Penrith Castle by foot: A new reconstruction

English Heritage is pleased to be a recipient of a generous grant from the Castle Studies Trust to create a new reconstruction image of Penrith Castle (Cumbria, England). Grant co-awardee Will Wyeth (Properties Historian, English Heritage) discusses this work in the context of the charity’s ambitions for public history.

The castle of Penrith, made of striking red stone, is arranged in four roughly equal ranges bounding a central off-square courtyard. Of the two towers there survives, the Red Tower retains its north-east wall and, and the White Tower a vaulted ground-floor chamber.

The column of stone left of it is the remains of the Great Hall external wall with two window reveals. Left of this are the rebuilt remains of what has been called the ‘White Tower’, projecting out from the line of the curtain. On the far left are the remains of the curtain wall standing to wall-head. It is likely a chapel occupied the top floor of this corner of the range. In the foreground on the left are two phases of gatehouse with bridge crossing the ditch. © Will Wyeth

Scholarly consensus ascribes three major phases of construction in the castle: a primary phase of the very late 14th century and two 15th-century phases, the latter of which was the more extensive. It is this last phase, credited to Richard Duke of Gloucester, which is the focus of the reconstruction image.

The castle today is thoroughly urban, and sits within a public park popular with residents and visitors alike. There are several panels offering information about the castle, including an aerial reconstruction of the site in the mid-15th century.

Deconstructing the Reconstruction

The existing reconstruction remains an excellent image. The ranges and towers are carried to full height, the lost courtyard is rebuilt and populated with buildings, while tiny human figures are visible across the site. However, as with many aerial reconstruction images, it has limitations as a device for public history. The image does not aid site orientation for visitors unfamiliar with the ruins or Penrith proper; and life at a human scale is difficult to imagine.

The new reconstruction aimed to address these limitations as well as draw in a further source of guidance. The work of looking after and developing the public history of English Heritage’s properties is supported by a worthy army of volunteers. Penrith Castle is lucky to have one such volunteer, Joanna, who is a true steward of the site’s public history and has led several tours of the castle, gathering  feedback on visitors’ responses to it, and the available interpretation. Through Joanna’s experience, we realised we needed a new image, and imagining, of the castle and its everyday inhabitants.

Rebuilding the Castle

It was necessary to start the process of identifying spaces in the castle from scratch. Several 16th-century surveys mention buildings and spaces with attendant measurements, but the detail is misleading. The missing portions of the site fabric today prohibit confidently identifying spaces such as a hall, chamber, kitchen, accommodations, etc. Certain architectural features survive which can help, but a convincing and comprehensive reconstruction was not achievable.

Figure 3. Buck brothers’ image of Penrith Castle, 1739. The segment of walling on the left with three tall round-headed windows probably depicts a better-surviving portion of the column of stone in Figure 1. In the centre of the image is the tall block (tower?) positioned on the western corner of the castle, now almost completely lost.

Some early images help to locate specific buildings. The Buck image of the castle (1739) illustrates the castle in a more complete state than today – including a complete section of walling where only the reveals and partial window-head of the ‘hall’ survives today – but it also testifies to the presence of a lost tall block positioned on the castle’s west corner (Figure 4).

The great hall was identified by the tall windows in Bucks’ image. This is an unorthodox position. It was unusual for a great hall to be positioned so close to the formal entrance to the castle (in the hall’s primary phase, positioned at the east end of the south range; in Gloucester’s time, just west of the hall). The kitchens which serviced it were also on the other side of the enclosure.

Other ideas were mooted. The presence of a chapel identified with some confidence at the upper level of the east corner of the castle precluded identification with this space in that capacity (see Figure 1). It is possible the three-windowed space was a private or state chamber. While feasible, this pushes the necessity of a great hall elsewhere in the castle where there is not space for it. The high wall outer wall of the surviving south-east range has few outer windows of any significance; the south-west range was, it would seem, dominated by the large tower depicted in the Bucks’ image and resting upon masonry identified with Gloucester’s work; while the north-west range in Gloucester’s time had a number of fireplaces at ground floor whose flues would rise through a first-floor hall set above them, making this alternative, hypothetical arrangement unlikely. For want of alternatives the present consensus, that that hall was in the positioned identified by the Bucks’ three-window wall, is probably correct.

