Summary

Univallate hillslope fort sited on slight SE-facing downland spur slope above the River Wylye Valley. Smallest hillfort in MOD Salisbury Plain Training Area, enclosing 1.75ha. Oval in plan, fort built on relatively level/slighltly sloping ground and akin to Casterley Camp (Atlas No 0389), lacking general topographical advantage. With substantial bank, deep and wide ditch and counterscarp (lower on E), as unusual sub-rectangular shape with concave sides and marked protuberance to the NW, result of construction on earlier field system. Best when viewed from S. Located in area of great archaeological interest on Knook Down West (see Bowden 2005, Fig 3.27), it was planned by Colt Hoare 1812 and Flinders Petrie in 1877. Evidence of Celtic fields, Romano-British settlement (to N), bowl barrow and S-shaped lynchet, all in vicinity of fort. Simple entrance on the SE side and a modern break on the W. Has been described as defensive cattle-pen associated with nearby Romano-British settlement, but clearly hillfort. Slight ridge and furrow in interior. Heavy cattle grazing damage. Undated. On Ist Ed. OS map (1887).
