Summary

Traces of a small fortification can be seen on a rock boss close to the shore at Ballyhaugh. The boss falls away in cliffs up to 12m high everywhere except the N, from where the summit is accessible across a series of terraces that ascend the NW flank. At various points around the lip of the cliff traces of a wall can be seen, enclosing an area measuring about 29m from NW to SE by 26m transversely (0.06ha), while an outer wall has probably enclosed a lower terrace on the N. Nothing can be seen of the entrance itself, though the topography dictates that it was on the NW, and there are no visible features in the interior, which is largely bare rock.
