Large, high, univallate, contour enclosure located on the narrow summit NE-SW ridge of the prominent Llysin Hill, overlooking the River Aran, a tributary of the River Ithon. Steep surrounding slopes on NW, precipitous on SE, more gentle on NE and SW. Roughly D-shaped in plan measuring c. 80m ENE-WSW by 45m, with internal area 0.84ha. Single weak bank around most of circuit to 0.9m high maximum, but only a trace in parts of S. Discontinuous shallow outer ditch, in places only a terrace on NW, and non-existent on SE. Possible traces of quarry scoops to WNW. Two outer earthworks of bank and ditch on NE 85m and 95m from fort may be outworks associated with a possible entrance, 11m wide probably widened subsequently. Entrance gap to 4m wide without elaboration on S possible entrance, but uncertain. On 1st Ed. OS map (1889). Rough grazing and denuded by ploughing. Not scheduled. Minimal investigations, undated.
