East Farm, near the village of Barnham, Suffolk, is an internationally-significant Lower Palaeolithic site dating to 400,000 years ago. Excavations at the site have been ongoing since 2013 and this year we are offering 12 scholarships worth £500 to students who have a desire to pursue serious study of Palaeolithic archaeology to participate in the excavation.
If you would like to apply for a scholarship please complete the application form by Friday 28th February 2020. Candidates will be selected on the basis of a demonstrable interest in Palaeolithic archaeology.
The focus of attention on an archaeological excavations is what’s happening on site but an often-overlooked part of the story is the work done by people away from the trenches which is just as important. Simon Lewis talks to Sophie Hunter about her role in the Barnham Palaeolithic Project.
SL: Sophie, thanks for sparing some time to chat. Please can you tell us about your role in the Barnham excavation? SH: My main job is finds processing; drying and re-bagging fauna; washing and re-bagging burnt flint; washing and marking lithics; packing up finds, ensuring that they are in good order, going to the correct institution and in an undamaged state. I am also the office manager, with a diverse range of tasks including procurement, a first aid and counselling service, and looking after the accounts with the help of Tudor Bryn Jones. After the excavation ends, back in the real world, I also contribute to the post-ex work by sorting residues and preliminary identification of faunal remains.
SL: Which bit of your varied job do you find most interesting and why? SH: This is very difficult to answer as I thoroughly enjoy all my roles. As finds processor, I am incredibly privileged to see and handle every single find that is recovered on site. Doing the accounts is probably at the lower end of the spectrum, for obvious reasons!
SL: Which do you prefer working with, lithics or fauna? SH: Oohh, that’s a tricky one… Both! Lithics are my favourite thing to wash and I like the challenge of writing on the tiny pieces. Choosing a good spot to mark also means that I get a thorough perusal of every flint artefact. Fauna used to put the fear into me, as I assumed it would be impossible to get to grips with – there are so many different species and different bones. If you think about how many different species of mammals, fish, reptiles, amphibians and birds there are (including ones that are now extinct), and tot up how many bones each has, that’s a monumental amount of different bones to learn. However, since taking on the role of sorting the residues from Area III, and with plenty of help from Simon Parfitt, I am gradually expanding the bone bank.
SL: What’s the most unusual find that you have processed in the office? SH: Last year we found a very exciting and special tool. That’s probably the star of the show for this current phase of excavation. A piece of pyrite was also recovered, which will help in determining whether the burning was natural or man-made. This year, the winners are: a large chopping tool and a ginormous core in the flint artefact department; and some amazing lion foot bones (c. 20% larger than the lions we have today), a rhino tooth, and plenty of pond terrapin in the faunal department. A good non-archaeological find last year was a parched and shrivelled up mole carcass, which is in the process of being prepared for the reference collection.
SL: It’s an intensive three week excavation, what happens to all the finds that you process on site when the excavation ends? SH: It is indeed an intensive three weeks, and not solely because of all of the hard work… Different finds go to different places. The lithics and burnt flint go with Nick Ashton to Franks House (British Museum), where they are catalogued by Claire Lucas. The faunal remains go to the Natural History Museum, to be cleaned and identified. The sieving residues also go to the NHM, where they are sorted and provisionally identified. Following this, they are analysed by the relevant specialist (experts in mammals, fish, birds, amphibians and reptiles). Geological samples end up at Queen Mary for analysis. This year we have possible charcoal, so this will be analysed over the next twelve months.
SL: How long have you been involved in the Barnham excavations? SH: Since 1991, when I was 10. The Headings (farmers) introduced me to the team, who kindly took me under their wing. I was hooked immediately – by the excitement of the archaeology, in addition to the very interesting characters and sense of community. It is amazing to be back here again after all this time, and with some of the same people. I have never looked back and feel very lucky indeed to be part of something unique, interesting and fun.
SL: Sophie, thanks for telling us about your varied and interesting work for the Barnham Project.
Simon Lewis talks to Dr Anne-Lyse Ravon to find out more about her first experience of digging at Barnham.
SL: Anne-Lyse, thanks for taking a few minutes to answer some questions. Please can you tell us a little about your research expertise. AR: I am a specialist in Lower and early Middle Palaeolithic lithic industries in Western Europe, but particularly in north-western France, where I direct excavations at the Lower Palaeolithic site of Menez-Dregan.
SL: This is your first time taking part in the Barnham excavations, what were your first impressions of the site? AR: Barnham is a huge site, with different areas to correlate. The geological context is very different from what I am used to in Brittany: I usually work on coastal sites.
