Summary

Bivallate partial contour hillfort located in easily defensive position on domed summit of hill forming notable landscape feature within Ministry of Defence Salisbury Training Area. Sub-trangular shape enclosing 7ha. Defined by bank and ditch with additional bank on SE side. S section well-preserved. Constructed on site of Neolithic settlement discovered during excavation in the 1950's of section of SE rampart (Megaw 1967). Number of flint flakes and tools recovered. Also partially excavated in 19th century (no details). Pottery sherds and artefacts found. Sited at centre of late Bronze Age/Iron Age boundary complex. Straight, well-defined boundary earthwork of ditch/bank/ditch extends from the NW main entrance; one element of extensive system of boundaries found on the hill suggesting late Bronze Age interest. Four modern gaps result of tank track damage and 19th century gravel digging on W side. Interior badly damaged by gravel digging. Planned by Colt Hoare 1810 and on 1st Ed OS map (1887).

Investigation History

In Aubrey's Monumenta Britannica (1665-1693). On Ist Ed. OS map (1887). Planned by Colt Hoare 1810. Small excavation in the 19th century and 1957 by J.V.S. Megaw on section of innermost rampart. Landscape appraisal in 2002 recommended the removal of 1960s coniferous tree planting. RCHME survey as part of Salisbury Plain Project, ref. no. 888341.
