Summary

This fort is situated on a precipitous promontory formed as a wave-cut platform at the foot of the coastal cliffs at Garrisdale. Its defences comprise a single wall up to 3m in thickness, which has been drawn across the neck of the promontory on the SE over a distance of a little over 40m. Its outer face is composed of massive blocks and stands about 0.8m high in two course; the smaller boulders of the inner face have been laid in rough courses. Outside the wall there are traces of a possible ditch entering the gullies to either side, and the entrance lies slightly SW of the mid-point of the wall. The irregular interior, which measures about 130m from NE to SW by 80m transversely (0.78ha), is largely featureless, though there are traces of a rectangular building about 10m in length by 2.7m in breadth internally set against the inner face of the wall. A second smaller building is set against the outer face of the wall, overlying what are probably an earlier turf structure reduced to a mound some 16m in length, which has obscured the line of the possible ditch in this central sector.
