Summary

A heavily vitrified dun occupies the summit of a promontory which is also cut off on the landward side by the remains of a wall drawn obliquely across its relatively narrow neck. The dun measures about 12.5m in diameter within a heavily vitrified wall in the order of 5m in thickness, and there is another heavily vitrified wall forming a small annexe on a lower terrace on its SW flank. The outer wall barring access to the promontory from the S is reduced to little more than a band of rubble spanning the neck between two clefts in its rocky flanks and extending a little way along its SW margin; a single small mass of vitrifaction has been observed amongst the rubble, and there is a gap for an entrance towards the W side. To its rear the promontory is roughly triangular on plan, measuring a 100m from N to S along its E flank by a maximum of 60m transversely (0.39ha). The relationship between the dun and the wall across the promontory is unknown.
