Summary

Small contour hillfort in a commanding position on a small rocky knoll above the Aber Gwyrfai at the lower end of the Aberglaslyn Pass in Snowdonia. Steep surrounding slopes and precipitous on S. Remains of stone wall c. 3m in diameter and 0.2m-0.75m high, follow circumference of the knoll, overlain by modern stone wall (which has used the earlier stone wall for material) obscuring inner face, enclosing 0.14ha. Outer face of prehistoric wall generally lies some 1.5m outside the later wall. No ditch. E entrance. Rocky and grassy moorland. Stone much robbed for modern wall. On 1st Ed. OS map (1889). Minimal investigations, undated.
