Architecture, archaeology and continuing use
Rubble walls with yellow sandstone dressings form a rectangular main tower and smaller stair jamb. A vaulted ground floor, scale-and-platt stair, great-hall fireplaces, gunloops, corbelled turrets and an eroded armorial panel survive despite the loss of floors and roof.
Its story
Patrick Stewart began the castle in 1599, reportedly compelling islanders to provide unpaid labour. It served as residence and judicial centre, later housed Commonwealth soldiers and was associated with Shetland’s witch trials. Archaeology around the tower indicates ancillary buildings and seventeenth-century activity.
Why it is included
Scheduled status recognises a rare Shetland castle, an unusually complete late tower house and its potential to illuminate elite power, justice and domestic life.
What to notice
- The square stair jamb joining the larger rectangular tower.
- Quatrefoil and circular gunloops around windows and entrance.
- The weathered armorial panel above the doorway, viewed from a safe public position.
