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.
