Project leads, Drs Sarah Jane Gibbon and Dan Lee reveal the results of the geophysical survey part of their project on The Wirk funded by the Castle Studies Trust.
Thanks to a grant from the Castle Studies Trust, ateam from the Orkney Research Centre for Archaeology undertook geophysical survey at The Wirk, Westside, on the island of Rousay, Orkney in September, despite the challenges. Long grass was cleared from the site and a grid was established to the north, east and west of the stone-built tower. Two techniques were used: magnetometer survey (good for identifying magnetically enhanced material from burning and settlement activity) and earth resistance (good for locating walls and structures).
The aim is to better understand the nature and date of the tower which has variously been interpreted as a 12th century Norse Castle, a hall-house tower, a defensive church tower and a 16th century tower and range. Previous excavations by J. Storer Clouston in the 1920s cleared the stone tower and exposed a large range to the east, although phasing of the buildings remains unclear. The tower was left exposed but the area to the east was backfilled. A scale plan was made but recording and description of the built remains was minimal.
High-resolution magnetometer survey and targeted high-resolution earth resistance survey was undertaken across the site in order to characterise the buried structures, put the tower and hall in context and inform trench location. Clear anomalies were identified in both surveys at the site of the hall, with potential wall lines (high resistance) matching the main part of the building in Clouston’s plan to the east of the tower. This suggests that wall footings are likely to survive just below the ground surface. Other high resistance anomalies to the south of the hall could indicate the presence of additional structures. Results from the magnetometer survey showed strong positive and negative anomalies within the footprint of the hall and confirmed the presence of a possible enclosure to the south. A curvilinear positive anomaly to the north-west of the tower, beyond the apron, could indicate the presence of another small enclosure.
Overall, the geophysical survey has demonstrated that the footings of the hall survive to the east of the tower, accompanied by newly discovered enclosures with possible structural elements to the south and north-west. The extent of the site appears to extend beyond the visible remains with anomalies continuing into the kirkyard.
Dr Edward Impey, one of the UK’s leading castle experts and patron of the CST examines some C13 graffito can boost our understanding of castles.
As every castle book reminds us, the defences of most castles before the mid-13th century, and the buildings within them, were built of earth and timber. The perishable nature at least of the timber parts, and their replacement in many cases in stone (obviously) makes their structural detail hard to understand, although Robert Higham and Philip Barker’s Timber Castles of 1992, and their publication of Hen Domen (Montgomery) in 2000 achieve a great deal in this direction. As most evidence is archaeological, however, it tends to be confined to plans and layout. Herein lies the importance of this graffito, scratched into a re-used ashlar in the early 13th century and found during the excavation of the long-demolished donjon in the castle at Caen in 1966: it shows, in elevation, what is unquestionably a timber-framed castle, or part of one – either a ringwork or a motte.
The graffito re-drawn, omitting the underlying mason’s tooling and lines probably unconnected with the original image.
To begin our description with the mound on which the buildings stand, this is marked with a series of lines inclining inwards towards the top, which may be the draughtsman’s device to give it substance, or, possibly, represent baulks of timber covering the slope – a variant of the arrangement found for example at South Mimms (Hertfordshire) and elsewhere. To the extreme right, similarly striated, is what must be the counterscarp of the ditch, and springing from it, possibly propped by two trestle-like structures, is the bridge across it: this is of the so-called ‘flying form’ shown in the Bayeux Tapestry and found archaeologically at Hen Domen. At its top end the bridge abuts a tower, necessarily a gate tower, its side scored with the diagonal intersecting lines, probably representing cross-bracing of the form found in the bell towers at St Leonard’s, Yarpole (1195-6) and St Mary’s, Pembridge, of 1207-23 (both Herefordshire); variants are known in France and over forty post-medieval examples in central Europe. The arrangement is also shown in a carving at Modena cathedral, and in numerous 12th -and 13th– century bestiary illuminations of timber towers on the backs of elephants, prompted either by Pliny the Elder’s or the Books of the Maccabees. Siege towers could be similarly constructed, hence the French term beffroi.

Abutting the tower is the battlemented wall or palisade, composed of edge-to-edge vertical timbers, reinforced by a horizontal rail at top and bottom and by massive diagonal or ‘X’ braces, face-nailed to the uprights.
