This ruined castle dates back to the 14th Century. The castle comprises a courtyard about 80 feet square, with surrounding granite walls, 8 feet thick and 20 feet high. Square towers project from three sides while a formidable gatehouse is the feature of the fourth. Access from the road via a small timber footbridge.

The interior of the castle is now bare but originally featured two-storey structures built up against the inner walls. The castle was most probably built by Roger Bigod or by a member of the Carew family.
