Summary

Isolated rocky partial contour hillfort located high on a hillock above the Afon Conwy valley at 410m O.D. on the mid slopes of Tal y Fan. Moderate to strong surrounding slopes. Two lines of encircling defence, outer circuit encloses oval area, c. 78m E-W by 66m, with area 0.5ha, inner circuit wall enclosing oval area, c. 50m E-W by 42m with area 0.21ha. Outer being a bank of earth with an external ditch, which reaches a maximum height of 3m+. Stone revetment of laid masonry can be traced on the NW outer face, and a slight counterscarp bank on S. E side merges into the natural slope. Inner circuit heavily robbed stone wall c. 4m-5m wide. Simple gap through both ramparts on the SE but badly damaged. Hut circle can be traced against the inner face of the NW side of the inner enclosure. Rough upland moorland, gorse, scrub and bare rock. Minimal investigations, undated.
