Ten days digging at Knepp Castle

From 20 April to 29 April, a community excavation took place at Knepp Castle involving local history and archaeology groups. Richard Nevell looks back on the dig.

I woke up early on Monday 20 April to travel to Knepp Castle, navigating my way before rush hour began. I arrived on site just past 9am and suddenly it was happening. This was the first day of excavations at Knepp Castle, and with a weather forecast suggesting we would get the full use of the planned ten days of digging. More than 50 people volunteered to participate in the dig, joining from Shipley History Society, Horsham District Archaeology Group, and Worthing Archaeological Society as well as volunteers from the Knepp Estate – all under the expert supervision of Chris Butler Archaeological Services (CBAS).

The focus of the ten-day stint was a 5m by 4m trench immediately west of the lone standing wall at the castle. There are a lot of assumptions about Knepp Castle and this was an opportunity to put them to the test, and to investigate an anomaly from the 2022 geophysical survey. The alignment was suggestive, but until we got down to the level of the anomaly what it represented was speculative.

In a broad sweep, Knepp Castle was first explicitly documented in 1210 but is likely older. It hosted several kings of England; featured in King John’s war with the barons; and was dismantled in the post-medieval period. The ruined wall stands tall in the landscape on its mound.

The first step was to remove the top soil. In an incredible feat for English weather, we not only had ten dry and (mostly) sunny days to dig but the weather in the lead-in to the dig has been mostly dry. Most of the time, rain slows things down but a sprinkling on the first day to soften the ground might have helped. That first day was the most physical, with volunteers wielding mattocks to remove the baked dry top layer of the ground. Already, artefacts started emerging – distinctly modern with some glass that might have come from beer bottles and a substantial metal piece of farming equipment which made a very effective paperweight when the weather got blustery.

As we worked our way through the subsoil, along with more animal bones and pottery we started to encounter a lot of oyster shells, mortar, and pieces of sandstone. The interpretation of these finds is pending, but oysters would have been a readily accessible food source.

It is possible that the mortar and sandstone are left over from when the castle was dismantled, possibly in the 18th century. While I’m most interested in the castle’s medieval history, one of my favourite finds was a small fragment of teacup handle. That small piece of ceramic hints at people coming to the castle for a day out, and when the sun shone it was easy to see why. And though I’m no pottery expert, it was instantly recognisable.

Over the course of the next week and a half, volunteers progressed deeper, uncovering more evidence of human activity at Knepp. The medieval pottery coming through and butchered animal bones were evidence of high-status feasting. Nails and stone may have been remnants of buildings at the castle that no longer stand.

An area of burning mixed with slag suggests that some metal objects were created on-site. What we found was the waste from the process rather than the production site itself, but it would likely have been nearby. A volunteer asked me if this had been picked up by the geophysical survey. The magnetometry survey used in 2021 is typically good at picking up metalwork and evidence of burning, but we were digging in an area where there was too much interference from the lightning rod attached to the standing ruin to be able to pick out any detail from that survey.

As digging progressed there were regular questions about what depth we expected to find the anomaly at, and how far there was to go. When we got to the right depth we were faced with a bit of a puzzle. There was a change in soil discernable, and it looked like the anomaly may have been redeposited ‘natural’ – natural is the level at which there is no more human activity.

So what is the anomaly? The hypothesis that it might have been the wall of a building seems much less likely now. That is part of the process of putting theories to the test. At the same time, the process of excavating the castle has provided a lot of information about how it was used. Beyond the medieval period there were some prehistoric finds, pushing the history of human activity on the mound further back than anticipated. There was even a flint arrowhead, which I’ve been told is likely to date from the Early Bronze Age. The mound was a prominent feature in the landscape, and as such seems to have been a natural gathering point for people for millennia.