The New Reconstruction

The new image was developed in collaboration with artist Pete Urmston from an existing photograph (Figure 4, left). This captured several parts of the site which we wanted to reconstruct – the great hall with access stairs, Red Tower and parts of the Gloucester-era gatehouse. It incorporates the part of the castle most familiar to passers-by – the Red Tower – and an assemblage of standing features which in general visitors find difficult to understand. This perspective also granted greater flexibility to create scenes of human interaction in the foreground of the image which might populate the castle and convey a sense of Penrith’s medieval community.

Figure 4. Base photograph used for reconstruction (top); first draft of reconstruction (bottom). Note the column of stone on the left image with window reveals is replicated (rebuilt) on the right.

The process of reconstruction begins with a line sketch superimposed upon the base photograph (Figure 4), and hereafter a sequence of amendments and insertions ultimately leads to the final image (Figure 5). The cutaway into the great hall, and beyond into the Red Tower, gives some sense of the grandeur and scale of lost interiors. The clerestory in the hall, inferred from antiquarian sketches and some degree of analogy with that at Middleham Castle, is defined by windows set on a wall carried by a projecting corbel table. A two-door timber screen of late 15th-century design covers off the lower part of the hall. The window-heads of the gatehouse first-floor echo surviving dressed stone fragments found at Penrith.

Perhaps most significantly, the castle is populated with a scene from its tenure by Richard of Gloucester – a meeting of castle staff with tenants and poor folk to hear pleas. A single figure who is attested at the castle and whose presence would be in keeping with a day-to-day scene in castle life in the late 15th-century is represented: Sir Christopher Moresby, depicted on the far left standing with a staff and wearing a green coat (Figure 6).

Moresby supervises under-stewards seated on stools and by a trestle table. Just in front of the restored stair block where a figure descends, painted in Gloucester’s colours of white and blue, are two boys sweeping the yard (Figure 7). Their attention has been captured by a black and white cat standing on top of some barrels. Behind them, through the cutaway, are two figures in the hall basement. One is just entering while the other is sampling (perhaps illicitly) the stores of ale.

In the hall at first floor are three parallel scenes: well-dressed figures are assembled on a long bench and trestle table in the hall proper. A woman enters the screened area at the low end of the hall from the buttery in the first floor of the Red Tower, visible through the inner cutaway. Leaning upon the sole standing piece of wall that survives in this space today, two servants are bringing down a blue hanging.

The new reconstruction aims to place the people of Penrith Castle at the centre of its re-imagination, while bringing back its lost buildings and interiors. In time the image will feature on a new panel scheme in the castle. In the immediate short-term, Joanna the volunteer is already armed with the image and sharing the new light it brings to the castle with visitors.

How Civil Engineering Techniques Can Be Used To Help Inform Cultural Heritage Conservation

Post graduate student Tom Davies explains how he has taken some of the latest civil engineering techniques to help understand the condition of the stone work of old buildings, using Durham Castle as a case study.

Durham Castle was the building of interest for my master’s research project in 2023/4. Durham Castle has an incredible history, being founded in 1072 on the orders of William the Conqueror, to being the seat of the Prince Bishops, to now being part of a UNESCO World Heritage Site and University College for Durham University. The Castle’s rich history and architectural significance makes it preservation crucial, ensuring that its historic features are maintained for future generations.

My research was based on understanding how a section centred around and above the Norman Chapel, the oldest building in County Durham, behaves under ambient excitation. Every structure experiences ambient excitation under normal operating conditions, it is the study of how a structure moves due to natural stimuli such as how it reacts to windy conditions and how it responds to when people move through the structure. Within the section I investigated, the Norman Chapel was on the ground floor, the Senate Rooms on the first floor, and some of the rooms of the Norman Gallery were on the second floor, with the roof above. These spaces, along with their remarkable examples of Norman architecture, make the conservation of this part of the Castle especially vital. The first non-destructive in situ testing I conducted was ambient vibration testing. This involves using multiple accelerometers in orthogonal directions (at right angles, seen in Figure 2) to record how the structure responds to ambient excitation, in this case measurements were undertaken on a windy day. Every building vibrates naturally at its natural frequency, which is determined by the building materials and structural connections of the building among other conditions. The taller the building, the lower the natural frequency, as they are more flexible. The Castle section I looked at is 3 storeys high, so one would expect a higher natural frequency than that of a structure such as the main tower of Durham Cathedral, which is 66m tall. The recorded accelerations were converted into frequency measurements which revealed information about the natural frequencies. This conversion is important, as when plots are made, it is possible to see different modes of vibration.

