Summary

The remains of a small fortification are situated on a promontory above the rocky foreshore on the W side of the beach in Achnahaird Bay. Its defences comprise two main elements: an outer wall 2.6m in thickness drawn in an arc across the neck of the promontory on the SW; and an inner wall 3m in thickness set square across the promontory some 7m to its rear. The interior of the promontory to the rear of the latter measures about 18m from NE to SW by 5.5m transversely (0.01ha) and was probably enclosed by a slighter wall up to 1.5m in thickness, though this only survives on the NW flank. The remains of the two walls across the neck on the SW were initially interpreted by Alan Ayre of the OS as the remains of D-shaped blockhouse, but later work by RCAHMS regarded the outer as an outwork to a dun; the RCAHMS investigator also suggested that the outwork butted onto the inner wall, though a photograph held by Highland HER showing the junction on the W suggests that it is too ruinous to be certain on this point; likewise the assertion that a dip in the crest of the wall marks the position of a central entrance with a possible door-check on the NW side of the passage.