With the trench backfilled, the finds have been sent to the CBAS office for processing. Specialists are involved in evaluating the materials and refining preliminary interpretations. Once complete, the report will be available on the Castle Studies Trust website. In the meantime, if you’d like to relive the dig as it happened, I recorded some video updates from Knepp.

Looking ahead to excavations at Knepp

Ahead of the fieldwork beginning at Knepp Castle on 20 April, we hear from Dr Richard Nevell, the project lead about the project and what it aims to accomplish.

Ensconced in the countryside of West Sussex, Knepp is perhaps best known as a rewilding project – the first of its kind in England. At the eastern edge of the Knepp estate are the enigmatic remains of a tower. The 11m high wall stands on top of a mound just north of the River Adur, and immediately west of the A24 road. This is what remains above ground of Knepp Castle, and the Castle Studies Trust have awarded a grant to partially excavate the site and better understand what lies beneath the surface.

It is uncertain when Knepp Castle was established. It was likely founded by the powerful Braose family who held the land. The earliest mention of the castle dates to 1210 by which point it was under royal control as King John had confiscated the Braose family’s lands and property. John happily used Knepp as a hunting lodge, visiting to make use of the local deer park. The turmoil of his reign reached Knepp and on two occasions John ordered the destruction of Kneppp to prevent it from falling into enemy hands. Despite this the castle persisted and hosted royal visits from Henry III, Edward II, and Richard II. By the 1720s, most of the medieval castle had been dismantled leaving the lone wall that remains which was likely part of a keep (also known as a great tower).

The keep seen from the east

On 20 April Chris Butler Archaeological Services will begin a community excavation at Knepp Castle, and finish on 29 April. The work involves opening a trench just west of the standing wall, cutting across a feature identified in previous geophysical surveys. The castle is a scheduled monument and legally protected from unauthorised change, so any excavation has to be carefully planned to enhance the understanding of the site while preserving the remains.

View in 3D

The geophysical surveys carried out in 2021 and 2022 showed that there are considerable remains buried at Knepp particularly west and south-west of the standing wall. Part of the challenge with this excavation has been deciding which of these features to investigate. Should we work on what could be a curtain wall marking the edge of the castle, a rectangular shape to the south that could be the trace of a gatehouse, or some of the anomalies on the south slope? In the end we decided to examine a sharp edged feature west of the keep. It looks like it could be a building, but it is on a different alignment to the keep and partly overlaps it. That means it may be an earlier phase of the castle.

The results of the 2021 and 2022 geophysical surveys. Green indicates features identified through a magnetometer survey, and blue those found with ground-penetrating radar. The standing wall is roughly in the middle, and outlined by a red dashed box.

The remains are not immediately obviously castle-like. During the geophysical surveys passing members of the public asked what the site was. The motte is not as pronounced as at other castles, and the wall looks old without necessarily looking like a castle. By excavating at Knepp we hope to better understand how the site developed. The documentary sources give some hints of events, but little information on what was built when. Personally, I hope that we might find some evidence of the destruction of 1216 following King John’s orders, but that’s unlikely.

Though the geophysical evidence is strong, we can’t be certain about the archaeology until we start digging. What has been especially encouraging is how enthusiastic local communities have been to learn about Knepp’s medieval history and get involved with the fieldwork.

Here’s hoping to some exciting finds from Knepp Castle later this month!

Newhouse Dig Diary – Day Five

In his final dig diary Dr Ryan Prescott updates us on the final day of the Newhouse excavation.

Day Five represented the final day of our excavations at Newhouse, and there was much still left to do before we wrapped up our work for the week.

We had found it quite difficult since Monday to find the cut of the ditches from the natural, despite the clarity of their profile from outside of the trenches. While we had the JCB back on site, we thought it would be worthwhile to cut a little deeper into the ditch cuts on both Trench 1 and Trench 2 to determine more about them and their relationship to each other. Certainly, in Trench 1, we seem to have been able to find the extent of the cut and were able to record its measurements and draw sketches which will help us better interpret the nature of the earthworks as a whole. From this, it would appear that the mound was predominantly natural but had been reworked with an accompanying ditch cut around its perimeter.