In order to characterise the masonry parameters that were used in the numerical model and subsequent simulations, another type of non-destructive in situ test was performed, sonic tests. Some tests were undertaken within the Norman Chapel, as this is the oldest part of the Castle, and its masonry has therefore been subject to the most deterioration of any internal section of the Castle due to its age. Additional tests on a masonry panel in a Gallery (corridor) just outside the Norman Chapel were conducted, this is because this Gallery is a very similar age to the masonry of the rooms above the Norman Chapel, from around the 1600s. From this, the different ages, and therefore state of deterioration, of the masonry within the Castle could be included.

Sonic tests involve hitting the masonry, gently, with an instrumented hammer, shown in Figure 3,  and recording the time it took for the subsequent waveform to be registered on an oscilloscope (a machine that shows waves) connected to an accelerometer. Figure 3 shows how this process works, there are two types of waves: P and R waves. The main difference is one travels along the surface of the stone, and the other travels into the stone and reflects off the back of it and returns to the surface. I will focus on the P waves (their names are quite confusing, but it is interesting to know that you can obtain the desired outcome, here the determination of material properties, using either wave). From the recorded wave you can work out the speed of the wave, and using equations you can work out material properties. This is an incredibly important in defining the characteristics of the material within the numerical model. I constructed a finite element model and applied appropriate boundary conditions to represent the foundations of the building, as well as the connections between the section I was investigating and the rest of the Castle. I used the results of the sonic tests mentioned above to determine the masonry material parameters. From the numerical simulations, global frequencies were determined and compared to the results of the ambient vibration testing. global frequency, I mean results that represent the structure as a whole, rather than only a little part of it such as the tower you can see in Figure 4b, or an individual wall. The goal of the finite element model was for its results to be as close to the results of the ambient vibration testing as possible, as this would indicate the model was good at replicating the actual behaviour of the building.

Copyright Tom Davies

Looking forward, there is a plan to undertake a multi-year project to investigate Durham Castle on a much larger scale, building on the work I have done with the target of investigating the entire Castle. The most intriguing prospect is that when a full finite element model of the entirety of the Castle is built, simulations of different loading conditions can be investigated. This would allow different situations to be modelled and the results determined before any physical changes were done to the Castle.

Commemorating Bedford Castle on the 800th anniversary of the great siege of 1224

On Saturday, 24 August, the Higgins Museum in Bedford hosts an event to mark eight centuries since the town’s castle was subject to an 8-week long siege by the army of the teenage King Henry III (booking details at the end). Dr Peter Purton, FSA, outlines what happened in the siege.

Not much remains now of Bedford Castle – just a degraded and much altered mound near the river Great Ouse in the town centre and a few excavated fragments of stone buildings, making it hard to visualise that it was once a large stone-built fortress with a moat, barbican, two wards and a stone tower on top of the motte which marked the original castle built after the Norman Conquest. A display board nearby reconstructs its possible appearance in 1224.

 In that year, Henry III was assembling an army which was to be transported to France in an attempt to recover Poitou, part of the once extensive Angevin empire. This plan unravelled with the rebellion of Fawkes de Breauté. Fawkes had been one of the captains of King John, Henry’s father, and had become rich and powerful. He had been granted Bedford castle and we are told that he had strengthened the fortifications to make it “impregnable”. Rebelling against the crown, he prudently left the country while leaving Bedford in the hands of his brother, who in arresting the justices sent there by the king made it inevitable that he would face royal retribution: this was a direct insult to royal authority and following years of civil war and rebellion following John’s reign, there was no possibility that it could be ignored. The royal army, assembling conveniently nearby at Northampton, was diverted to Bedford. What happened next was recorded in several contemporary chronicles while royal expenditure was detailed in surviving accounts, a combination of evidence which is rare enough and which allows an unusually detailed reconstruction of the siege.

