Summary

Univallate partial contour hillfort located on downland spur promontory of Castle Hill facing NW with far reaching views towards River Thames lowlands and its confluence with the River Ray at Cricklade. Moderate surrounding slopes N, E, W, level to moderate on S. Andrews and Dury's Topographical Map of Wiltshire 1773. Site measures c. 250m by 150m aligned approximately NW to SE, roughly triangular in plan with the NW side forming a rounded angle, enclosing 3.5ha. S and W sides defended by bank max. 15m wide. Beyond this ditch 20m wide with substantial counterscarp bank (particularly strong on SE and SW) with crest 4.5m above base ditch. Moderate slopes to NE have slight internal bank. Break in earthworks at the SW and SW angle of probably original entrance. Number of probable storage pits revealed during magnetometer survey during 2004. Colt Hoare recorded possible causeway descending NW from hillfort now thought to be medieval reuse of ditch as trackway. Low earthworks within SW corner possible remains of occupation. Ramparts on NW levelled to form several lynchets, most probably during medieval period. Possible early Iron Age pottery found on S side of rampart. Downland pasture. On Ist Ed. OS map (1886).
