Small, rocky, oval partial contour hillfort located 1.7km from Foel Drygarn (Atlas No 1895) on the lower slopes of the Preseli Hills. Moderate to strong on N, and W, steep on S, precipitous on E. Roughly triangular enclosure measures c. 66m N-S by 38m, with internal area 0.19ha. Defined by simple dry-stone wall, with no evident ditch, incorporating rock outcrops and fronting onto precipitous slopes of Carn Alw on E. Some facework still visible, but now mostly collapsed stone. Site notable for its fine chevaux de frise to SW and W sited in an arc around the entrance with stone-lined pathway. No signs of habitation, but evidence of many enclosures, huts and fields in the area. Small enclosures on either side of the entranceway probably medieval or later. Carn Meini, the source of the Stonehenge 'bluestones' is due S. Extensive and associated complex of features SE-NW about site. Tumbled stone walls and scree in extensive rough moorland. Minimal investigations, undated.