Inside the enclosure, our draughtsman has shown at least three buildings. The most prominent has a pitched roof terminating in finials, with a row of four round-headed windows under the eaves. Conceivably this was intended as a chapel, but the windows more probably belong to the clerestory of an aisled hall, as survive in the single-aisled hall of c.1160 in the castle at Creully, seventeen kilometres north of Caen, and has been inferred in the 12th-century timber examples at Leicester castle and the Bishop’s Palace at Hereford. In front are two lower buildings with pitched roofs, one carrying a finial.
To the left of the hall is a structure consisting of a vertical pole, a cross-bar at the top, propped by diagonal braces. At first sight rather puzzling, this is clearly identifiable as a crane or hoist, thanks to the dozens of near-identical examples in medieval images, conveniently gathered together by Günther Binding’s compendium of 2001. To the right of the pole hangs a rope, taut as if being pulled or winched downwards, and which is carried over the cross-bar and two faintly-indicated pulley wheels, beyond which it hangs down again and appears to be in the act of hauling a large timber into the air.
The value of the depiction can be summarised as follows. First, it may be the only contemporary representation of a timber-built motte-top or ringwork complex, and is valuable in showing the whole apparatus of palisade, battlements, bridge, gate tower and buildings within. Second, along with the Abbaye aux Dames capital, it is one of only two known representations of face-nailed ‘X’ bracing – an arrangement by definition untraceable archaeologically – which would have endowed the palisade with immense lateral strength and was perhaps widely used. Third, this may be the only contemporary representation of a Romanesque aisled hall – if that is what it is – within a castle. Fourth, as the battlemented platform at the top of the tower oversails its sides, forming a machicolation, it is one a number of images showing that such things did not derive from hourds, but were integral at least to timber towers long before appearing in stone. Fifth, while it has long been assumed that medieval defensive towers in timber were structurally akin to 12th- and 13th-century bell-towers, this is, apart from the Modena carving, the only one to actually show this to be so. Finally, although representing a well-known type, the crane certainly adds liveliness and interest to the composition.
Who the draughtsman was is, obviously, unknown. So is whether the graffito represents a real or imaginary place, although the inclusion of the crane, in use, could be taken as a hint that a particular site, where building works were under way, was indeed intended. What is clear is that it is not a picture of the castle at Caen, nor indeed of Creully, both of quite different form.
Let’s hope that this blog and the forthcoming article (in French) will encourage the identification of other wooden castles scratched in stone, and help with their interpretation and of excavated evidence in the future.

Bill Klemperer is the Principal Inspector of Ancient Monuments for Historic England – advising on aspects of national policy and casework around the country – especially the midlands where he is based in the Birmingham office. Here he talks about four important border fortresses he has helped save.
Altogether there are many hundreds of castles in the Welsh borders most of which are scheduled – protected by law under the 1979 ‘Ancient Monuments and Archaeological Areas Act, 1979’ and part of my job is to help look after them. One of my predecessors, the late Anthony Stretten, undertook a survey in the 1990s to identify those castles that would require most effort to save them for the future. A ‘top four’ emerged – all with significant stone buildings that required repairs – Wigmore Castle just west of the village in north Herefordshire, Hopton Castle in south Shropshire west of Leintwardine, Wilton castle on the River Wye at Ross-on-Wye, and Clifford castle further up the Wye just north of Hay-on-Wye. They have now all been repaired – but the solutions have been different in each case.
Wigmore. This was a case of state intervention. Following a collapse the then Secretary of State, Peter Walker, agreed to take the castle into public ownership – so it is now maintained by English Heritage as a free visitor destination. The ruinous state of the castle was an issue – with multi-phase buildings all higgledly-piggledy all over the place. Twenty years of careful excavation was going to cost too much and would have destroyed much of the later evidence in revealing the earlier phases. So a different approach was agreed – the walls would be consolidated as they were – and the site would retain its importance for flora and fauna – a stabilised place of wonder to be discovered and explored. This became the type site for ‘soft capping’ that now has become mainstream practice. The grass on the wall tops protects the walls from the weather and after twenty years is still doing a good job. Some limited archaeology was done to inform stabilising works,but these few trenches produced amazing findings – so do get the report to find out more
Wigmore Castle Excavation
Hopton castle. An impressive earthwork site with motte and bailey and later gardens and associated buildings are evident, and also the site of a nasty civil war massacre and siege. When I first saw it I was struck that the impressive tower of c.1300 that dominates the site could be abandoned in a field without access. A condition report revealed that the north west corner was about to fall off – but how to get the money to fix it? We talked to the locals and the Hopton Castle Preservation Trust was born. English Heritage funded a condition survey and work to prepare a lottery bid and the committee decided – by the Chair’s casting vote – to award about a million pounds! Archaeological ‘clearance’ followed and CBS Conservation came in to do the works. The Duke of Gloucester helicoptered in for the official opening. The site now has free access every day of the year and is secure for the future.
