Kelspoke Castle

Kelspoke Castle stands as a ruined tower house above Kilchattan Bay on the Isle of Bute. The remains sit on a low cliff overlooking the water, with views across the Firth of Clyde. Built from red sandstone, the structure once formed an L-shaped plan typical of 16th-century Scottish tower houses. Very little now rises above ground, but the outline of walls and foundations can still be traced. The site occupies a quiet stretch of coast on the island’s east side, far from the main town of Rothesay. The castle’s history is poorly recorded, with no exact date for its construction. Archaeologists believe it may have been built in the late 15th or early 16th century. The main block measured only six metres by six metres, while a projecting wing extended sixteen metres by five metres. Today the tallest standing piece is a stub of wall just over a metre high in the north-east corner. Grass now covers most of the ruins, but the shape of the building remains clear against the turf. Visitors reach the site along a short path from the road above Kilchattan Bay. The ruins occupy a small fenced enclosure, with information boards explaining what once stood there. From the cliff edge there are wide views over the bay and across to the Ayrshire coast. The surrounding area is peaceful, with few other buildings nearby. The castle’s modest remains offer a quiet reminder of Bute’s medieval past.
