Freswick Castle is a 17th-century fortified house incorporating an earlier tower, standing above Freswick Bay on the Caithness coast between Wick and John o'Groats. It is a private estate and not open to visitors, but the exterior can be seen from the road and beach. The bay below the castle is one of the better-preserved Norse settlement sites in Caithness, with a significant Viking-era midden (rubbish heap) that has yielded important archaeological finds. The castle itself presents a handsome, somewhat austere facade above the bay.
On the A99 between Wick and John o'Groats, at Freswick Bay. Approximately 6 miles south of John o'Groats.