Hopton Castle Restoration – mini railway to clear rubble
Wilton Castle was done at about the same time as Hopton in the first decade of the millennium. Here the ‘White Knight’ solution came to the fore in the shape of owners Alan and Sue Parslow. Wilton is a multi-phase stone castle and much work was needed to repair the walls and towers. This was jointly funded by the Parslows and English Heritage. Various different conservation techniques were used – full roofs were put back on the north west and south west towers – the former complete with chimney found in the excavation of the basement! A ‘hidden’ lightweight modern roof put onto a large 13thC east tower. Gracile [DO YOU MEAN GRACEFUL?] walls were supported by buttresses in contrasting material, wall walks discovered and replaced, a section of curtain wall rebuilt, and decayed stone, including some lintels and cills replaced. The site is now safe and the owners have open days each year.
Wilton Castle Reconstruction Work
Clifford was the most recently repaired – and this came about when the site came into the new ownership of Keith and Ann Hill, who are also keen to care for the castle in their care. Historic England (as we became in 2015) gave a grant to help the owners repair the buildings on top of the motte and this was done by Treasures of Ludlow – a well-known firm of conservation builders. Archaeological interpretation of the buildings has been undertaken by Nigel Baker while the Castle Studies Trust funded a geophysical survey and excavations there too. Amongst the tightly packed stone buildings on the large flat-topped motte is the so-called Rosamund’s Tower. Rosamund Clifford – the ‘Rose of the World’ – was brought up at Clifford Castle, daughter of the Marcher Lord Walter de Clifford. She became the mistress of Henry II and died, still not 30 in 1176. The site with its large bailey containing remains of an interesting barbican can be visited by appointment with the owners.
Clifford Castle CST Excavation Study Day – chamber block on the mott
Much work has been done and much more remains to be done. The ‘local Trust model’ is achieving spectacular results at Snodhill castle near Peterchurch in Herefordshire’s Golden valley. Another notable success in recent years has been the repair of the rare shell keep at Kilpeck castle south of Hereford. All of these places are part of our shared inheritance Looking after them is our responsibility to future generations so they can share in that wonder.
William Wyeth, Properties Historian at English Heritage Trust and project lead on the Castle Studies Trust funded project to geophysically survey Warkworth Castle explains what he hopes the survey will achieve.
In 2019 English Heritage, a charity which looks after over 400 historic properties and sites across England, began a project to change the way in which the stories of the people and buildings at Warkworth Castle in Northumberland were told. The castle is a popular destination in the county, and is both connected with notorious figures from the past as well as featuring an iconic piece of medieval architecture and design in its late 14th-century Great Tower.

Warkworth is located at the foot of a narrow loop in the River Coquet, in coastal north-eastern Northumberland, about 25 miles north of Newcastle-Upon-Tyne and 30 miles south of Berwick-Upon-Tweed, themselves both significant fixtures of the late medieval history of this area. Just north of the castle proper and nestled on three sides within the river loop is the small village of Warkworth, arrayed in quite typical medieval layout. At the north end of the high street, sitting on a rough north-south axis, is the parish church of St Lawrence, probably an early medieval foundation, as well as a bridge with a toll-collecting tower built in the later 14th century. South of the church, numerous narrow parallel plots of land spread out at right angles from the high street. The southern trajectory of the street is abruptly broken by the enormous motte (earthen mound) of the castle, which acts to physically separate the village from the land south of the river.
Among the most famous historical figures connected to the castle was Henry Percy, eldest son of the 1st Earl of Northumberland, though he is more familiar to us today as Harry Hotspur. The origin of his martial nickname is not certain, but is accounted for in several traditions, all of which confirm that they drew from his short-tempered and violent character. One later 16th-century source rhythmically noted “For his sharp quickness and speediness at need / Henry Hotspur he was called in very deed.”
