Exciting and unexpected archaeological discoveries show how no evaluation process for sites is fool proof. What happens next shows how important cooperation and communication is, particularly for the County Archaeology Service, who are tasked with supporting development AND safeguarding heritage. The critical concept is “significance” – how important are the remains; what is their potential to inform us about the past? Rachel Foster, Assistant County Archaeologist reports:
In 2017 Wessex Archaeology excavated a new housing development north of Bitham Park in Westbury. I had requested this work as a condition of planning permission, based on limited evaluation results. Unexpected discoveries demonstrated the challenges faced by Planning Archaeologists in understanding the significance of archaeological sites based on the results of trial trench evaluation.
The 2018 National Planning Policy Framework states that local planning authorities should identify and assess the particular significance of any “heritage asset” that may be affected by a proposal. In line with this advice, we often ask for sites to be investigated before the determination of a planning application, so that we have that information. Evaluation usually this consists of geophysical survey followed by trial trench evaluation. The Wiltshire and Swindon Historic Environment Record which contains detail on archaeological sites, buildings and finds, informs our decision making.
Archaeological evaluation can feel like a game of battleships. When geophysical survey goes well, and reveals features that look like potential archaeology, we ask for trenches to be dug and the features investigated by commercial archaeologists. The aim is to understand the significance of the site by investigating features within the trenches, which is not always so easy: if geophysical survey has not been carried out or is unsuccessful, then trenches are placed either systematically or randomly across a site and there is potential to miss remains. Today, the trenching is usually a 3-5% sample of the development site but in exceptional circumstances, up to 10% may be carried out. That sample of trenching should find archaeological remains within a site and provide enough information to understand the importance, extent and significance of any remains. Results of evaluation will then inform our advice to the planning officer on the impact of the development on archaeological remains. Remains considered to be of national significance are likely to be preserved in situ and not developed, but other remains are likely to be investigate. Early knowledge about archaeology and its potential effect helps the developers manage their risk and adequately budget for excavation costs, as well as post-excavation work and publication.
The geophysical survey results at Bitham Park didn’t show much other than a few lines representing ridge and furrow remains across parts of the site and a few other possible linear features. This image gives an example of the greyscale plot of the geophysical survey results (magnetromotry).
Geophysical survey isn’t always reliable, so I asked for trial trench evaluation prior to determination of the planning application: in some cases, later ridge and furrow can hide earlier remains. As the geophysical survey indicated, there were remains of medieval/post-medieval ridge and furrow cultivation; however, my assessment that there might be more archaeology was correct. Archaeological features were discovered across several trenches, mostly concentrated in the western part of the site. They included ditches, gullies and pits containing small, worn pottery fragments from the early/middle Iron Age and Romano-British periods (150BC onwards). Nevertheless, the significance and extent of the remains could not be fully understood, so I asked for a second stage of evaluation to provide more data. The extra information would help me define an area for archaeological mitigation – the full excavation of important features. The results confirmed prolonged and intensive agricultural use from the medieval period (1066- 1540). This had truncated and displaced features and artefacts from the earlier Iron Age and Romano-British periods; however, theses features included and arrangement of post holes representing a possible structure (see trench locations of two evaluation stages below).
On the basis of the two evaluations I asked for an area of excavation within the vicinty of where the most significant archaeological features were recorded, in the western part of the site and along a north-south trajectory.
In advance of the housing development an initial area was stripped with contingency and here’s an aerial view of the site below, can you spot anything interesting?
(*or what was held to be The Truth in the Middle Ages)
At the summer solstice, Stonehenge falls under the spotlight: in the solar sense and in the cultural sense. People all over the world find it fascinating and are reminded to ponder it when the sun is at its highest. Much of the appeal of Stonehenge may be attributed to its encompassing aura of mystery, its air of mind-bending antiquity. There is much about it we don’t understand, despite the advances made by ingenious researchers, but we are not the first generations to try to account for Stonehenge. So what did our forebears believe?
According to a twelfth-century author called Geoffrey of Monmouth, the ancient stone circle now known as Stonehenge was originally brought to mount Killarus in Ireland from Africa by a group of giants. It was known then as the Giants’ Dance and had healing properties. The stones came to Wiltshire with the help of a very young Merlin, at the behest of King Arthur’s uncle, Aurelius Ambrosius, to be reconstructed as a memorial to a group of Britons massacred during the reign of the malicious usurper, Vortigern. Some decades later the structure renamed Stonehenge becomes the final resting place of Uther Pendragon.
