Large, excavated contour hillfort, now part-quarried away, located on summit of NE-SW volcanic ridge commanding the River Severn valley (River Severn 1.75km away) above its confluence with the Afon Vernwy. Surrounding slopes N and W precipitous, S very steep, E moderate to strong. Near Bausley Hill (Atlas No 1197), Cefn-y-Castell, Middletown Hill (Atlas No 1198) and New Pieces (Atlas No 1536) hillforts. Measures c. 1,150m long by max. 250m across, with internal area c. 28ha. Defined by two or three widely-spaced stone-revetted ramparts on the SE side, with a centrally placed entrance, elsewhere defined by precipitous slopes. The strong stone inner bank is revetted to front and back, with weaker outer bank. Further strong outer bank with outer ditch and traces of counterscarp. Excavations between 1933-5 and 1969-73, prior to quarrying, showed occupation from late Bronze Age to the fourth century AD, with ramparts substantially intact at the latter period (O'Neil 1937; Musson 1991). Forty C14 dates and dateable finds suggest late Bronze Age construction of primary rampart with end of Iron Age occupation in first millennium BC. Environmental evidence from the summit Buckbean Pond showed extensive seasonal occupation (Buckland et al. 2001). Lesser defended enclosure, with associated field system c. 270m to SE. Many roundhouses and four-posters. Finds indicated metalworking, spinning and weaving and leather and wood working. Important finds from pond and its associated cistern included wooden sword and bowl. Later Roman rectangular structure. Rodney's Pillar monument to Admiral George Brydges Rodney on summit. On 1st Ed. OS map (1886).

Excavations showed occupation from late Bronze Age to the fourth century AD. Later Roman rectangular structure. Forty C14 dates give construction of primary rampart to 990-860 BC tpq, refortification 470-340 BC, hillfort end 190-80 BC (Horn Forthcoming). Four dateable brooches and metalwork of 1,000 BC-700BC date.