SL: What have you been working on for the last two weeks? AR: I have mainly been working in Area I. Our first job there was to expose the surface of the cobble layer excavated in the 1990s, and then to excavate a palaeosol. This palaeosol preserved a lot of charcoal and burnt flint, which is particularly interesting for me.
SL: Has it been successful? AR: Yes, very successful: at the end of the 2 weeks, the excavation of the palaeosol is finished, and we recorded numerous charcoal fragments, which is quite rare for this site.
SL: What have you enjoyed most, and least, about being part of the Barnham team? AR: What I enjoyed the most: identifying charcoal and heated surfaces, because this is something that is very familiar to me, since we have a lot of charcoal and hearths in Menez-Dregan. What I enjoyed the least: the heavy rain during the night which caused a bit of the section to collapse before we arrived on site, and we had to work in the mud that morning.
SL: How does Barnham compare with excavating in France? AR: Same techniques and methods, same recording systems, the only difference would be that in France, we provide all the equipment for the dig, including trowels: here everyone comes with their own trowel!
SL: This is your last day on site, where are you heading for next? AR: Directly to Brittany: I’m heading to Menez-Dregan on Monday, where we are going to excavate for 8 weeks, up to the end of August.
SL: Thanks Anne-Lyse, and good luck with the field work at Menez-Dregan.
There is an important connection between brickmaking and the Palaeolithic in Barnham, as explored by Peter Hoare.
The archaeological site at East Farm is located on the floor of an overgrown pit set amongst arable fields and farm buildings on the edge of Barnham village. Today, we are confronted with a hole in the ground measuring ca 130 m west to east, 70 m north to south and 6 m deep.
Rumour has it that brickearth (a portmanteau term) was quarried here as early as the eighteenth century. A small part of the history of Barnham brickmaking is recorded in the sole surviving ledger, covering the period 22 August 1895–30 December 1912, held by the Euston Estate (East Farm is just one of several properties on the ca 2530 ha estate). So perhaps more than 150 years of brickmaking are unrecorded. Brickearth digging took place seasonally until the 1930s to supply the Barnham brickyard.
No photographs of raw material extraction can be traced, and the only known surviving photograph of the brickyard, which was demolished many years ago, is a small, poor-quality print held by the Euston Estate (reproduced left).
There were two principal types of clay- and silt-rich brickearth: one produced white bricks (Unit 5c of the stratigraphic story), the other red ones (Unit 7). Bricks and related products were made for a great variety of uses on the Euston Estate, but the brickyard also operated on a commercial basis, supplying Lord Iveagh on the neighbouring Elveden Estate, as well as numerous local builders and others.
Apart from the single Euston Estate ledger, no account of brickmaking at Barnham appears to have survived. Peter Minter, owner of the famous Bulmer Brickyard, Essex, has told us that he believes Barnham bricks would have been produced in a similar way to that of other eastern counties brickyards, including his own.
The highly calcareous brickearth from Barnham Area III would have been tempered with sand or less carbonate-rich material; the amount of space available to dry the bricks before firing would have limited the rate of production; and eighteenth-century kilns would have held between 4000 and 5000 bricks. Each man is likely to have made ca 1000 bricks per day in the nineteenth century; it is now ca 500 at Bulmer.
Although the records are incomplete, the peak period of brickearth quarrying and brickmaking probably occurred at the start of the twentieth century. The south and west wings of Euston Hall were destroyed by fire on 5 April 1902, the fourth occasion on which the premises were badly damaged by fire. Rebuilding took place with little delay. Brickyard ledger entries for ‘Mr Heath Euston Hall’ start on 8 June 1903 and end on 15 April 1912, but 89% of the material was produced in the second half of 1903 and in 1905. The wings were rebuilt on the same plan, consuming, amongst other items, 322,975 red bricks, 3500 white bricks, 650 plain tiles, 150 paving bricks and 130 glazed pantiles. The total cost was £577 12s 5p, equivalent to ca £68,000 in 2019. The south wing and most of the west wing were pulled down by the tenth Duke of Grafton in 1952!
Brickearth extraction was responsible for revealing the Palaeolithic archaeology for which East Farm is renowned. The earliest evidence for the discovery of artefacts is of ‘… two flint implements …’ found in 1882, but they probably came from the gravel pit to the east of the village. Other late nineteenth-century finds are likely to have been of an opportunistic nature, some discovered in the wash-pit at the brickyard.
Barnham artefacts purchased from East Farm in ca 1905 included two twisted ovates, one of which is said to have been used by the brickearth diggers to clean their spades! By the time of the first formal excavation at Barnham in the 1930s, the brickearth diggers had produced numerous sections for archaeologists to explore. But that’s another story.
