Contour hillfort sited on exposed, rocky and isolated summit above Llyn Cynwch to NE and one of a cluster of small univallate sites near Dolgellau above the confluence of the Afon Mawddach and Afon Wnion to W (see Foel Offrwm - Atlas No. 1780), in particular). Very steep and precipitous in places surrounding slopes. Measures 70m NE-SW by 42m with internal area 0.21ha. Stone wall in ruinous state c. 2.7m-3m wide at its base constructed in short straight lengths around the hilltop. Possibly around 2m high when original. Best on N side. Deliberate slighting has been suggested (Bowen and Gresham 1967, 153). Simple gap NE corner entrance. One wall purposely thickened to increase the length of the passage, and protected outside by a mound and ditch. Moorland and rough grass and bare rock. Well-preserved for stone-walled site despite tumbled condition. On 1st Ed. OS map (1889). Minimal investigations, undated.
