One of PCA’s archaeological excavation display boards has been used as a prime example of public dissemination in a piece by Norman Redhead of Greater Manchester Archaeological Advisory Service about ‘Research, Impact and Legacy’. The article, which features on P26 of the 2019 CIfA Year Book and Directory  ‘explores ways in which archaeologists can engage with the public and local societies in planning led archaeology’. The board for 74-88 Great Ancoats Street, Manchester (which can be viewed here) was created by PCA to provide a permanent display in the new building and details the findings from the 2016 excavation on behalf of Mulbery City.

New Monograph Out Now!

31st July 2019

We are pleased to announce that our latest publication in the OAPCA Thameslink Series is available to purchase today from the Publications page of our website.

The Thameslink Project provided the opportunity to investigate the archaeology of a broad swathe of the north island of Roman Southwark revealing details of the development and occupation of Roman Southwark’s north island including early clay and timber buildings, extensive burnt horizons, interpreted as the residues of the Boudican revolt and redevelopment, with many well-appointed new buildings constructed in stone. A substantial masonry bath house, largely preserved in situ and now scheduled, represents one of the most significant findings of the project.

This monograph, ‘ A Bath House, Settlement and Industry on Roman Southwark’s North Island: Excavations along the route of Thameslink Borough Viaduct and at London Bridge Station’, presents the archaeological sequence encountered, set alongside themed discussions which focus on aspects of the settlement’s development, chronology, infrastructure and economy, while specialist artefactual and ecofactual sections present the significant and extensive finds assemblages in detail.

CBA East Event - September 2019

The Council of British Archaeology in the East is holding an event to celebrate the CBA’s 75th Anniversary. It is on

Helpringham, Lincolnshire

Staff from the Newark office have been involved in carrying out historic building recording at Helpringham in Lincolnshire. Manor Farmhouse, the subject of the survey, is a listed building described in the citation as late 17th century, altered in the 19th century. However, there has been a lack of clarity with the dating and to address this a programme of dendrochronology was required.

Tree ring specialist, Robert Howard of the Nottingham Tree-Ring Dating Laboratory, visited the farmhouse and took a series of samples from various timbers in the building. Many of the examined timbers had sapwood, with several retaining full sapwood which allowed the tree felling dates to be identified. Several timbers in the roof were found to have the same felling date, 1704.

At first glance, comparing this to the suggested dating in the listed building citation, this may appear to indicate an early 18th century re-roofing of the building. However, the PCA staff undertaking the building recording identified a long-obscured datestone in the building – positioned high on the gable of the main range but covered over by an extension of probably late 18th-early 19th century date. This datestone is inscribed in Latin ‘MDCCV’ – 1705. The correspondence of this inscribed date with the chronology indicated by the tree-ring dating is a splendid validation of the accuracy of dendrochronology as a dating technique.

Cambridge Office News - June 2019

The time has come around again for PCA Cambridge to host four Sawston Village College Students for two weeks. This year, one week into their placement we accepted an extra two students as their placement was no longer able to host them. As usual we have put together a series of talks by various members of staff to give a flavour of the sort of work that archaeologists do and the skills and knowledge that are required. This includes stratigraphy, osteology, environmental sampling, finds illustration, GPS and CAD. We even managed to squeeze in a field trip to a local community dig which Mark Hinman (Director and Regional Manager) is directing in his free time!


On the 12th June a group of students from the local primary school came to visit PCA Cambridge excavations at Bawdsey, Suffolk, where they enjoyed a tour of the site from Supervisor Tom Revell. They also had a go at metal detecting with our resident metal detectorist Dave Curry! There will be a follow up talk from Sîan O’Neill at the school in the next couple of weeks.

Loves Farm Talk - St Neots Local History Society

Director and Regional Manager (Cambridge and Norwich) Mark Hinman spoke at Loves Farm House for the St Neots Local History Society about “The Archaeology of Loves Farm” on Friday 14th June. There was an attendance of approximately 100 residents, from which we have gained a new volunteer for the Cambridge office.

