A single massive rampart crowns a visually distinctive, flat-topped hill, creating a roughly triangular enclosure, about 300m east-west by 180m, the group falling away steeply on all sides but the east, an entrance at the north of this eastern facade is elaborated by a 'barbican' outwork about 24m across.
Investigation of eroding sections has suggested an Iron Age date for the enclosure.

An inner enclosure, measuring approx. 190m by 70m, encircling the summit of the hill was discovered by Bryn Gethin during analysis of aerial photography in 2010.
