Set on the ridge of Mynydd Maendy, is a sub-oval enclosure, c.110m N-S by 98m, defined by a rubble bank with an external ditch. The E part of the enclosure is sub-divided about a slighter oval work, c.51m N-S by 36m, also defined by rubble banks.
Excavation, in 1901, revealed little of the enclosure complex, finds being generally associated with the cairn (nprn 307643) found within it (Williams 1902 (AC2), 252-60).