PCA Cambridge has made headway with the deposition of project archives in East Anglia over the past few months. Forty nine project archives from the Cambridge office and two from the Newark office were deposited with the Cambridge County Council Historic Environment Team (CCCHET). They will continue to deposit other projects in the near future.

Fulham Palace Opening

23rd May 2019

Last night, Director Chris Mayo and Post-excavation Manager Jon Butler attended a private view of Fulham Palace including the new museum, restored courtyard and garden to celebrate the completion of the restoration project. PCA was the archaeological contractor engaged for Stage 1 (2005-6) and Stage 2 (2010-11). We have also provided specialist support to Fulham Place since 2012 over the course of three community archaeology projects, and during the recent, final Stage 3 project.

The Stage 3 project has seen the creation of a new museum space which highlights the archaeology of the site and its fascinating garden history. PCA is delighted to be thanked on the museum’s walls. The extent of our work with the Palace is illustrated in the plan of investigations completed over the last 15 years.

Chris’ lasting memory of the enjoyable opening will be standing at the entrance to the Tudor courtyard and looking through the 15th -16th century gate and remembering the same view he photographed in October 2005 during our excavations as part of Stage 1. How times change.

The transformation work at Fulham Palace is a credit to the Trust, its dedicated team, and all who have worked tirelessly on the project. PCA is proud to have contributed, and we recommend that people pay a visit.

New Directors Appointed

May 2019

Succession planning is an important part of the life-cycle of most businesses and PCA is pleased to announce the creation of four new company Directors. These are being rolled out progressively over the next 6 months starting in May with Mark Hinman and Christopher Mayo, currently Regional Manager of the PCA Cambridge office and Project Manager at the PCA London office respectively, followed in three months by current Publications and Monographs Manager Victoria Ridgeway and three months after this by Helen Hawkins currently a Project Manager at the PCA London office. All four have demonstrable skills, and understanding of Pre-Construct Archaeology and its business ethos, and considerable enthusiasm for the challenges ahead. The ‘old-guard’, and remaining original Directors, Gary Brown, Josephine Brown and Peter Moore very much look forward to working alongside them.

Separately, and with immediate effect, Victoria Ridgeway has been appointed as the Company’s Head of Post-Excavation. Vicki has been with PCA since 1995, and has had a variety of post-excavation roles within it since 2004, and as such she is the ideal person to take on this role from Frank, with whom she is liaising closely to ensure a seamless switch from one to the other.

Resignation of Director

May 2019

After twenty one years of dedication and hard work on the Board of Pre-Construct Archaeology as well as fulfilling his key operational roles of being Head of Post-Excavation and Head of Health and Safety for the company Dr Frank Meddens has decided to step away from all such responsibilities and has resigned both from the Board and as Head of Post-Excavation.

The last few years have been particularly hard on Frank, with firstly being diagnosed with, and then successfully fighting off, a rare form of cancer for which treatment is still on-going, and, in February 2018, losing his beloved wife Beverley (Bev) after she succumbed to cancer, which itself was diagnosed at a time when she was supporting Frank through his own struggles. Inevitably these two major events, coupled with the stress of Directorial and Managerial responsibilities, have proved too onerous and Frank, after a year of quiet contemplation made the decision to step down.

However, stepping down does not mean stepping away as Frank will remain with PCA on a part-time basis as a contributor to the post-excavation team and will assist all PCA offices as required.

A Beaver Tooth from Winchester

A team from PCA’s Winchester office have been excavating at Barton Farm, on the northern edge of the Hampshire city, since January 2015. This exciting site has produced a remarkable array of archaeological finds, with large quantities of pottery, animal bone and other artefacts recovered from features dating from the Neolithic period through to the 19th century. But one recent find, a Beaver tooth (incisor), excavated from a pit dated to the later Neolithic or early Bronze Age (3000-1500 BC), has a been a particular talking point.