Again, with the aid of our JCB, we set to work backfilling the two trenches and making sure that the site was returned as much to the state it had been in prior to our arrival. After the welfare unit had been collected, we packed up the car with our equipment, and ensured that the finds would be safely transported back to the office ready for the next phase of our project. We also had a visit from the farmer who was able to point out some other features on the broader site that he had been aware, including a much smaller mound to the north in the adjacent field which had existed until it had been ploughed out some years before.

Now that the fieldwork has been completed, we hope to bring you more information in the coming weeks about what we have found. We are hoping that the picture will become clearer in the post-excavation phase, but Newhouse has undoubtedly proven to be a site even more intriguing than we had first thought it to have been.

Newhouse Dig Diary – Day Four

Dr Ryan Prescott updates us on what happened on day four of their dig

Today we have resumed our efforts in Trench 1.

The two features that garnered our attention in day three required more investigation, so we set to work to try and find the underlying cause of what was going on. We had managed to recover the pot from Trench 1 yesterday, and it remains safely packed for analysis but today we focused on the feature in the centre of the trench where the piece of leather had been found. At first, it seemed that the find had been sitting on a bed of charcoal. However, upon closer inspection (and much more digging!) it revealed to be a deposit of textile material which has remarkably survived and will provide a fantastic source of dating evidence, together with the pot. Small fragments of medieval pottery were also identified in both Trench 1 and Trench 2, as well as further pieces of flint and small animal bone.

Before the end of the day, we also had a visit from the Lincolnshire Historic Environment Record, as well as Peter Connelly from Humber Field Archaeology and showed our visitors what we had found so far. We have all been sharing our interpretations on what we believe may have happened at Newhouse and we have all agreed that the site is far more complex than anticipated. Previous research on the site had only acknowledged its medieval history, chiefly the construction of the abbey on the site of an ‘Anarchy’ period castle. However, it does seem that the mound may have had a much longer pedigree of human occupation which would have been an attractive prospect for Peter of Goxhill who was only too aware of the castles and monasteries which were being founded by nearby lords at Barrow and Barton upon Humber, and was keen to emulate their efforts. We are hoping that the picture will become clearer in the post-excavation phase, but Newhouse certainly has an important story to tell.

We have one more day to wrap up our work at Newhouse for this year, but we have much more work to do before we leave site, so it is shaping up to be a busy day.

Newhouse Dig Diary – Days Two and Three

Dr Ryan Prescott gives an update on what happened on days two and three.

Day Two

Day two of our investigations at Newhouse has seen us focus our efforts on Trench 2.

We spent the morning cleaning the trench and it became apparent that we were looking at two possible post holes nearer the eastern ditch of the earthwork. These were cleaned and carefully dug into before recording was then completed.

On our first day we had unearthed a masonry slab and today we excavated around it to see if there were any other adjoining slabs. Unfortunately, it proved to have been an isolated example. It has been worked with a distinct curve, suggesting it may have been part of a doorway, likely part of the later abbey structures. Though it does not seem to have been in its original context. Nonetheless, it is a nice example which will help us date the activity on the site and build up a chronology. This is especially important as nothing from the abbey remains on the surface of the entirety of the field where we are based. This was one of the key aims of the project.

Day Three

We are grateful to be finally benefiting from some much-needed sun. In good spirits, we returned on our third day to Trench 1 and were keen to see what the day would bring.

