Summary

This fortification encloses the summit of an elongated stack situated above the beach on the E side of the bay named Suileabhaig. Irregular on plan, the interior is largely defined by cliffs around the NNW end and the seaward flank, but along the more accessible NE flank is defended by a wall up to 2.2m thick; few inner facing-stones are visible, but stretches of the outer face can be seen and in some places this stands 0.5m high in several courses. The entrance is in the middle of the NE side, where the wall skirts the lip of a deep natural hollow in the side of the stack, and the NW side of the gap is formed by a single massive boulder 1.2m high. The interior measures about 61m from NNW to SSE by a maximum of 25m transversely and contains two structures within its SSE end, though both appear to overlie the wall. One is a small bothy and is probably associated with three similar structures at the foot of the stack below the entrance, while the other is an oval enclosure measuring 7.2m from N to S by 5.3m transversely within a wall 1.1m thick by 0.4m high.