Though the early history of the Percy Northumberland earls and associated figures will form a key part of the story of the castle when the interpretation project is completed in 2022, other questions about the castle, and especially its earlier history, remain as yet unresolved. Among these is the relationship of the earthworks – the motte and bailey – with the stone structures atop them, the oldest of which date to the later 12th century. The Castle Studies Trust has graciously agreed to fund a geophysical survey of much of the castle earthworks to resolve three big questions.
The first touches upon the motte, which features the Great Tower of the 1370s, but was probably topped by an earlier structure. By assessing buried deposits around the tower, we aim to reveal traces of this earlier structure. But we also want to establish evidence for the means by which the Great Tower may have been provisioned, via a secure door to the motte-top outside the enclosing curtain wall which gave access to storage areas for beer and food in the tower’s north-west segment.
The second question relates to the bailey. In common with other castles of this type, the bailey was filled with buildings, often (as at Warkworth) in their earliest phases arrayed along the inner face of the enclosing wall. But were there buildings here before, or were there also buildings here from later periods, but for which above-ground evidence has been lost? Findings from the survey here will greatly influence how we understand the formal approach to the bailey’s principal buildings – its Gatehouse, Great Hall and Chapel – but also the late medieval Great Tower. The results may also shed light on the peculiar overhauling of spatial arrangements in the bailey occasioned by the construction of a 15th-century Collegiate Church which straddled the span of the bailey, arguably fundamentally changing how the castle was to be experienced.
The last question also relates to the bailey, but here to a strip of the bailey which sits outside the embrace of the late 12th-early 13th-century stone curtain wall, on the eastern side of the castle. The omission of this area from enclosure is unusual, though it is not without analogies from elsewhere, which suggest areas like this could contain gardens. It may be instructive that just within the bailey and adjacent to this strip was the location of late medieval stables – perhaps this area came to be used for the grazing of horses, though whether this was its original intended purpose remains to be seen. In addition to all of this, however, is the possibility that when the motte-and-bailey was built, perhaps well before the earliest stone parts of the castle were erected, the earliest enclosing wall of the bailey also embraced this eastern strip, thereby creating a larger bailey than the present one.
We hope that the survey will allow us to answer at least some of these questions. Whatever the outcome, it is certain that the results will help change how we understand the story of Warkworth Castle and its previous inhabitants.
Heidi Richards, doctoral research at Durham University, looks at Pendragon Castle and how medieval romance literature impacted later medieval castle building.
Since childhood, I’ve been fascinated by castle ruins, stories of King Arthur, and a golden age of chivalry that existed somewhere back in time between history and fantasy. Fast-forward twenty years, and I’m currently finishing my doctoral thesis looking at the impacts medieval romance literature had on late medieval English castles.
Former arguments in castle studies subjected castles into a martial vs. status dichotomy, but current research embraces the duality of these aspects of the castle, providing space to explore possible symbolisms built into castle architecture and wider landscapes.
My research explores the importance of romance literature and legend within medieval society’s most elite, and through wills, commissions, dedications, and gifts, we find that romances were highly valued. Of primary importance though, was Geoffrey of Monmouth’s (c.1138) Historia Regum Britanniae (History of the Kings of Britain). While not technically a romance, this work brought legendary heroes into an ancestral pseudo-history of the kings of Britain (including Constantine and King Arthur) and provided source material for romance narratives and characters. Many members of the elite alluded to this highly prestigious “ancestry” to legitimize and justify power, especially within the political propaganda and ambitions of Edward I.
Edward I was indeed an Arthurian “enthusiast” (as he has been called in previous research). He hosted many “Round Table tournaments” (more theatrical than regular tournaments and usually included Arthurian role-playing) to celebrate significant events, such as his Welsh victory in 1284. He exploited his “Arthurian ancestry” in a grand ceremony at Glastonbury Abbey in 1278 to reinter Arthur and Guinevere’s bodies—essentially conducting a spectacular funeral for Arthur, during which he used “Arthurian” relics (including Arthur’s crown) to legitimize his “inherited” power. He also wrote a letter to Pope Boniface in 1301 to claim land in Scotland on the basis that it was once owned by his ancestor, Arthur. A grand feast was also held at Westminster in 1306, during which Edward I swore oaths on a swan, in typical romance style, and knighted Edward II along with 267 others.
Every effort was made to continue Edward I’s Arthurian prestige and chivalric legacy when Edward II succeeded the throne. On his deathbed, Edward I charged his closest barons with assisting Edward II as his reign began; one of whom was Robert Clifford, who organized an enormous, chivalric celebration for Edward II’s coronation in 1308.
