Summary

This small fortification occupies the summit of a rock stack which stands some 6m above the level of the headland on the W side of Port Mor. Its defences comprise a single wall extending around the margin of the summit to enclose an area measuring about 31m from NW to SE by 27m transversely (0.07ha); the wall ranges from 2m to 4.5m in thickness, with extensive runs of both inner and outer face, the latter up to 1m high in five courses. The entrance is on the E, where a narrow cleft provides access to the summit and the N terminal narrows and the outer face turns inwards slightly above it. Two Rectangular buildings with rounded angles lie in the NW end of the interior, the rest of which has been cultivated as a plot of lazy-beds; the latter override four shallow scoops, three of which are set immediately behind the wall and may be contemporary quarries. A fragment of a saddle quern lies amongst tumbled rubble from the wall on the NW. What at first sight appears to be an outer wall built across the headland at the foot of the stack on the N is probably not defensive and may be associated with the later occupation of the site.
