A ruined building is located on the edge of Cefn Bryn, just inside enclosed land on its northern slopes. It measures 19m (NE-SW) by about 3.6m and comprises two, possibly three, compartments of mortared, uncoursed rubble walling up to 2m high and 0.5m thick. Uneven ground to the north and east suggests ploughed-out ancillary structures and enclosures. The building is depicted on Ordnance Survey maps.
