Summary

This small fortification stands in a spectacular position on a rocky ridge that falls away 150m down to the SE shores of Loch Ness. It occupies the very summit of the hill about 80m NE of a second fortification (Atlas No. 2882) and is oval on plan, measuring about 26m from NNE to SSW by 15m transversely (0.03ha) within a ruined wall spread up to 5m in thickness by 0.8m in height; the outer face is visible on the E. In 1957 RCAHMS investigators observed numerous pieces of vitrifaction in the rubble, but no trace of this was subsequently found by the OS. The interior is featureless apart from a hollow 2m across on the SW that may be a well. The entrance is possibly on the SSE.