The royal army deployed seven stone-throwing engines (mangonels and petraries) and built two siege towers but the garrison resisted stoutly and inflicted heavy casualties on the attackers. Eventually the barbican and outer ward were breached and captured by royal soldiers then miners, summoned from the Forest of Dean, brought down the wall of the inner bailey and did the same with the tower on the motte, to which the defenders had withdrawn. The prisoners were set free and the entire garrison was hanged as punishment for their rebellion. The castle was then demolished.  A period of instability in England was thereby ended, but so too was English rule in Poitou, the French capturing La Rochelle at the same time as Bedford was being besieged.

These events were therefore of international as well as national significance, and through archaeology, it is possible to now know much more about Bedford castle. All these themes will be discussed at the conference on 24 August, the speakers are Professor David Carpenter, expert and author specialising in this period, Dr James Petre who has written about Bedford, Ben Murtagh who has been exploring Bedford Castle, Jeremy Oetgen (Albion Archaeology) who will update us on a long history of archaeology on the site, and the author of this blog who will place the siege in the context of contemporary siege warfare.

Anyone interested in attending can find all the details and book a ticket at the museum website: www.thehigginsbedford.org.uk. Tickets cost £15 and advance booking is encouraged.

Higham Ferrers – a Royal Town

Project lead, Steve Parry, looks at what he and the team from MoLA and the Higham Ferrers Archaeology and Research Society hope to achieve during their geophysical survey of the once royal castle of Higham Ferrers starting on Monday 15 July 2024.

Walking through the streets of Higham Ferrers you’d be forgiven for thinking that you are looking at a pretty but provincial town.  However, documentary records reveal that Higham Ferrers once played a role on the national stage. During the Middle Ages it had a substantial stone-built castle which served as the headquarters of the extensive Northamptonshire landholdings of the Duchy of Lancaster and from 1399, became a possession of the Crown.  This castle, which was also the manor, would have been the focal point of the medieval town along with other fine nearby buildings including the Church of St Mary, the School House, the Bede House or hospital and the College founded by Henry Chichele, Archbishop of Canterbury before 1425. While these other buildings have survived to the present day the castle fell into disuse and was demolished in the early sixteenth century, with Henry VIII granting building materials from the site for the rebuilding of Kimbolton Castle. John Norden’s map of 1591 shows the site of the castle (‘b’) as broken masonry and uneven ground adjacent to the church, and all that now remains are a ruined dovecote, fishponds, and rabbit warren.

Thanks to a generous grant from the Castle Studies Trust, Museum of London Archaeology (MOLA), will work with Finham Heritage and members of the Higham Ferrers Archaeology and Research Society (HiFARS) to reveal Higham Ferrers’ royal connections through a series of geophysical surveys. We will use a magnetometer to identify any substantial ditches around the castle, as well as the buried remains of internal features such as robbed-out walls, hearths, and pits.  Alongside this, the team will use ground penetrating radar to locate the principal buildings of the castle confirming (or denying!) what our documentary sources tell us – that this substantial medieval building included a hall, chapel, tower house, King’s and Queen’s Chambers, not forgetting three substantial gates. Finally, a resistivity survey will be undertaken, with the particular support of HiFARS members, to provide further detailed information on any buried wall foundations or other structural remains.  The surveys will be undertaken in the various plots shown in this photograph from the 1980s extending from the church (top centre) to the small wood (bottom left-hand corner).

Together with the documentary sources, the geophysical surveys will, we hope, shed light on the evolution of the site by:

  • Seeking evidence of a late Saxon and early medieval manor pre-dating the construction of the castle.
  • Testing the widespread assumption that a motte and bailey castle was built by William Peveril, who held the manor in 1086.
  • Attempting to map the layout of the late medieval stone castle.

The findings of the surveys will be considered alongside those of limited excavations in 1992, to see how the castle and its associated buildings fit within the development of Higham Ferrers from a Saxon administrative centre to medieval market town. The results and conclusions will be shared via a public lecture and published as a report on the Castle Studies Trust website.

