Summary

Large univallate contour hillfort located in high, elevated, and commanding position on steep-sided hill at end of Greensand spur just W of River Sid. Steep to very steep surrounding slopes. Measures c. 500m long with maximum width 100m, aligned SE-NW. Long, narrow pear-shaped with wider part at SE and encloses c. 4ha. Single earth rampart and ditch with counterscarp enclosing flat interior with quarry hollow. Rampart to 1.2m high, nearly vertical on inside, using steep break of slope on all quadrants varying between 4.4m and 9.6m externally. Outer ditch 2.9m wide and 1m deep. Counterscarp to 1m high merging with natural slope. Single elongated passageway entrance to NW formed by twin extension of ramparts at NW end producing bottleneck passageway c.100m long which has sunken appearance. Scarped platform overlooking hillslope to W would appear to have provided additional cover for W approaches to passageway. At least one hoard of sling stones found in 19th century. Banking forming enclosure in interior at SE corner and two ponds modern. Pasture interior, wooded surrounds. Well-preserved. On 1st Ed. OS map (1889). Undated.