I studied this story while writing my PhD about an illustrated medieval manuscript containing an abridged version of Wace’s Anglo-Norman French translation of Geoffrey’s history: La Roman de Brut. Even in its shortened form, the episode in which the child Merlin guides the reconstruction of Stonehenge celebrates brains over brawn, great power despite littleness of stature:
“They grasped the stones behind, in front and sideways: they pushed and thrust them hard and shook them hard, but however much force they used, they could not find a solution. ‘Rise’ said Merlin, ‘you will so no more by force. Now you shall see how knowledge and skill are better than bodily strength.’ Then he stepped forward and stopped. He looked around, his lips moving like a man saying his prayers. I do not know if he said a prayer or not. Then he called the Britons back. ‘Come here,’ he said, ‘come! Now you can handle the stones and carry them into your ships.’ As Merlin instructed, as he devised and told them, the Britons took the stones, carried them to the ships and placed them inside. They brought them to England and carried them to Amesbury, into the fields nearby.” – Based on Judith Weiss’ 2002 translation of Wace’s Roman de Brut
To the medieval mind, the stone circle was a monument to human mastery of nature, as well as to the fallen Britons. Still today we measure ourselves by the power of our prehistoric ancestors to have created it. I recently created a linocut of the child Merlin guiding the reconstruction of Stonehenge. Both Geoffrey of Monmouth and Wace focus on the dismantling of the stones in Ireland, which is also the moment illustrated in the manuscript I worked on for my PhD. Instead, I depicted the moment when that iconic plain was undergoing its momentous transformation.
Do you have an interest in archaeology? Would you like to know what has been found in your local area, or want to know more about how people lived in Wiltshire in the past? If so, then you might be interested to access our new website that allows you to research the finds, buildings, sites and monuments that exist on the county Historic Environment Record (HER).
The Historic Environment Record (HER) is a fantastic resource that holds information on all the currently known archaeology for Wiltshire and Swindon. This includes everything from Palaeolithic flint tools that are half a million years old to World War I practice trenches created only a hundred years ago – as well as everything in between! Using the HER can be fun and helps to guide your research, as it can tell you about the character and date of archaeological sites/finds as well as how they have been investigated and where you can find more (such as in journals, books and reports).
The new website allows people to easily search the archaeology of Wiltshire and presents data on both a map and dynamic database. To have a go, click to visit the HER homepage
The new website is easier to use than our previous one and allows you to search by the following themes: • Unique identifier number – so you can find records you’ve accessed before… • Keyword – to find particular find/site types – such as castles or axeheads! • Site name – for place names you know like your parish church or famous sites like Stonehenge! • Period – so you can see all Roman artefacts or all prehistoric archaeology we know about… • Grid reference – if you know exactly where you want to research - whether rural or urban!
You can also browse by navigating the interactive map – which can show both Ordnance Survey mapping or aerial photography. You can pan and zoom using the tools and the grid reference of your location handily shows at the top in case you need it!
A number of Roman finds were recently uncovered in the back garden of Marc Allum, a specialist on the Antiques Roadshow, during excavations organised by Chippenham Museum volunteers Clive Green and Mike Stone.
Mr Allum kindly donated the finds to Chippenham Museum. The Friends of Chippenham Museum worked hard to raise funds for the conservation of one of the finds - a fine Samian ware bowl - and conservators at CMAS were privileged to undertake the reconstruction of this beautiful piece.
The Samian ware is an example of a Dragendorff type 37 bowl, suggesting it is Gaulish dating from c. AD 70-130. The bowl has intricate decorative panels with repeating motifs of Gladiators battling wild cats and a more risqué scene thought to depict the deity Bacchus.
The Samian ware was found in 51 fragments forming almost half the bowl. Due to the fine nature of the form and decoration it was decided to fully reconstruct the piece, replacing lost areas to give more complete impression of its original form.
The conservator worked hard to piece together all the fragments. Interestingly the way the ceramic had broken into layers reveals its method of construction. Samian ware with such detailed patterns was formed by pressing clay into preformed moulds. The ceramic has split along the lines of the layers that were built up.