The Fourth Crusade: new evidence challenges long-held opinions

The final results are in and Dr Andrew Blackler, project lead for the Dating of the Towers of Chalkida, Greece, reveals the surprising findings of the project we funded in 2022 to try and date the hundreds of towers in the region.

In the autumn of 1204 forces of the Fourth Crusade, fresh from their capture of Constantinople, annexed central Greece. Studies have been undertaken of the major fortifications they constructed, but little is known about the hundreds of towers, which are today a ubiquitous reminder to the modern tourist of the medieval period in the region.

The traditional interpretation is that they were built by the incoming westerners- the minor nobility – as part of a process of colonisation, to display and impose their power over the local Greek population. Yet, since no scientific study has ever been undertaken, we could not even be sure when they were built, and therefore why they were constructed or by whom – until now.

Figure 1: Map of Central Greece with Survey area on the island of Evia (Euboea)
 and the towers sampled (inset)

Following a two-year research program, funded by the Castle Studies Trust and led by Andrew Blackler, a member of the five-year ‘Hinterland of Medieval Chalkida’ survey, surviving towers in central Greece have now been dated using modern laboratory techniques. In October 2022 a team, including technical staff from the Institute of Nanoscience and Nanotechnology ‘Demokritos’ in Athens and from the Ephorate of Antiquities in Chalkida, took samples of wood and mortar from seven surviving towers on the island of Evia (Euboea). This is the second largest in Greece and runs two hundred kilometres down its eastern seaboard. The island, just seventy kilometres north of Athens, is separated from the mainland by a narrow strait only thirty-nine metres wide, the tidal flows of which even Aristotle failed to solve! Chalkida, its capital, became the Venetian administrative centre (as Negroponte) of its Aegean possessions in 1390 and, following its capture by the Ottomans in 1470, their capital of Central Greece for 350 years until the formation of the modern Greek state.

Figure 2. The ruins of a typical tower (Mistros)image description

All of the towers (walls about 8 x 8 metres and height up to 18 metres) were in an advanced stage of collapse. Samples were taken of the wood inserted to provide internal lateral structural integrity to their walls, and of the mortar used to bind their rough stonework. This ensured that these materials were not part of a more recent repair or renovation, which would have been the case for beams used to support the multiple floors of the towers, but part of the original construction phase. The ten timber samples obtained were then subjected to a process of radiocarbon (14C) dating, whilst the mortar was analysed using optical and scanning electron microscopy (SEM) and other techniques (pXRF and XRD) at the Demokritos laboratory.

The results have been exceptional. Six towers from different topographic locations (coastal, floodplain, mountain areas) have been dated with 95% certainty to a period between 1270 and 1434. Unfortunately, the accuracy for most samples was only approximately +/- fifty years due to fluctuations in the cosmic concentration of 14C in the earth’s atmosphere caused by solar activity during the fourteenth century: there were therefore two possible dating ranges identified. Two samples were of sufficient quality that, using what is known as ‘wiggle’ analysis, more accurate dating was obtained.

Figure 3. An example of one sample showing the wiggle in the calibration curve, that causes widening of the calibrated ages and splitting of the ranges.

The analysis of the mortar samples also demonstrated that two towers had two phases of construction. It is difficult to know whether this was a deliberate action or simply a reconstruction due to the collapse of the upper levels, given that the region is subject to frequent seismic activity. More importantly, since we could not identify any timber samples for one tower, it was possible to show that the chemical composition of this tower’s mortar was similar to two other towers in its immediate vicinity and thus was possibly also constructed in the fourteenth century.

The general conclusion, therefore, is that all the towers studied were probably built at least a century, or five generations, after the annexation of the region by western forces, and no towers were built immediately after the Crusaders took control. The ’colonial’ interpretation of their role is thus overturned or, at the least, requires reconsideration. Rather, their construction appears to have been a reaction by landowners to increasing instability in the region following invasion of the island by Byzantine forces in the 1270’s, the threat of attack by the mercenary Catalan Company who took control of Thebes and Athens in 1311, and a growing fear of seaborne assault by Turkish corsairs in the fourteenth century.

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: Week Three

After a bit of a hiatus, co-project lead, Dr Sophie Ambler, gives an update of how the excavations at Lowther Castle went with some possible dating evidence.

