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?
My name is Annette and I am an Employer Engagement Officer with Wiltshire Council working on a program called Building Bridges.
“Building Bridges is funded by the European Social Fund and the National Lottery, through the Big Lottery Fund.”
Several weeks ago, Wiltshire & Swindon History Centre & Building Bridges set out on a journey of discovery and learning with five would-be archivists with a love of all things past. You could say a real ‘Throwback Thursday’ as this is the day we came together to indulge in something we all love: history.
I can’t believe we have nearly come to the end of our first but I hope not last ‘Archive to Survive’ project.
After attending a learning symposium facilitated by Wiltshire Museum & Heritage Service and hearing a presentation from The Museum of London and the work they were doing with Autism in Museums I was buzzing - I couldn’t wait to do something similar.
Lucky for me I had already formed a working relationship with the fabulous Heather Perry -Conservation & Museum Manager who was nearly as excited as me, and completely on board.
We decided we wanted to target our project at those who may have found it hard to gain paid employment due to anxiety, depression, or other barriers. We wanted to promote confidence and skills learning that would support their journey, and give them a sense of wellbeing and inclusion.
So along with my Building Bridges partners in crime Lorraine, Laura and the lovely Sophie, Conservator (Archives) at the History Centre, we set about putting our plan into action.
If you are reading this it is possible you will know that in Wiltshire & Swindon we have an amazing purpose-built facility that holds the county wide archives. What you may not know is that the public can come in and research things from family histories, to who lived in your house 100 years ago. To do this every document held at the centre needs to be catalogued and this is where we came in.
We wanted to offer an opportunity for a group of people to come in and work with trained professionals to learn all about maintaining and cataloguing this amazing resource. Preserving it for future generations and so Archive to Survive was born.
We recruited five like-minded participants with a love of history and our journey of learning began back in August. Since then we have come together every Thursday and have been building on our confidence and skills, and form new friendships.
This year marks the 70th anniversary of the arrival of the Empire Windrush, which docked in London on 21 June 1948 carrying 492 passengers from the West Indies who planned on settling in the UK. The arrival of the Windrush is traditionally taken to mark the beginning of a period, lasting from 1948 to 1971, of migration from the Commonwealth to the UK – the “Windrush Generation”.
To celebrate the arrival of the Windrush and its passengers, and to mark Black History Month, we have put together the exhibition ‘Wiltshire Remembers the Windrush Generation’ to showcase the stories of some of the many West Indians who came to settle here in Wiltshire.
The exhibition draws on recollections gathered as part of the SEEME project, a Heritage Lottery funded community project where local people and organisations worked with Wiltshire Council, Wiltshire Music Centre & Salisbury Playhouse to collect life story testimonies from Black, Asian & minority ethnic (BAME) elders across Wiltshire to ensure that their stories are recorded and archived for future generations.
Using these recollections it covers the story of the Windrush Generation in Wiltshire, from their reasons for leaving the Caribbean and their first impressions of the UK to their working lives and sense of identity. One of the key themes that runs through all of these areas is the relationship between the new, Black, arrivals and the existing, White, communities in Wiltshire.
For example Rollin, who came to Britain in 1956, remembered clear examples of experiencing racism at work. In particular he recalled “working with a bloke and we’re working, he's my work mate, two of us are working. And he says why don't you go back on your banana tree and all that sort of thing, and I thought why, why you have to say that, y'know? Cause it's stupid! I’d say it's so good I have a banana tree I can go back, but what did he have?”
Likewise Glenda remembered experiencing casual racism throughout her life here, even very recently. “When I first came, I remember someone asking me if we lived in trees, and if we had a tail like a monkey, and but eventually comments like that sort of tailed off. But work wise, I've had problems with work. I mean just before I retired somebody I worked with called me a "black bitch” … I experienced other prejudices, like not being encouraged to further my training … And those sort of things stay with you for such a long time, and you end up getting sort of fearful for how people are going to treat you.”
The racism that many experienced was not confined to words, either – many people we talked to remembered experiencing, witnessing or hearing of physical attacks. Even before coming to Britain in 1961, Sylvia remembered hearing “that they attack black people” in Britain. Whilst living here “I never experienced it, but people would be pushing their babies - black people would be pushing their babies in a pram and some white people would come up and spit on the baby.”
Scotch had a more direct personal experience with racial violence: “in those days there what you call Teddy boys and Angels they used to walk with bicycle chain, knuckle duster and knife and things like that, ready to fight the blacks we have to prepare ourselves to protect ourselves otherwise we wouldn't be here. My brother almost got killed where four white blokes beat him up badly.”
Not all racism was as obvious as this. Tom joined the armed forces and remembers a more subtle (relatively speaking) form of discrimination. “In those days, wherever you got posted, the first thing that would happen was you would go to the camp, hand your papers in and whoever was sitting on the other side of that desk would say ahhh, a West Indian, cricket! And I would say, I do not play cricket. And they couldn’t understand that, you know they’d continue, you guys can really play cricket, what are you, batsmen or a bowler? I do not play cricket. You really don’t play cricket? And that was it. That was me ignored for the next three months. That happened everywhere I went.”
