Summary

This fort, which occupies the summit of a steep-sided hillock overlooking Lochranza is oval on plan, measuring about 70m from ENE to WSW by 35m transversely (0.2ha) within a single wall reduced to a band of stones about 3.5m thick around its S margin. No entrance is visible and it probably lies at the junction between the wall and the undefended N flank of the hillock on the E or W. The interior is featureless.