Subscribe to our quarterly newsletter

Trench 1 was cleaned up and like in Trench 2, leaving it exposed over the past couple of days had really helped bring some features to light. After clearing a modern rubbish dump of bricks in the southern corner of the trench within the topsoil, we began working on a couple of areas of interest. Day one had revealed some pottery shards, and it became clear that there was more beneath the surface. After trowelling where the shards had been uncovered on Monday, we found the remains of a larger pot. Excitingly, the pot seems to be largely intact but appears to be older than the known history of the site. We also explored a potential feature in the centre of the trench where the soil appeared darker. After much digging, we discovered what appears to have been a small piece of leather, an incredible find. We recorded these two finds and importantly, safely transported them back to the site entrance before they are taken to Humberfield Archaeology for further analysis when the fieldwork has been completed.

Stay tuned to see us progress our work in Trench 1 on day 4 of our excavations at Newhouse.

Newhouse Dig Diary – Day One

Ryan Prescott gives an update on what happened on the first day of digging at Newhouse

The first day of our excavations at Newhouse has provided some promising results already. This week we are excavating two trenches across the earthwork identified last year from geophysical survey (please look at our aims for this year on the CST Blog).

Subscribe to our quarterly newsletter

Trench 1 was swiftly opened with the aid of our JCB. It was hoped that this trench would help corroborate twelfth-century sources that a castle had existed prior to Newsham Abbey, founded here during ‘the Anarchy’. This trench was excavated diagonally from the west to the south-east of the earthwork in order to cut across two of its sides. However, we decided to extend our work in this trench with a perpendicular channel to the southern boundary. At a length of over 40m and 2m wide, the trench has yielded large quantities of flint, some of which appears to have been worked. We have also recovered evidence of burning and pottery finds which we will investigate further as the week progresses.

Figure 1: Trench 1 looking south.

To provide more comprehensive insight into the nature of this three-sided earthwork, Trench 2 was dug across the eastern side of the raised platform and extends from its middle into the ditch on this side at a length of around 25m, slightly longer than initially planned. At first, this trench appeared to show little of interest. Undeterred, we decided to dig deeper into the ditch, and much like in Trench 1, it is clear from this that the earthwork would have been higher than the remains which are left behind. We plan to dig deeper into this later in the week. We cleaned the rest of this trench and discovered a masonry slab, hoping to have a better view of any potential finds and features on our second day when we return to focus on this trench.

Figure 2: Trench 2 looking west with a view of the masonry slab found there.

We are excited to see what the second day of the excavations reveals and will be posting updates as soon as we can.

Newhouse Castle: excavation aims and objectives

Dr Ryan Prescott, project lead looks at what they hope to find at the excavations at Newhouse.

The reign of King Stephen, 1135 – 1154, commonly referred to as ‘the Anarchy,’ was marked by purported political turmoil and discord. Against this backdrop for the struggle for the throne, medieval chroniclers wrote of a surge in castle-building, seemingly in defiance of royal authority. While recent scholarship has since begun to reassess many aspects of Stephen’s reign, the archaeological dimension of these castles remains largely unexplored.

Subscribe to our quarterly newsletter

With the support of the Castle Studies Group Small Projects Fund, a geophysical survey was carried out in the Spring of 2023 to investigate Newhouse Castle, known to have been built in North Lincolnshire amidst the conflict between King Stephen and the Empress Matilda. However, soon after its initial construction, contemporary sources indicate that the site of Peter of Goxhill’s castle was repurposed to establish a monastery, becoming England’s first Premonstratensian House, continuing to prosper until finally suppressed in 1536.

Figure 1: The results of geophysical survey conducted at Newhouse in 2023, funded by the Castle Studies Group.

