Summary

Univallate contour hillfort located in commanding position at S end of narrow steep sided ridge-backed hill situated between the River Yarty and the River Axe. Steep slopes NE to SE, moderate to strong S, W and less to N. Elongated in plan, measuring c. 225m N-S by 60m, enclosing c. 1.3ha. Defined by earth/stone rampart with chert facing around circuit. To W 5.8m wide with angled outer slope littered with the chert blocks; internally bank near vertical 2m high. On E bank lower and incorporated in later hedge bank, and steep natural defences here suggest scarping of natural hillside rather substantial rampart. Ditch no longer visible. Quarry hollows along inside of W bank and elsewhere. Had effect of creating raised and domed area towards centre of the hillfort, best on N part of interior. Three entrances, one modern on N. Possible original entrance at SW corner where S rampart terminal projects forward and outwards giving gap 3m wide gap. Another on NE side more problematical as much altered and rampart part levelled, with small enclosures placed just within the rampart of probable modern origin. Improved pasture interior, line of trees surround site. Fair condition. Minimal investigations, undated.