Whilst Tom’s experience of cricket was a tool of exclusion, for others it helped to bring the community together. Bert recalled that “Where I first started off in the type of work I was doing, back in 78/79 actually, there was a police who was killed by a black man in Trowbridge. And it was underlying tension, so I formed the Cavaliers, which was made out of all black people, who played for the Cavaliers. And each year we have two cricket matches against the police, we bring the black community and the police together.”
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.
In 2017 I graduated from the Conservation MA at Camberwell College of Arts and having volunteered for several years in the Archives Conservation department I began work as Assistant Archive Conservator at the WSHC. My role involves being part of the Conservation Museums Advisory Service (CMAS) who support heritage organisations in Wiltshire and beyond. Primarily I work with the archive material held at the WSHC to help maintain and preserve it for current and future generations.
Since beginning at the WSHC in August 2017 it has certainly not been quiet. So far amongst other things: I have begun to master map repair, mounted and tensioned parchment, attended several conservation surgeries, found some exciting things whilst surveying archive boxes, spent seven hours hoovering the strongrooms and made several gluten free cakes for the staffroom! Here are some of the highlights:
One of the parchment maps from our collection was extremely distorted so I used a conservation tensioning method to gradually reduce the cockling. Because parchment is animal skin it behaves very differently to paper and requires specific methods of treatment. It was left tensioning for two weeks before being put in a polyester enclosure and returned to the archive.
Overseers of the Poor Account Book
A project I am currently working on is the Overseers of the Poor Account Book
This is a large project this time involving a very fragile set of pages from 1732. These would once have been bound but now just remnants of thread remain in some pages. The paper is so damaged in areas that it is crumbling away.
One leaf had a pile of severely degraded papers attached with a pin. I carefully removed the loose pieces and pieced them back together where possible.
To make it accessible to the public again each page is being lined with a Japanese tissue. This is translucent enough that the writing on the side of the lining tissue is still visible whilst making the page strong enough to be handled.
Above: applying the lining tissue to a leaf from the volume
The above photograph shows the main leaf and one of the attachments that I was able to piece back together, after both have been lined. The remaining pieces were grouped together by ink and writing type and enclosed in bespoke polyester pockets in the hope that they may be of use to future researchers.
At the end of August I celebrated five years with the archaeology team here at the History Centre in Chippenham. I thought this a suitable milestone in which to reflect on some of the most exciting discoveries in the central part of Wiltshire (the area I cover), discovered through the advice we give on planning applications.
The Government set out its requirements for the planning system in the National Planning Policy Framework in 2012. Section 12 deals with conserving and enhancing the historic environment. The advice we give on planning applications follows this guidance which needs to be relevant, proportionate and necessary. It is important to understand the significance of heritage assets impacted by development, which is why we ask for a proportionate level of investigation to be undertaken prior to determining applications. Various stages of investigation are carried out. To begin with an archaeological Desk Based Assessment (DBA) pulls together existing information, using as a baseline the Historic Environment Record and other sources where available such as historic maps, aerial photographs, field surveys and site assessment. The DBA helps to establish the potential for archaeological remains to be present within a development site. Sometimes, there is little existing information available because there have been few investigations within the area. In such cases geophysical survey is a useful method for revealing unknown archaeological remains within a site. We get greyscale plots and interpretation plans to help understand what potentially is of archaeological origin. In most cases we ask for trial trench evaluation following geophysical survey. Trial trenching enables us to understand the significance of the archaeological remains which will be impacted by development. Depending on the heritage asset’s significance (to use NPPF terminology) we may ask for a site to be preserved in situ i.e. not impacted by development, or preserved by record i.e. it gets excavated, the remains assessed and then reported and/or published. The following examples show previously unknown settlements which have been found through such methods.
Westbury Trial trench evaluation followed a geophysical survey in 2015 which discovered a number of features dating to the Romano-British period including a number of trackways and ditches. The site has yet to be developed.
Melksham Trial trench evaluation followed a geophysical survey in 2014 which confirmed the presence of a Romano-British settlement. The site is currently being excavated, more detail to follow.
At another site in Melksham, a geophysical survey identified a number of features and the trial trench evaluation confirmed remains dating to the prehistoric, Roman, medieval and post-medieval periods. The site has yet to be developed.
Trowbridge Geophysical survey across a large proposed development site highlighted two sites of particular interest. Trial trench evaluation confirmed a concentration of early Romano-British ditched enclosures associated with trackways and pits and posthole features which appear to represent settlement remains. The relationship between the two sites is of interest. More ephemeral prehistoric activity was represented in other parts of the site which the geophysical survey did not pick up.