On face value, the transient nature of the castle at Newhouse is typical of what we have come to recognise for ‘the Anarchy’ period, leaving much unknown about its characteristics, completion, or intended purpose. Through planned excavations made possible by a grant from the Castle Studies Trust, Dr Ryan Prescott and Humberfield Archaeology seek to achieve several key objectives in the summer of 2024:

  • Unearthing the Past: This phase of the project involves excavating the earthwork identified through geophysical survey. By examining the physical remnants of Newhouse, we hope to be able to provide evidence for its construction, size, and layout. This is a crucial step when profiling the site and attempting to determine the reasons why it was first built.
  • Dating Evidence: While historical documents offer some insights into Newhouse’s timeline, the lack of firm dating evidence leaves much to speculation. With two trial trenches planned across the monument, we aim to establish a more accurate chronology of the site, bridging the gap between written records and the physical evidence. This remains a key issue with all sites contemporary to ‘the Anarchy’ and where possible, we hope to be able to address this through the archaeological remains.
  • From Castle to Abbey: One of the most intriguing aspects of Newhouse is its rapid transition from a castle to an abbey. Through an examination of the archaeological evidence and various buried deposits present at the site, we hope to learn more about the structural changes which accompanied this transformation. Understanding how and why Newhouse evolved into Newsham Abbey is essential when interpreting the socio-political landscape of North Lincolnshire.
  • Contextual Analysis: Newhouse does not exist in isolation; it is part of a broader network of castles and religious foundations in North Lincolnshire and the Humber. By comparing Newhouse with nearby sites including the castles at Barrow upon Humber and Barton upon Humber, we aim to gain insights into the regional dynamics of lordly power during ‘the Anarchy’. How did these sites interact, compete, or cooperate in the midst of political instability? These are just some of the questions we hope to answer.
Figure 2: View of the earthwork at Newhouse looking south.

As we now enter the excavation phase at Newhouse, we will continue share our progress through blog posts, video updates, and our excavation findings when the work has been completed. We hope that our research at Newhouse will contribute to a deeper understanding of ‘the Anarchy’, and provide a much-needed local perspective into how lesser magnates, like Peter of Goxhill, expressed their wealth, power, and status through castle-building and religious patronage.

Lowther Medieval Castle Week Four Dig Diary: Into the Labs

In Week Fourth and final week of the Lowther Medieval Castle and Village Project 2024, the team moved into the UCLan labs. This crucial phase allows us to draw together the evidence we’ve collected last year and this, from the recording of trenches to the analysis of soil samples.

Subscribe to our quarterly newsletter

A major part of this process is the transfer of trench plans onto a Geographic Information System (GIS). During excavations, the dig team thoroughly recorded the contents of trenches in situ. This included the painstaking task of drawing the cobbled surfaces found inside the ringwork castle at 1:20 scale. Now, these hand drawings are transferred to the GIS and the outline of every cobblestone is traced digitally so that the archaeological contexts within the trenches be plotted with pinpoint accuracy.

Figure 1 Both last year and this, student archaeologists painstakingly recorded by hand the contents of all trenches
Figure 2 With hand drawings of trenches transferred to the project GIS, each component of the drawing needs to be traced digitally

Meanwhile, the team is also plotting onto the GIS hundreds of data points from around the ringwork castle taken using a Global Positioning System (GPS). This allows us to create a three-dimensional digital model of the ringwork castle, in order to investigate its form and plot the positioning and contents of trenches from this year and last, building up our picture of the castle, its features and finds.

Figure 3 Taking hundreds of data points via the GPS enables the team to construct a 3D digital model of the ringwork castle
Figure 4 Trenches from both phases of excavation can be plotted onto the 3D model of the ringwork castle using the GIS

While one cohort of student archaeologists has been busy in the computer labs, another has been hard at work processing soil samples. Throughout the excavation, the team has been collecting bulk soil samples of 40 litres from all trenches. These samples have now been processed using water flotation, in order to recover charred plant remains, as well as small bones and artefacts. This has so far yielded environmental evidence such as tiny snail shells, which can be analysed to reconstruct the surrounding environment at the time the ringwork castle was built.

Figure 6 Soil sample processing yields environmental evidence, such as tiny snail shells

Now that Phase Two investigations are drawing to a close, the team has also been able to take stock of the small finds garnered this year. As discussed in our last Dig Diary, this year’s finds have included cockle shells and gritty ware pottery, both of which will help us to date the castle and trace activity at Lowther in the Middle Ages. This builds on intriguing earlier finds this year of animal bones, including an articulated fetlock (discussed in our first Dig Diary this year). We can now add to this a bone bead, small but delicately carved, which looks to be dateable to the Middle Ages.

