timbers with mortice and tenon joints. While the interior stone abutment survived in good condition, the exterior stonework had suffered a catastrophic failure, which presumably rendered this bridge unusable.

The findings bring into question the true extent of the medieval moated site. It is now speculated that the original medieval moat enclosed a much larger area, probably extending west into an area truncated by modern flood alleviation works. This postulated part of the moat may have been truncated (or completely abandoned) when an early post-medieval mill race was constructed along the western limit of the site.  The surviving western arm is certainly much later (possibly 18th century) and runs parallel with the mill race; its most likely interpretation is as a post-medieval garden feature, albeit one that perhaps re-instated the dynamics and grandeur of a moated site.

Filming with Tern TV for Channel 4’s “Bone Detectives: Britain’s Buried Secrets”

In 2019, CA was contacted by the production company Tern TV, who had been commissioned to create a new series of programmes to be aired on Channel 4, specifically investigating the post-excavation side of sites where human remains had been found.

The cemetery CA excavated in 2016 at Weyhill in Andover was an ideal candidate. The site had all the elements needed for a TV programme.  There was a question to investigate – was this an execution cemetery? And we had a wealth of evidence with which to explore this question – scientific analysis using isotopes and radiocarbon dating had been undertaken, documentary sources exist, and of course we have the bones themselves.

CA osteoarchaeologist Sharon Clough had undertaken the analysis of the bones, so Tern TV asked Sharon to come into the studio and film with the series presenters, Tori Herridge and Carla Valentine. Project Officer Jeremy Clutterbuck, who had led the excavation, was invited to film on location in what is now a supermarket carpark. In fact, the hashtag #carparkdetectives became a theme during production of the series due to the number of sites which are now, or were once, carparks!

studio in BelfastThe studio was in Belfast, so Sharon was flown out to spend two and a half very long days filming in July, on what were some of the hottest days of the summer – with the baking weather and studio lights combined, it was unbearably hot! With little prior TV work (except for an episode of Time Team as a digger), this was a relatively new experience for Sharon, with a steep learning curve, although Tori and Carla were very supportive and helpful, as were the rest of the production company.

Taking part in the series provided a fantastic opportunity to present to the public the sobering story of this fantastic site, allowing it to reach a far wider audience than public lectures alone.

The episode will be broadcast on Channel 4 at 8PM on Saturday 25th January 2020 and will subsequently be available on Catch Up. We hope you enjoy the it – watch this space for news about our forthcoming book about the site!