Graham Taylor of Potted History (@Pottedhistory) has created replica moulds for the vessel and its decorative features in order to produce a facsimile using the same techniques.
Once the form of the original ceramic was determined it was possible to create an accurate profile from base to rim using measurements of the thickness of the ceramic fragments and the diameter of the base and rim, comparing these with known examples.
The profile was used to form an accurate core in clay to which the original ceramic could be secured. Plaster replacement fills were then ‘spun’ using the profile as a guide. It was decided to only replace larger areas and those smaller areas required for strength.
We could see the enemy’s whole body of horse face about and run with speed… and our horse in close body firing in their rear, till they had chased them down the hill in a steep place, where never horse went down and up again.
Sir Henry Slingsby, Royalist Cavalry Commander, describing the endgame of the battle of Roundway Down.
Slingsby’s laconic words describe the best-known moment of the 1643 Battle of Roundway Down, when the broken Parliamentarian cavalry were chased from the field by the troopers of King Charles I. During this rout, both those fleeing and their pursuing enemies rode off the steep, western edge of the chalk down. The moment captured the imagination and that part of the down is known as the Bloody Ditch!
The rout of the Roundheads might be the most famous part of the action, but it was part of a bigger battle that was, in turn, part of a wider campaign as both sides tried to take control of the west of England. Both sides were seeking to exploit the region’s resources, recruit its menfolk, seize the horses and tax the populace, who were, often unwilling, participants in the increasingly bitter civil war that had broken out in 1643. Meanwhile, the battle took place on chalk downland that had already seen millennia of human activity, the landscape is rich in archaeological remains as a result, with barrows and a hillfort. The edge of the downs also gives superb views across the surrounding landscape and its archaeology.
In early September, we led an archaeological walk across part of the battlefield to explore and explain both the flow of the battle and the more ancient remains in the area.
The Roundway Landscape
The Wiltshire Historic Environment Record includes data for a number of later Neolithic or Bronze Age barrows. Like many other barrows in Wiltshire these occupy prominent locations with extensive views into the wider landscape. They have also, like many similar monuments, been investigated by 19th century antiquarians. Although some of these monuments are similar to others in the county, with prehistoric burials beneath and within earthen mounds, one barrow is exceptional. When it was opened in the 19th century a number of metal fixings were found that suggested there may have been a bed burial inserted into the Bronze Age mound during the Anglo-Saxon period. Bed burials are an unusual Saxon burial practice, usually reserved for women of high status, another example in Wiltshire comes from Swallowcliffe, between Salisbury and Shaftesbury, with others known elsewhere in Wessex and around Cambridge. These bed burials appear to date to the 7th Century AD and may relate to the conversion of England to Christianity, and the woman was buried with a dress pin decorated with a cross. The burials may also relate to the wider power struggles between the Anglo-Saxon kingdoms, including the expansion of Wessex. The mound and the artefacts were re-investigated by Sarah Semple and Howard Williams in 2001 when they suggested that the Roundway burial might actually have included an elaborate coffin, rather than a bed. Whatever the mode of burial, the status of the deceased remains in no doubt, while the reuse of the much older burial mound is typical of Anglo-Saxon burials associated with barrows. This practice suggests not only the use of the barrows as landmarks, but also that they retained some form of mythic or folkloric power to the people of Anglo-Saxon England.
The walk also visited Oliver’s Castle, an Iron Age hillfort that overlooks St Edith’s Marsh. This monument includes a ditch and bank creating a rampart that encloses a promontory on the edge of the downs. The ramparts respect two earlier Bronze Age burial mounds. When excavations took place in the later 19th century, there was little trace of settlement, suggesting that the hillfort was, perhaps, used as a place of safety in time of danger, or that it was used for ceremonial events. In either case, the prominent location meant that views of the surrounding landscape were excellent, whether to see enemies or to be closer to the gods. The site enjoyed a later life as a sheep fold; a dew pond, providing water for sheep and probably originating in the 18th century, still survives within the ramparts. By the later 19th century, a shepherd is known to have had his hut close to the pond.
Below the fort is a site known as Mother Antony’s Well. This has been the site of excavations in recent years that have found probable Bronze Age barrows, an Iron Age enclosure, and Roman remains that included kilns used to dry grain. In addition, the Romano-British population seem to have regarded the springs in the area as special, and one had an elaborate well head that may suggest a shrine.