Figure 7 A small carved bone bead found during this year’s excavation

Work on analysing these finds – and the broader phase of analysis – is ongoing, and will be compiled into the project’s second interim report in due course.

Lowther Medieval Castle Dig Diary 2024: Week One

The first week of our 2024 excavations at Lowther (Cumbria) has brought excellent progress. This year we’re focusing our efforts on two trenches. (You can catch up with last year’s excavation on the CST blog).

Trench 7 is sited on the mound at the south-eastern corner of the ringwork. This juts out from the ringwork’s circumferential bank, overlooking the settlement to the east over which the castle presided. Could this mound have held a watchtower or any other structure? Trench 7, across the top of the mound, has so far revealed a stony context, which may be the surface of the ringwork’s built-up bank. A roundish, stone-free context within the trench might be evidence of a feature but might otherwise indicate where a tree has grown in the bank and been removed. There is no clear evidence so far of a structure, but the trench has yielded an intriguing find: horse bones, in the form of an articulated fetlock (ankle) joint. Because the joint is articulated, this means that the horse’s entire fetlock was deposited on the mound (i.e. skin, flesh and bone). Further examination of the bones, potentially including carbon dating, may reveal more.

Figure 2: Jim Morris (UCLan) demonstrates the articulated horse fetlock joint discovered in Trench 7.

Meanwhile, Trench 6 has been opened over the north-eastern quarter of the ringwork castle interior. The trench also stretches eastward through the original entranceway to the castle, which is cut into the eastern bank. The goal here is to reveal much more of the original medieval cobbled floor surface discovered last year, looking for evidence of any structures. If we can find postholes around the entranceway, this might indicate a timber gatehouse (at Castle Tower, Penmaen in Glamorgan, excavations of a similar ringwork revealed evidence of a six-posted timber gatehouse). The castle’s interior may have also have held simple timber buildings, providing shelter for the castle’s guardian and their household.

Tantalizingly, by Day 5 of our dig, Trench 6 was beginning to yield potential evidence of a structure. A dark, rectangular feature is visible within the medieval cobbled surface of the castle interior. We don’t know yet whether it overlays the cobbled surface or is cut into it and, either way, whether it dates to the castle’s earliest phases. It may be that further excavations will reveal postholes, or it may be that that the structure was built simply across wooden beams, effectively floating on the cobbled surface. Hopefully, Week Two will reveal more!

Figure 4: While stuents continue trowelling in Trench 6, Jim Morris indicates the outline of a rectangular feature.

Meanwhile, to the north of the ringwork castle, in a partner investigation supported by the Cumberland and Westmorland Antiquarian and Archaeological Society, we are conducting a geophysical survey. Last year, in Phase One investigations supported by the CST, we surveyed a large area to the east of the ringwork castle, taking in what we think is the original Lowther village, built concurrently with the castle and linked to it by a trackway. Extending our geophysical survey allows us to investigate Lowther as a broader site, extending across the promontory overlooking the River Lowther. What was on this promontory before the ringwork castle was built? How far did the village extend across the promontory? This year, then, we’re surveying at the northern end of the promontory, in the area east of St Michael’s church.

The geophysical survey has run concurrently with excavations across Week One and will hopefully provide evidence of activity at Lowther across the centuries.

Transforming our understanding of Shrewsbury Castle

With the excavation report on the third and final season of excavation which the CST has funded now published on our website, project lead Dr Nigel Baker looks at what has been achieved since the first work in 2019 to now.