Edward II soon began to show that he was not the chivalric king his father was, staunchly contradicting the values of Edward I’s chivalric legacy. Records claim that he enjoyed working in the garden (which was uncustomary and inappropriate for a king), he didn’t like hunting, he didn’t participate in tournaments, and he thoroughly annoyed the barons with his infatuation over Piers Gaveston. As baronial unrest and tensions increased, we begin to see Arthurian allusions made by Edward II’s principal opponents—the same ones closest to Edward I.
This brings us to Pendragon Castle (Cumbria, previously Westmoreland), inherited by Robert Clifford as the “castle of Mallerstang,” along with other nearby castles, including Brough, Brougham, and Appleby. Clifford renovated Brougham and Pendragon Castles in preparation to host Edward I during the Anglo-Scottish wars in 1300, but whilst his other castles were renovated in contemporary architectural styles, Pendragon retained its archaic image. Architectural archaism was a trend in castle construction, used to symbolise continuation of power and ancestral prestige. In 1309, Clifford was granted a license to crenellate, changing the “castle of Mallerstang’s” name to Pendragon Castle.

In 1312, Guy Beauchamp, 10th Earl of Warwick, presided over the trial of Piers Gaveston, whose greatest crime, according to the commemorative Warwick ancestral “Rous Roll” (c.1484), was stealing King Arthur’s round table. The Earls of Warwick already had long-standing connections with Arthur and displayed romantic “relics” inherited from their “ancestors.” Robert Clifford and Thomas Lancaster also participated in Gaveston’s trial and execution, and in 1322, Lancaster signed a treasonous document to James Douglas in Scotland under the pseudonym “King Arthur.” In 1327 and 1328, Roger Mortimer, the lover of Edward II’s queen, Isabella, celebrated the marriages of his children by hosting multiple Arthurian themed Round Table tournaments in the style of Edward I, each lasting several days and sparing no expense.

In the wake of Edward I’s chivalric legacy, those who were closest to him (including Clifford, Warwick, Lancaster, and Mortimer) developed ways to emulate Arthurian prestige in their opposition to Edward II, and it is within this context that Pendragon Castle comes into view as one of several homages to King Arthur, Edward I, and the not-so-distant golden age of chivalry.
This year we’re funding investigations at Shrewsbury Castle, one of the most important castles along the Anglo-Welsh border. Nigel Baker told us how the work has been going.
Phase 1 of the Castle Studies Trust’s Shrewsbury Castle 2019 project is underway. Archaeological research is a long and painstaking process, so instant results are not to be expected – it must have taken a whole three hours to establish for the first time a number of simple but really fundamental facts about the hitherto-unexplored inner bailey.
Work started on Wednesday 8th May with the arrival at the castle of Tiger Geo, specialist geophysical survey contractors. Using ground-penetrating radar and resistivity, the lawns of the inner bailey interior and the slopes of the ramparts were gridded out and surveyed; the geophysicists never stopped, nor did the rain. But two basic conclusions emerged on screen from the raw data.
Tiger Geo doing sterling work despite the weather.
The first is that a ditch did once encircle the base of the motte within the perimeter of the inner bailey. This implies that the flat area within the inner bailey must originally have been a crescent-shaped area less than twenty metres wide from motte ditch to rampart tail.
The second conclusion is that there is, under the grass opposite and parallel to the standing early 13th-century ‘Great Hall’ (which houses a very fine Regimental Museum), another big building range backing onto the motte ditch. Given that the standing first-floor Great Hall was built as a royal chamber block (‘camera’) in the 1230s-40s, there is a possibility that a real Great Hall awaits excavation in the summer. But we’ve already answered one of the project’s main questions, ‘how was the inner bailey planned?’ The answer is there were two main ranges of buildings and no room for anything else.
While Tiger Geo mowed the lawns, the writer was busy in a bush at the base of the motte, freeing-up a manhole cover sealed for a decade. Under, a 20th-century brick inspection chamber gives access to a stone well-shaft alongside. The writer had been shown it surreptitiously by a kind gardener in the 1990s but without the opportunity for much recording. Now it has been photographed (though not with stunning competence), measured at just over seventy feet deep from ground level down to water level, and the masonry identified as probably late medieval – and not something done by Thomas Telford in the 1790s. So – Shrewsbury Castle retains its medieval well.
The medieval well. It’s a dizzying 21m down to water level.