The Eurasian Beaver (Castor fiber), which was originally native to the UK, has been extinct in England for over 400 years, but these animals would once have been found across the country. Although relatively rare, artefactual evidence for the exploitation of Beavers, including teeth, bones and fragments of gnawed wood have been recovered from a number of prehistoric sites in Southern England, with particular concentrations recovered from wetland areas. Butchery marks on the bones show that beavers were used for their skins as well as their meat.

Interestingly, at Barton Farm, there was no sign of any other part of the beaver’s skeleton within the pit that produced the tooth, suggesting that just this item had been kept. It is unclear why the tooth was retained, but the piece, which is a striking, bright orange colour, something characteristic of the species, has unusual patterns of wear; a fact which has lead PCA’s archaeological animal bone specialist, Kevin Rielly, to suggest the item had perhaps been kept as either a keepsake or to be reused as an ornament or tool. Examples of such uses are known; Beaver incisors recovered from grave assemblages within Early Bronze Age barrows near Stonehenge, may have been selected for their ornamental value, whilst anthropological evidence indicates that beaver incisors can be hafted in to a handle for use as a woodworking tool.

Newcastle University Student Placements - 2019

Rowan and Ella joining pottery sherds from different contexts within the same pit

It has become a bit of a PCA tradition to host four Newcastle university students over the Easter vacation, in our London offices. This year we have been joined by Abbie, who is assisting with processing and sorting of environmental samples, and Ellie who has been recording details such as root etching on animal bones. We are also delighted to welcome Ella and Rowan to our new Chester-le-Street offices – they have been looking for (and finding) cross-context joins across a Roman pottery assemblage and sticking the pieces together. All are working really hard and hopefully enjoying their time with us too.

Look out for two more of our student placements in a couple of weeks’ time.

LAMAS 2019

Saturday the 16th March saw the 56th London and Middlesex Archaeological Society Conference, with an fabulous turn-out and full lecture hall. PCA were well represented this year with no less than three speakers, an exceptionally successful stand and bookstall, run by Vicki Ridgeway and Becky Haslam, and many staff turning out to provide support and enjoy the lectures.

Shane Maher opened the day with his excellent presentation on recent excavations at on the edge of the City at 56-62 Moorgate, with its complex sequence of Roman clay and timber buildings and tantalising hints of industrial activity. Later in the morning we were treated to Joe Brook’s absorbing talk on recent excavations at the Adrian Boult Music centre. Focussed on the Abbey’s kitchen range, Joe further put the findings into context with highlights of our previous excavations in and around the Abbey complex.

The afternoon session, inspired by a forthcoming exhibition on Secret Rivers of London at the Docklands Museum, focused on the Thames and its tributaries. Barry Bishop provided a fascinating tour of the River Wandle in prehistory from its earliest Palaeolithic origins to the Iron Age.

PCA Durham has Moved!

PCA Durham has just completed relocation to newly-refurbished premises in Chester-le-Street; after nearly 17 years in their previous offices this was quite an undertaking.

The new premises have had a long and chequered history and have been used for a variety of purposes over the years, with one part of the building originally constructed as a rope works. The building has been renamed The Ropeworks to reflect this original use. In recent years the building had fallen into some disrepair and the refurbishment has transformed the premises both externally and internally, with the space designed for the wide variety of requirements of an archaeological unit. As soon as everything is in place we will post further pictures of our lovely new office space.

The full address is: PCA Durham, The Rope Works, Broadwood View, Chester-le-Street, Durham DH3 3AF

Well done to all involved and good luck for the next stage!