With all this lovely sunshine in the last few weeks, it has been good to see so many people of all ages getting out and about in the great outdoors. I have been doing quite a lot more walking myself recently and it has reminded me how lucky we are in Wiltshire having so many monuments and historic places that are easily accessible and make great walks. Many of our sites and monuments are very impressive, give commanding views and are free to enter.
I have always enjoyed that physical engagement with the past that you get from climbing up to a steep ancient monument, such as an Iron Age hillfort, a castle mound or the top of the spire of Salisbury Cathedral. The physical exertion has always helped me to understand the scale of effort required by the people who built them and encourages enquiry about who, when and how the monuments were built.
I distinctly remember my first visit to Maiden Castle Hillfort in Dorset when I was 9 or 10, and after a steep walk the sense of discovery and wonder at the size of the ditches and banks. Several decades later, three of which as an archaeologist, I still get that same buzz about visiting these types of site, and what better way is there to get fitter and heather and explore our wonderful monuments at the same time?
Since 2007 the Wiltshire Council Archaeology Team has been organising annual archaeology walks each summer, usually to coincide with the annual Festival of Archaeology organised and promoted by the Council for British Archaeology in July and August. The walks, led by members of the Archaeology team have been very popular and have include places such as Avebury, the Stonehenge landscape, Littlecote Roman Villa, Barbury Castle, the Wansdyke, Adams Grave and Knap Hill and Oldbury Castle.
The very first walk I led as County Archaeologist in 2007 was one of the most challenging. It was a very rainy and wet Spring and Summer and the July walk to Avebury, Silbury and West Kennett Long Barrow was hampered by flooding, so much so that we lost some of the group as they weren’t wearing appropriate footwear to wade across the flooded Kennett on the way to the Long Barrow. Nevertheless, there was plenty to talk about at Silbury as English Heritage were in the process of repairing the Hill after a partial tunnel collapse some months earlier. The repair work was a great opportunity archaeologists to learn more about the monument and how it was built. The 2014 publication of the results by Historic England are fascinating.
This year for the first time in 27 years the Council for British Archaeology is taking a break from organising the Archaeology Festival. However, the County Archaeology team are still organising three exciting and diverse walks, one each in July, August and September.
Sunday 29th July - Iron Age Hillforts. Starting at Battlesbury, Warminster
Long before the Army started training on Salisbury Plain, and even before the Romans ruled, massive earthwork defences were created on the chalk downland. The edge of the Plain above Warminster has been sculpted to created massive hillforts over 2000 years old. Were these structures intended to defend ancestral lands, or to say "this is us”? Were they citadels, granaries, or temples? The hillforts enclose older remains – sites of burials and sacred places, so there may be more to them than defence and power. Join us as we explore these massive monuments and the landscape that they occupy, see how archaeology has deepened our understanding of the hillforts and wonder why, after so much work, one fort may have been abandoned before it was finished.
Sunday 5th August - Avebury World Heritage Site
Avebury is well known for having the largest Prehistoric stone circle in the world. However, the stone circle is surrounded by a range of other funerary and ritual monuments dating to the Neolithic and Bronze Age, some of which are unusual and unique. This exciting tour takes you through and between the monuments, exploring the monuments and their relationship with the landscape. The tour will take in the Avenue, Waden Hill and Silbury Hill amongst others and explore the reasons why the Avebury landscape has been designated as a World Heritage Site.
Sunday 2nd September - Oliver’s Castle Roundway Down Battlefield, Bromham
The Battle of Roundway Down was fought on 13th July 1643, when the armies of King Charles I and Parliament clashed on the hills above Devizes. Our walk will explore the battlefield and its importance, as well as its place in the wider landscape. Join us to find out why there were Lobsters on the battlefield, how the Bloody Ditch got its name and what occasioned Charles I’s only recorded joke. We might also explain where Devizes castle went.
We will also explore the remains of much older monuments, Oliver’s Castle Iron Age hillfort and associated burial mounds, which are testament to how our Prehistoric ancestors used this landscape for settlement, defence and ritual activities.
The walks promise to be interesting and stimulating events for all age groups. They all start at 11 AM on a Sunday morning and will involve walking for 2-3 hours. The Iron Age Hillforts walk may be a little longer (3-4 hours).
All our walks are free but you will have to book a spot as we have a limit on numbers.
