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.
With HES giving the provisional sign off for the excavation at The Wirk to take place in the week commencing 21 September, and the geophys survey to take place the previous week, project leads Drs Dan Lee and Sarah Jane Gibbon outline the background to the project and what they hope to find.
Located on the south-western coast of Rousay, The Wirk is located in one of the most archaeologically rich parts of Orkney. The Orkney Research Centre for Archaeology (ORCA) is undertaking geophysical survey, archaeological excavations and 3D modelling at this enigmatic castle site (pending approval from HES).
The Wirk, meaning stronghold in Old Norse, and with the alternative name Westness Castle, is a small stone tower located close to the coast. It has variously been interpreted as a 12th century Norse Castle, a detached fortified bell-tower, a 13th century defensive tower for an incomplete church, a hall-house garderobe tower and most recently a 16th century tower and attached range.
Minor clearance and excavation in the 1920s identified similarities in construction between The Wirk and the 12th century Cubbie Roo’s Castle, on the nearby island of Wyre, considered to be one of the earliest stone keeps in Scotland. The Wirk is located in Westness which has been a large estate since at least the 12th century when it was the home of the Norse chieftain Sigurd of Westness (Orkneyinga saga). It is adjacent to Rousay parish church, likely to date from the 12th century, with standing remains of 16th century date on earlier footings.
Recently, the 12th/13th century date attribution of The Wirk has been rejected in favour of a 16th century date. This new interpretation is based on the built remains and 16th century architectural fragments which were found in the 1920s. However, architectural fragments of 12th/13th century date were also present and nearby archaeology, particularly the discovery earlier this year of a Norse hall at Skaill by the UHI Archaeology Institute would suggest this was a high-status place in the saga period. This is not to dispute that The Wirk may also have been in use in the 16th century when the estate was owned by a prominent Orkney family. One of the objectives of this project is to excavate trial trenches over Clouston’s excavation and at the eastern end of the site to identify the earliest phases of the tower and adjacent building. Upper parts of the tower were substantially rebuilt in the 19th century and so excavation will allow us to record parts of the site that have not been knowingly rebuilt.
Along with the excavations, targeted geophysical survey around The Wirk aims to better understand any relationships between the tower and the buildings/features which surround it. 3D modelling of The Wirk and Cubbie Roo’s Castle will enhance our understanding of these comparable sites and allow the public to explore the remains online.
Research on castles has outgrown the walls of architecture, sprung from the rubbly tangle of archaeology and taken flight from the pages of law texts, charters and literary exposition. In the hands of an adept writer, these are small bumps on the road to timely completion. Presently, however, I find myself in the camp of the almost-complete thesis writers (PhD fourth-yearers: here is fellowship!). It is a credit to castle studies that there is so much to think and write about and, perhaps, get lost in. This post shares some of the most interesting conclusions from my work looking at early stone castles in two polities in medieval Scotland, the Earldom of Orkney and the Lordship of Galloway. Among the themes I examined was the transition from timber to stone architecture, the relationship of castle to landscape and the political context for castle construction in these areas.
Why Orkney and Galloway? To begin with, we cannot be certain why castles appeared in non-‘feudal’ Orkney in the first place. Secondly, one of Orkney’s early castle sites, according to accepted wisdom, is the prototype for a larger group of early castle sites in the earldom – and has influenced larger debates on castles in Scotland more generally. Cubbie Roo’s Castle, this foremost plank of Orcadian castellar wisdom is, I believe, a little younger than widely believed. Nevertheless, the evidence suggests Orkney was probably home to a stone castle founded around the middle of the 12th century, decidedly early for this part of the world.
If the castle site (but not the surviving architecture) is genuine, then the attendant landscape must be examined too, for Cubbie Roo’s and other Orcadian castles. Following a conventional model of castle as the centre of lordship, one would expect to find churches and important farm sites close to suspected or documented castle sites. This was simply not the case in Orkney. Cubbie Roo’s and the other castle sites I examined were, on present (chiefly place-name) evidence, sited on marginal lands of indifferent quality. Some preserved evidence of associated chapel sites, which fits with the conventional model of early castellar lordship.
The disconnect between terrestrial wealth and castle location opened three possibilities about the origin and siting of castles: firstly, were these defensive sites? If defence included a consistent grasp of the surrounding area, including major seaways through the Earldom, then the answer is no. Secondly, were these sites connected to maritime wealth? It is entirely plausible: recent research has demonstrated the wealth of the earldom derived massive fisheries exploitation. Thirdly, were these sites connected to ‘new’ arrivals to the Earldom? The political upheavals in the Kingdom of Norway (to which Orkney belonged) saw magnates appear in the Earldom with no obvious familial connection. The lack of obvious relationship with good farming land may be taken to suggest the castles were built on land acquired more for the purposes of castle building (and architectural showmanship) and maritime exploitation than the inherent wealth of the soil. The new men’s power derived from proximity to the Earl, not a direct ancestral claim to a portion of Orkney’s economic output. Orkney’s earliest castles, whatever their form, were the product and reflection of a shift in how comital wealth and power operated.
Galloway’s castles present a different challenge; though as a group they are more numerous than their Orcadian counterparts, the evidence for them is drastically more erratic. The exquisite (and displaced) Loch Doon Castle is more clearly understood than the hummocky mound of Castledykes outside Kirkcudbright, for example. On a cursory examination of both sites’ landscapes shows that Castledykes is much easier to understand. Kirkcudbright was the centre of the powerful Lordship of Galloway. Its hinterlands feature no fewer than three monastic foundations by the Lords, and the probable extent of demesne estate concentration in the area around Kirkcudbright is one of the highest in the Lordship.
What of Loch Doon Castle? Any modern visitor will appreciate the eponymous loch is remote and difficult to access from the big towns of Scotland’s south-west. However, it was originally built on an island in the Loch and later dismantled and reconstructed on the shore. It initially sat on a substantial route-way between the Glenken in Galloway – another demesne area of the Lords – and the Scottish coastal royal burgh and castle of Ayr. Another route south of Loch Doon offered access to the southern area of Carrick and, via the River Cree, the Wigtownshire portion of the Lordship of Galloway, with its probable administrative centre at Cruggleton Castle. Though its landscape is presently dominated by fishing holiday cottages and forestry, place-name evidence suggests in the medieval period the area was exploited for its pastoral suitability, and analogous documentary evidence from monastic sources hint at mineral wealth too. Doubtless Loch Doon Castle also formed an upland centre in Carrick in counterpart to the lowland, maritime-oriented centre at Turnberry Castle (also surveyed during this project).
Lastly, an overview for all of Scotland. A small, prefacing section of my thesis examined the monuments record for all possible castle sites in Scotland, including the sites above and less conventional secular power centres in the 12th-14th centuries – palaces, enclosures, crannogs (artificial islands in lochs), duns and brochs. A growing body of evidence in Scotland suggests many sites typically understood as prehistoric (chiefly the last three aforementioned categories of sites) were re-occupied during the broad medieval period. One conclusion from this country-level study suggested that there were more medieval power centres (e.g. bearing evidence for occupation) per square kilometre in the western counties of Scotland than the east. This likely reflects the underlying patterns of early medieval lordship in Scotland over which the culture of castles was overlain. This may act as another, belated, nail in the coffin of the military-architecture thesis of castle studies in Scotland.
The framework of understanding castles through landscape as much as architecture and archaeology is one I hope to apply more widely to Scotland and, as I engage more fully with English castle studies in my new job, in the wider medieval world.
