1. Fragmentary but substantial walling, possibly remnants of a rectangular building, c.14m by 10m, on the narrow isthmus of land between North and South Haven. This may be the remains of a medieval chapel reputed to have stood somewhere on Skomer Island. The position overlooks one of the most likely harbourages for historic visitors.
