Summary

Overlooking the village of Letcombe Regis on the chalk escarpment with the Ridgeway nearby to the S, a roughly circular contour fort of c.10.7ha. Mentioned in Aubrey's Monumenta Britannica (1665-1693), on Roque's map of 1762. Univallate with ditch for the entire circuit, cut by road creating breaks through the rampart to N and S. Out-turned entrance to the E with hornwork, possible blocked entrance to the SW. Has been deeply ploughed in the interior, ramparts in good condition. Geophysics by English Heritage (Payne et. al. 2006), excavation in the interior, rampart and E entrance in 1996 and 1997 (Lock et. al. 2005). Evidence for pits, roundhouses, environmental, artefacts, dated to c.600 - 200 BC from stratified pottery. A study of the wider area suggests considerable pre- and post-hillfort activity (Levick 2015).