Just over a century ago Shrewsbury Castle began a new phase in its long life. In 1925 its principal surviving building, having been in use as a private dwelling since the castle was finally de-munitioned in 1686, became the meeting hall of Shrewsbury Borough Council, set in extensive landscaped gardens covering the remains of the motte and inner bailey, the outer bailey having (mostly) disappeared beneath the growing town by c.1300. Shrewsbury Castle remained more or less untouched by archaeology for the remainder of the 20th century. This changed in 2019 with the award by the Castle Studies Trust of a grant for a season of geophysical survey and excavation in the inner bailey. Following permission from Shropshire Council, the site owners, and Historic England, its legal guardians, the work took place in May and July 2019, the geophysics by contractors Tiger Geo and the excavation team made up of experienced local volunteers and staff and students of University Centre Shrewsbury. The results were unexpected.

Immediately under the turf was natural glacial gravel: the top of the hill on which the castle had been built; the ground surface had been lowered sometime in the past, removing nearly all archaeological remains. This was almost certainly the work of the young Thomas Telford who, from 1786 to 1790, lived in and ‘restored’ the castle for its owner, Sir William Pulteney, M.P. for Shrewsbury. However, archaeological strata were found to have survived within cuts into the natural gravel, and two of these were of major significance. The first was the edge of a previously-unknown ditch around the base of the motte. Medieval cooking-pot sherds of late 11th-13th-century date were found in its lowest excavated layers, along with two armour-piercing crossbow quarrel heads. The second significant find was of a pit containing in its fill a piece of decorated bone and two types of pre-Conquest (Saxon) pottery: Stafford-type ware, distributed widely across the emerging towns of the region and already well represented in Shrewsbury; and a limestone-tempered fabric, TF41a, never before seen in Shrewsbury, which had been made in the Gloucester area and probably imported up the Severn. This confirms that there was pre-Conquest activity on the site of the castle, and, along with the Domesday evidence that there was a church of St Michael there by 1086, may point in the direction of a high-status pre-Norman presence on this tactically-significant site controlling access to the ancient borough.

Shrewsbury Castle Excavation 2020 (copyright Dr Nigel Baker)

Excavation resumed in the autumn of 2020 with a trench seeking a sample profile through the west rampart of the inner bailey. This turned out not to be medieval in date. Both the west and the north rampart were probably created as part of Thomas Telford’s landscaping work in 1786-90. But, intriguingly, below the west rampart there was no sign within the trench of the natural hilltop gravel found close by in 2019 at a depth of just a few centimetres. The explanation may be that the bailey was enlarged westwards between the Norman period and the later medieval period, by dumping soil and levelling-up behind a new curtain wall.

Shrewsbury Castle Excavation 2022 on the motte top (copyright Dr Nigel Baker

The final season of excavations took place in 2022 on the top of the motte, and outside the north curtain wall. Telford is known to have demolished ruined medieval buildings on the top of the motte and replaced them with the surviving two-storey Gothic summerhouse there. Excavation showed that Telford’s activities had, again, removed most of the archaeology but that the foundations of early medieval timber buildings (beam slots, a post pad, post holes) survived where they had been cut into the motte material. No definite trace was seen of the ‘great wooden tower’ which is documented on the motte top until its collapse in 1269-71.

New light was also shed on the motte by vegetation clearance on its south side, revealing for the first time remains of buildings incorporated in the masonry of the retaining walls. This work was undertaken on behalf of Shropshire Council for a new conservation-management plan, currently at consultation stage, which includes photogrammetric surveying of all the castle structures. This permanent stone-by-stone record not only forms the basis for the next vital stage of work – identifying and specifying long-needed repairs – it also offers new archaeological insights, including the identification of the probable primary sandstone rubble fabric of the curtain walls. This was in turn followed by some research carried out by Jason Hurst on Civil War musketry damage in 2023 (Potential shot damage at Shrewsbury Castle – Castle Studies Trust Blog) . And now, the process of publishing this body of new archaeological, architectural and historical information is just beginning…