Triforum Galleries Tour – Westminster Abbey

The Council for British Archaeology – CBA (London) arranged a special visit with an introduction to the archaeology by PCA Director Peter Moore on Saturday 9th February. Peter described the discoveries excavated by PCA: the external corner where the new access tower has been built yielded everything from monastic burials to shop foundations, and centuries of surprises were extracted from thousands of bags of dust retrieved from beneath the triforium floor.

The new Queen’s Diamond Jubilee Galleries in the triforium space of Westminster Abbey are simply stunning. This once hidden section of the Abbey shows off its treasures brilliantly, and all has been enhanced by the archaeological efforts that have helped create the galleries.

This event was popular and fully booked, so if you were one of the lucky ticket holders, we hope you enjoyed this fascinating visit!

An exhibition was held on Saturday 19th January presenting the archaeological findings from PCA’s site at the Boleyn Ground, formerly West Ham Football Club’s ground, in London Borough of Newham. Click the button for a  news article about the site in the Newham Recorder.

The Painted Hall in Greenwich

The painted hall in greenwich 2

Winter bee boles discovered in tudor cellars underneath the Painted Hall in Greenwich.

The painted hall in greenwich

View looking southwest across Painted Hall undercroft and 1510-1550 tiled floor.

Despite several previous archaeological investigations in the vicinity of the Tudor palace, which once stood in the area now covered by the former Royal Naval College and National Maritime Museum, Greenwich, very little physical evidence for it has actually been recovered. Instead a very interesting discovery was made. A Watching Brief by Tanya Jones of Pre-Construct Archaeology Limited was anticipated to continue this trend during an restoration works at the Painted Hall, for the Greenwich Foundation. The site lies within the grounds of the Palace of Placentia, originally constructed in 1443 and subsequently enlarged and altered throughout the Tudor period. It was mostly demolished by Charles II.

The watching brief monitored the lifting of floors and their make-up deposits and initially found 18th and 19th walls and flues, but then a sunken 15m2 room was found towards the north-eastern end of the Painted Hall undercroft. Analysis confirmed that the three extant walls of the sunken room were constructed from small Henrician bricks while the neatly laid floor was constructed of rows of over 100 tiles and 100 paving bricks. The preservation of glazes on the tiles varied considerably but most were plain yellow over a white slip, while a few were glazed black or dark green. Five stone pavers in various sizes were located at the south-western end of the room, possibly close to an entrance and a contemporary stepped feature was also found at the north-western end of the room. The tiles have been dated to the late 15th to early 16th century, but the same paving bricks at Hampton Court are thought to be earlier, dated to the 1520’s to 1540’s. We are currently assuming a construction date of between 1510 and 1550.

The sunken room was visually and historically interesting enough for the Greenwich Foundation, and their architects, Hugh Broughton Architects, to immediately consider how it could be made visible to the visiting public, a challenging feat considering its location was just at the proposed visitor entrance!

However, as the watching brief continued north east of the cellar it revealed first a Tudor wall and then the deeper floors of parts of two vaulted cellars which would originally have had an internal height of about 2m. To date only the interior of one cellar has been revealed, but the external west and south wall of the second has been exposed.  Both of these have niches built into them, four smaller ones in the western wall and three larger ones with chamfered divides and horizontal grooves near the base of the niches in the southern wall, possibly for trays. Although the construction of the cellars is stratigraphically earlier than the glazed and tiled floor they most likely to be contemporary. On seeing photographs of these beautiful niches they were immediately identified by staff member Kari Bower as being “Bee Boles” and within a short time she had found the documentary evidence for Tudor bee boles in cellars used for the storing of skeps (straw/wicker hives) during winter.

Sheltering bees from extremes of weather, including the winter months is probably as old as bee keeping itself and helps the bees to conserve their energy and food stores. Skeps were an early form of hive made of straw or wicker, but the sheltering of skeps in walls (bee boles) is almost unique to Britain and Ireland, while bee boles constructed in brick walls is concentrated in Kent. While the majority of datable examples are from the seventeenth and eighteenth centuries, Kent has several dating to the fifteenth and sixteenth centuries, three of which are in cellars. (See footnote) The earliest printed reference to wintering bees indoors was published by Gerrard Malynes in 1622 and with a bee wintering instruction by Samuel Hartlib in 1655 which might be taken to refer to using a cellar or an outbuilding.