There is just one brief description of brickearth extraction at Barnham East Farm in Ashton, N.M., Lewis, S.G. & Parfitt, S.A. 1998. Excavations at the Lower Palaeolithic site at East Farm, Barnham, Suffolk 1989–94. British Museum Occasional Paper 125, p. 292.

Peter Hoare explains some unusual features of the Breckland landscape that are best seen from the air.
Across substantial regions of the modern world, winters are sufficiently cold to freeze the ground to a depth of several metres, but complete thawing takes place during the following summer. In periglacial regions, with their significantly harsher conditions (mean annual air temperature <−2ºC), long-term freezing may create so-called permafrost that is hundreds of metres deep; ca 60% of Russia, 50% of Canada, 23% of China and 90% of Alaska are underlain by permafrost. Here, summer temperatures are only sufficient to melt the top few metres, forming an active layer. Alternate freezing and thawing of the active layer rearranges the component sediments, and may also disturb the bedrock surface if it is sufficiently shallow. Under these conditions, patterned ground is formed.
Throughout much of the East Anglian region known as Breckland (which includes Barnham East Farm), Upper Cretaceous Chalk bedrock lies within 2.5 m of the ground surface; its upper part is frost shattered (brecciated) and this material is often overlain by windblown (aeolian) coversand and other thin sediments. Large areas of Breckland display inactive or ‘fossil’ patterned ground, consisting of stripes and cellular (often polygonal) forms, indicating that active layer processes took place in the past. Polygons are commonly ca 10 m in diameter; they grade into stripes, which are spaced ca 7.5 m apart, on slope angles of between ca 1° and 6°.
Shallow-lying patterned ground is evident at the surface because vegetation responds to variations in subsoil characteristics (particle size, pH, depth, moisture content, etc.) created by periglacial processes. Crop- or scorch-marks such as those seen in the photograph were especially clear during the long spell of hot and dry weather in the summer of 2018. Every other Breckland stripe is underlain by coversand with a pH of <4.5 (acidic) and heather thrives; Chalk bedrock lies close to the surface beneath the intervening stripes, the soil pH is >8 (alkaline) and grass flourishes.
In the most recent study of the Breckland patterns (Boreham & Rolfe 2016–17), the authors concluded that Devensian (MIS 2) frost cracks developed into what they termed ‘tiger’ stripes; solifluction played its part in drawing material downslope. Although the exact mechanisms underlying patterned-ground formation in Breckland are not fully understood, their presence may be used to say something about former climatic conditions.

Nick Ashton, Simon Parfitt and Simon Lewis discuss the research highlights of the archaeological excavations at Barnham.
Archaeological excavations in an abandoned brickearth pit at East Farm, Barnham have uncovered one of the richest Lower Palaeolithic archaeological sites in western Europe, dating to about 400,000 years ago. Finds include butchered large-mammal bones, flint tools and evidence for fire.
The 1989-94 excavations established the significance of the site, with its in situ artefact assemblages and its substantial quantities of vertebrate remains, include fishes, amphibians and small and large mammals. The second round of excavations that started in 2013 have refined our understanding of these lithic assemblages and also provided an opportunity to explore the evidence for technological transitions and how early humans developed strategies for survival. Recent investigations at the site have identified an earlier core and flake industry that was replaced by a later handaxe industry (Clactonian and Acheulian respectively). This technological transition may reflect arrival of different human populations into Britain from different regions within Europe, bringing with them different technologies.
Area III, pictured in a photogrammetric reconstruction of the excavation (above), shows ‘islands’ of undisturbed sediments cut by late 19th and early 20th century brickearth pits. These sediments contain stone tools and a rich assemblage of vertebrate remains. Area III has provided important evidence for the environment in which early humans lived; pollen grains contained within the sediments enable the vegetation at the time to be reconstructed and the landscape can be populated with both large and small animals based on the fossil remains found in the sediments.
Among the many examples from these deposits are a macaque tooth and elements of pond terrapin carapace (shell) indicating warm conditions and diverse habitats that included both woodland and aquatic environments.
In a different part of the site, the excavations in Area VI, revealed a new dimension to the Barnham story; along with the many flint artefacts that make up the lithic assemblage, there is also a surprising quantity of burnt flint. This material, with its distinctive cracked and crazed surface and often red colouration, was found within the black clay, a layer that we know to have once been a land surface as it shows signs of soil development.
As the excavations have progressed, our research has focused on this evidence for burning and the critical question of whether the burnt flint, which includes some artefactual as well as natural pieces, provides evidence for hearths or does it record ancient forest fires?
To address this question we have excavated and carefully recorded the spatial distribution of hundreds of fragments of burnt flint in order to plot the variation in density across the excavated area. We are also using laboratory analyses, particularly Fourier-transform Infrared Spectroscopy (FTIR) to identify heating signals in the sediments. Another avenue of enquiry is the use of experimental fires, set and maintained under carefully controlled conditions, to investigate the changes that take place within and beneath a hearth.