Weeks two and three of the Lowther Medieval Castle project brought significant progress, both in excavating a significant portion of the ringwork castle interior and ‘watchtower mound’, and in producing some long-hoped-for finds.

Subscribe to our quarterly newsletter

Trench Seven explored the so-called ‘watchtower mound’, the protrusion of the bank at the ringwork’s south-eastern corner, overlooking the attached settlement to the east, which may have afforded the castle’s occupants an elevated view over the settlement. The trench revealed a compacted stony surface that likely represents a foundation levelling layer. No evidence has been found of a structure having stood on this mound, although it may be that postholes or other evidence of a timber palisade may have been lost over the years to slippage. Soil samples were taken from across the trench and will be tested this week for environmental evidence. Meanwhile, as noted in the last dig diary, the trench had already yielded an equine fetlock joint, which can hopefully be radiocarbon dated.

The final stage of excavation in Trench Seven also revealed further intriguing evidence of activity: two cockleshells, again from a secure context. Cockles are abundant in the bays and estuaries of Cumbria’s coast. Although Lowther is thirty to forty miles from the coast, the presence of cockles is not as unlikely as it may first seem. Excavations at other inland castle sites have shown evidence of bivalve consumption. For instance, a significant assemblage of bivalve shells from across the medieval period has been found at Dudley Castle in Worcestershire, comprising mostly oysters but also cockles, mussels and whelks. Oysters formed the focus of a recent analysis, which revealed that these made up perhaps more than ten per cent of dietary intake at Dudley in the final quarter of the eleventh century (a much higher percentage in the fourteenth century). The challenge of transporting such produce quickly to inland sites made it something of a luxury foodstuff, but one that was clearly popular for castle-holding elites. (Thomas et al, 2018).

Meanwhile, Trench Six, which covers a significant portion of the ringwork castle interior, has yielded several pottery sherds. These were also found in a secure context, here the ringwork’s bank, by the entranceway. The study of medieval pottery in the North West is challenging due to the relative lack of securely datable evidence. This is especially true in Cumbria, which is generally finds-poor for the Middle Ages and where pottery from rural settlements (as opposed to Carlisle) has been less studied. Still, comparators can be found in the pottery assemblage at Cumwhinton, a rural medieval settlement about twenty miles north of Lowther that may have been home to pottery production. Lowther’s sherds appear to be ‘gritty ware’, a utilitarian fabric, most examples of which are from jars and jugs (and occasionally small dishes). This was the dominant fabric used across the north of England in the twelfth century and the earliest form of post-Conquest pottery in Cumbria. (Railton et al, 2014).

Although not definitive dating evidence yet, these finds are contributing significantly to our evidence base, which will help us to date our site and build its biography. We also hope that analysis now being undertaken in UCLan’s archaeology labs will continue to contribute to this evidence base. This includes analysis of soil samples, which may yield environmental evidence, and of finds, including animal bone and the pottery sherds. Watch this space for an ongoing report!

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.

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!

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.

Lowther Castle excavation: season one results and what to look forward to in season two

Phase Two excavations at the putative partial ringwork castle at Lowther (Cumbria) will get underway on Sunday 12th May 2024. The project team leaders Drs Sophie Ambler and Jim Morris look at one they found in season one and look forward to what the want to will be examining in season two.

The Lowther Medieval Castle and Village Project unites History and Archaeology through Lancaster University, the University of Central Lancaster, and Allen Archaeology, with the support of Lowther Castle and Gardens Trust and the Lowther estate team.  Phase One excavations in summer 2023, generously funded by the Castle Studies Trust (CST), saw a geophysical survey of Lowther’s north park and excavations of the ‘castlestead’ earthwork. Phase Two will see further excavations of the castle earthwork, funded by the CST, and a geophysical survey of the area to the north, funded by the Cumberland and Westmorland Antiquarian and Archaeological Society (CWAAS).

The site at Lowther is potentially of great significance for castle studies and the medieval history of Britain. We have good reason to think the site is associated with the second phase of the Norman Conquest: the annexation and plantation settlement of the Kingdom of Cumbria under William Rufus in 1092.

