Dunscaith gets its name from Sgathae, a legendary Queen in the days of Fingal. The ruins lie on the west coast of Sleat, the most southern peninsula on the Isle of Skye. The castle stands on a rock about 40 feet high, some 20 feet from the mainland. There was once a walled bridge connecting the castle to the mainland. The bridge led to a drawbridge, beyond which were stairs leading to the castle.