If the evidence points to human use of fire, this would provide further indications of the development of new technology that goes beyond the stone tool evidence and it may also begin to tell us something about societies and culture in the different human groups that entered Britain during this interglacial some 400,000 years ago.
With a focus on the archaeological and environmental evidence, the Barnham Palaeolithic Project is able to address important questions concerning Palaeolithic societies 400,000 years ago at spatial scales ranging from domestic sites with evidence of fire through group territories to relationships between groups across Europe.
On the eve of the 2019 season, Simon Lewis reflects on three decades of fieldwork in the Breckland.
In 1989 a team of six people, led by Nick Ashton, ventured into the old pit at East Farm, Barnham. Armed with spades, mattocks and trowels, and guided by information from earlier investigations by TT Paterson and John Wymer, the aim was to explore the potential for fresh excavations at this important, but perhaps somewhat overlooked Palaeolithic site. In the 1980s the British Lower Palaeolithic was dominated by Boxgrove; excavations were in full swing and the wealth of new data emanating from the excavation’s HQ in farm buildings near the site was transforming our understanding of early human behaviour and the environments in which they lived as well as setting new standards in excavation, recording and sampling procedures. In contrast to the scale and organisation at Boxgrove, excavations at Barnham adopted, from the outset, an approach that suited a small Breckland brickearth pit abandoned since the early years of the 20th century, now completely taken over by oak trees, hawthorn and bramble thickets and with little to disturb the tranquillity of the location.
John Wymer’s work in 1979, had revealed the potential of the site; he excavated a small area and recovered a refitting group of 13 flakes and a core. The team set about the task of re-exposing the sediments and the archaeological levels, previously described by Wymer. The 1989 results demonstrated that there was indeed scope for larger-scale excavations at the site and so, with the enthusiastic support of the Heading family at East Farm and the Euston Estate, began a six-year programme of fieldwork at East Farm. The results of these investigations have been published in a comprehensive volume, as well as papers in academic journals.
After the 1989-94 excavations ended the now-established research team turned their attention to another Breckland site; the former pit at Elveden, some 7 km west of East Farm. Excavations at Elveden ran from 1995-99 and together these two sites provided important new geological, environmental and archaeological evidence for understanding the Palaeolithic of the region.
Nineteen years after concluding the first round of excavations at East Farm, a decision was taken to return to the site. There were three main reasons for doing this, the first was to re-evaluate the key archaeological question of the relationship between Acheulian and Clactonian assemblages in the light of wider developments in understanding of this problem in the intervening years. The second was the opportunity to add to the already rich environmental information from East Farm, in particular to increase the vertebrate assemblage and to explore the linkages between the archaeological and environmental evidence. The third was to provide an opportunity for archaeology students to gain experience of excavation on a Lower Palaeolithic site. Following on from the work at Happisburgh with the Faculty of Archaeology at Leiden University, Barnham provided an ideal setting for this.
So 2013 saw a return to East Farm, with a small team of Dutch students, to embark on a new programme of research again led by Nick Ashton. The first season was primarily about finding our feet again and identifying areas for excavation. Over the subsequent five seasons, archaeological work has focused on the southeast corner of the pit, Area IV(4), where evidence of handaxe manufacturing had been found in 1994, which has now been expanded into the adjacent Area VI. The environmental work focused on the centre of the pit, Area III, which has been considerably enlarged from the earlier work. Material excavated from Area III has been processed on-site; several tonnes of sediment being excavated, dried, disaggregated and sieved during the course of each season.
This second Barnham campaign has already provided an array of new information. Among the key developments since 2013 are the reassessment of the stratigraphic relationship of the handaxe and non-handaxe assemblages, the addition of several new species to the faunal list, the discovery of an intriguing burning signal though recovery of large quantities of burnt flint and location of an organic deposit, with a pollen profile showing the development of interglacial woodland vegetation. We have also welcomed students from several UK universities alongside new and returning Leiden students.
As the 2019 season gets underway, with new and exciting objectives for this year’s excavation, it is good to look back over thirty years of excavation and related research in and around the Breckland area. As always, the support of the British Museum, as well as other funding bodies through the Ancient Human Occupation of Britain (AHOB) and Pathways to Ancient Britain (PAB) projects and the Breckland Palaeolithic Project, has played a vital role in the excavations at Barnham and other Palaeolithic sites. Three decades of collaborative research in the Breckland, with fieldwork at East Farm playing a prominent part, demonstrate that a great site and a dedicated team of people, united by a shared interest in the lost world of our distant ancestors, are the foundations on which this endeavour has been built.