The public access entrance at the Painted Hall in Greenwich is now subject to a redesign to allow both the tiled floor and the cellars with the bee boles to be viewed by the visiting public. Further uncovering of the structures will be required to maximise what can be viewed and interpreted, which will involve further archaeological investigation and recording. As probably a unique opportunity to view Tudor cellars for the winter protection of skeps in bee boles, this promises to be an exciting exhibit.

Exciting excavations in Southwark

Exciting excavations at Swan Street/Harper Road, Southwark.

As you might have noticed, there has been a bit of brouhaha regarding the finding of the Roman period sarcophagus in the course of the recent excavations by PCA on a site at the junction of Swan Street and Harper Road in Southwark. However, unless you looked very hard at some of the photographs you would be hard pushed to know PCA had anything to do with it or that there was anything else found other than the sarcophagus. We are now able to provide a bit more detail on the findings at this fascinating site.

The excavation team from PCA, ably led by Ireneo Grosso, were appointed by CgMs, on behalf of Galliard Homes. The excavations were undertaken in phases over several months and were dovetailed more-or-less seamlessly between the demolition and initial construction works.

The site is located within an area referred to as the ‘Southern Cemetery’, although there is no actual evidence that there is a single unified cemetery but probably a number of discrete burial grounds on the periphery of Roman occupation. To date approximately 500 Roman period burials have been recovered from the Southern Cemetery area, but until recently not one of them was a stone sarcophagus. Interesting burials abound including the famous Harper Road “princess” and high status mausolea along Great Dover Street, That has clearly now changed.
Sadly however, the PCA team were not the first to have discovered the sarcophagus since it was first buried, but it was the first to do it in a controlled and rigorous fashion. It appears that during the process of quarrying chalk from a possible ‘mausoleum’ structure adjacent to the sarcophagus in the  18th century, the massive stone lid prised off and, we assume, the contents at least partially robbed. The lid lay cracked and misaligned, as it was left following this rather less painstaking 18th century investigation!

The sarcophagus itself measures approximately 2.4m long, 75cm wide and 65 cm high and (at least) filled with earth. The significant challenge, given that it was directly on the piling line, was to lift the sarcophagus (which already has several significant cracks) out of the excavation area. This has been managed successfully by a specialist team including Clivedon Conservation, and the sarcophagus has been taken to the London Archaeological Archive and Research Centre, where the fill will be excavated under controlled conditions.

The sarcophagus was by no means the only significant finding of the excavation. A previously unrecorded compacted gravel road, at least 7m wide and flanked on the west side at least by large ditches cut across the site on an approximately NNE-SSW orientation. Roads of this size are considered by the doyen of Roman roads, Ivan Margary, to be in the most important class of roads.  It is conceivable, but not proved, that this was part of the elusive London to Chichester road known as Stane Street.

If it was Stane Street it is on a different alignment and a little to the east of that traditionally held. However, our understanding of the road infrastructure of Roman Southwark is improving, with many more roads identified within the areas of occupation and the Harper Road example may be another one of these.

Towards the western limit of excavation were the chalk foundations of a masonry structure against which the sarcophagus abutted. The structure was parallel to the road, and given this location and relationship, has been interpreted as a mausoleum. These were relatively high status funerary monuments and only previously identified in Southwark at Great Dover Street, which itself is roughly on the alignment of the Roman London to Richborough road.
Moving forward our next steps will be excavating the fills of the coffin. Has it been plundered or and its contents relatively intact? Keep an eye out for further updates on the excavation of the remarkable contents of this extraordinary discovery which has already caused a flurry of excitement in the press..
