Summary

The heavily vitrified dun on the summit of this rocky promontory possibly occupies the site of an earlier promontory fort. The dun measures about 12.5m in diameter within a wall reduced to a thick band of rubble with large masses of vitrified core. Some 14m to the N, set on the leading edge of a terrace below the level of the summit, there are also traces of a wall blocking the easiest line of access from the NW. While this may be an outwork to the dun, it betrays no sign of vitrifaction and is possibly the remains of an earlier promontory fort. If so, its interior may have measured at least 35m from N to S by between 9m and 18m transversely (0.04ha), though the greater part at the S end is now occupied by the dun. The position of the entrance is not known and the only feature visible within the interior is a stony scarp cutting across from E to W. Other fragments of crude walling were identified by the OS blocking gaps in a ridge of outcrop to the W and crossing the gully that separates this ridge from the W side of the of the promontory; they also identified a possible cistern, but the relationship of the dun and possible fort to any of these features is not known.

Investigation History

Although included by Richard Feachem in his Guide to Prehistoric Scotland (1963, 127), it is not clear whether his brief description is based on a field visit.

Investigations:
Earthwork Survey (1880):   Sketch-plan and description by Edward Hamilton (1880, 238-9, pl 1)
1st Identified Map Depiction (1899):   Annotated Vitrified Fort (Remains of) on the 2nd edition OS 6-inch map (Inverness-shire, Mainland, 1900, sheet 135)
Other (1968):   Visited by Helen Nisbet (photographs in RCAHMS collection)
Other (1970):   Surveyed at 1:2500 by the OS
