Situated on Dun Beag, a precipitous local summit SW of the main bulk of An Dun, this fort has a single stone wall between 1.5m and 2.7m thick enclosing an area measuring 95m from NE to SW by a maximum of 50m transversely (0.31ha). The wall can be traced most of the way around the summit area, only disappearing along the precipitous slopes on the NE. Elsewhere along the NW the line of the outer face is almost continuous, in places towards the N and S ends standing as much as 1.7m high in ten courses. The entrance is at the southern end of the NW side, facing NW but essentially on the W of the interior. The only features visible within the interior are two shieling huts at the SW end, one of which has an attached enclosure.