Thanks to the 2023 excavations and their interim report, we can begin to investigate how Lowther sits within ringwork castle typology. This is a partial ringwork, sited on the edge of a promontory, its banks built up on the landward sides. It thus took advantage of its landscape to be seen and to see. This conforms to a model for castle siting that aimed to produce (in the words of Oliver Creighton) ‘a conspicuous symbol of power with a panoptical viewshed over the surrounding territory’. At approximately 27m X 22m, Lowther sits at the smaller end of the ringwork spectrum. In that its central area is raised above external ground level, with landward circumferential banks elevated further, it bears comparison with ringworks of Norman Ireland.

Trench Two investigated the construction of the castle’s north bank. This was one of our biggest undertakings in 2023: the trench measured 15m north-south, and 1m east-west, cutting through the northern bank, all excavated by hand. It was certainly worth the toil. A large block of limestone appears to represent the first layer of the castle’s construction; this is followed by at least four separate building deposits. Seemingly the bank was built up from a number of earthen layers with some smaller stone layers incorporated into the bank, perhaps for stability.

The trench’s southern part, within the castle interior, was also revealing. The stratigraphy, together with the clear level difference between the interior and northern exterior of the castle, suggest how the castle was constructed, first with a great mound, then with bank layers added around the northern, southern, and eastern banks to create the partial ringwork. No evidence has yet been found of a fosse associated with the castle, although Trench Two revealed a small feature at the far north of the trench, of a silty fill cut into the subsoil, running east-west (with a north-south width of 1.52m), possibly a drainage ditch the filled up gradually.

Trench Four began to uncover the castle’s entranceway, in a break in the eastern bank. The removal of topsoil and subsoil revealed a metalled surface, comprising river stones ranging from 0.04 to 0.11m, between 0.20 and 0.15m deep. This seems to be the metalled interior surface of the castle, starting at the entranceway.

Our 2023 excavation yielded little in the way of small finds, although this is not unusual for medieval Cumbria, and may also suggest that the castle was not long occupied. Meanwhile, in the hopes of finding good dating evidence, bulk soil samples of 40 litres (or 100% of a deposit if less was available) were taken from potentially datable features and layers for flotation for charred plant remains and for the recovery of small bones and artefacts. Bulk soil samples were processed using standard water flotation at the University of Central Lancashire. The results will be incorporated in the project’s final report.

Phase Two excavations will go further in investigating the castle’s construction – this time focusing on the interior. Can we identify a gatehouse structure? A potential comparator for Lowther is Castle Tower, Penmaen (Glamorgan), a partial ringwork sited on a promontory, of similar size and likewise with an entranceway gap: excavations here revealed a substantial Norman timber gatehouse, supported by six posts, and fosse. Phase Two will thus excavate an extended area over the entranceway and beyond. And can we identify interior structures (such as the small timber hall evidenced at Penmaen)? Phase Two will open a substantial area – a quadrant of the interior – to reveal the metalled surface, aimed at identifying postholes as well as maximising chances of recovering small finds.

Meanwhile, a partner investigation will get underway in the area around St Michael’s church, just north of the partial ringwork. The castle, village, and Norman church of St Michael’s represent a typical configuration for a medieval manor. The presence of Hogback and other stone sculptures (c.700-1000) at St Michael’s hints at an earlier religious site: can this be established and, if so, what form did it take and how did the Norman settlement overwrite it? And how far did the medieval settlement, attached to the castle, extend northward? Building on our geophysical survey from Phase One, Phase Two’s geophysical survey, supported by CWAAS, takes in the surrounds of St Michael’s.

There is more information on the Lowther Medieval Castle and Village Project on the project website. The 2023 investigation was also featured on BBC2’s Digging for Britain (Series 11 Episode 1), available on BBC iPlayer. The May issue of BBC History Magazine also includes an article on the early medieval Kingdom of Cumbria, placing Lowther’s ringwork castle in its broader context.

Excavations will run on weekdays at Lowther Castle and Gardens from 13th to 31st May 2024. The north park, where our site lies, is free to access. Visitors are welcome! Entrance to the nineteenth-century castle and gardens offers further opportunities to explore the site’s history: the partial ringwork castle features in Lowther Castle’s new exhibition. Information on visits can be found on the Lowther Castle website.
