Summary

Large univallate contour hillfort straddling E-W spur leading from Broad Down plateau and overlooking valleys of tributaries of River Coly, a tributary of River Axe. Steep to very steep slopes to N and S, moderate to E and W. Oval area encloses c. 1.3ha. Defined by bank and outer ditch c. 1.8m high internally and 4.8m high externally. Ditch to 1.1m deep. Traces of quarry ditch. Interesting S entrance with barbican, possibly secondary to main enclosure. Three modern entrances, each with causeway. Excavation by P.O. Hutchinson 1869 and under auspices of Devon Exploration Society by A. Young and K. Richardson 1952-54. Latter found hut site, trenches, cooking pit and clay oven base. Also early and middle Iron Age pottery (largest published ceramic assemblage from a Devon hillfort), iron slag, over 1000 slingstones, four whetstones, two spindle whorls, bronze fragments and worked flints. Two rectangular building platforms against the inner face of rampart possibly medieval or post medieval buildings. Rough grass interior with large scattered trees and some scrub. Well-preserved site. On 1st Ed. OS map (1889).
