Summary

The remains of a fort occupy the crest of an isolated rocky ridge that rises out of an area of moorland E of Kilbride. Irregular on plan, it measures about 50m from E to W by a maximum of 20m transversely (0.1ha) within a wall reduced by stone robbing to an intermittent band of rubble about 2m in thickness extending around the margins of the summit. Several runs of outer face can be seen around the circuit, and on the SE one of inner face, this latter indicating that in places the wall may originally have measured as much as 4m in thickness. No trace of the entrance is visible, but on the SW a pathway leading up between the outcrops may indicate its position. Traces of cultivation rigs can be seen within the interior, and on the very highest point there are also traces of a stone-revetted platform.

Investigation History

First depicted in 1878 on the 1st edition OS 25-inch map (Argyll and Bute 1882, sheet 232.10), it was surveyed at 1:2500 by the OS in 1979, and in greater detail that same year by RCAHMS for the County Inventory of Argyll (RCAHMS 1984, 75-6, no.127). It was Scheduled in 1993.
