A platform is located above the west side of Afon Llia within a triangle formed by three neighbouring Bronze Age monuments (84539, 84541 and 84544).
The embanked platform measures 8m (N-S) by 6m, is cut back on the west to 0.5m high and defined on the north and east by a 3m wide bank 0.2m high. The site lies equidistant from Maen Llia and concentric 'hengiform' earthwork within the triangle and thus is probably related to them.
