Sub-oval small hilltop isolated contour fort located on Mynydd Maendy, a prominent spur overlooking the Afon Rhondda Fawr. Very steep slopes on N, steep on S and moderate on E and W. Multiple enclosure with an outer enclosure, measuring c. 110m N-S by 98m of 0.9ha, has rubble bank, to c. 9m wide and 1.5m high where best preserved, with external ditch, clear on the W. Bank decreases to S and hardly seen on NE where slopes steeper. E part of site sub-divided into inner enclosure of c. 51m N-S by 36m, 0.19ha, with wide gap to SE, also with rubble banks, but lower than interior enclosure ramparts, but any ditch not defined. SE inturned passage entrance c. 4.5m long and 2.5m wide. Excavation, in 1901 (Williams 1902), revealed little of hillfort, finds generally associated with a low cairn sited within. Nine smaller mounds also in interior, nature and date unknown. Rough grass and scrub. On 1st Ed. OS map (1877). Undated.
