Summary

Univallate partial contour hillfort occupying a prominent position on N projecting spur of narrow part of Ebble-Nadder ridge. Ridge-top position strengthened by steep slopes falling to N and S. Interior area 4ha. On Andrews and Dury's Map of Wiltshire 1773. Access to site gained from W along main axis of ridge. Earthen rampart up to 3.6m high with external ditch to max. of 1.6m deep, well-preserved apart from some damage, constructed in series of straight or slightly curved sections suggesting possible gang working. At one point clear misalignment of two rampart sections. No internal quarry scoops suggest material for rampart from ditch. Small outwork, in poor condition, 60m long, lies against main rampart enclosing entrance on SE. Two linear earthworks, of two low banks and medial ditch, project from site. N linear, aligned roughly N-S, traced for c. 100m towards edge of escarpment. Much of its length N of enclosure obliterated by ploughing. S linear also aligned N-S, again been damaged by ploughing. Has total overall length of c. 155m and, unusually for cross-ridge dyke, course continues over edge of escarpment into bottom of steep combe that projects into the ridge from the S. These land boundary divisions possibly date from C. 500 BC. Eight narrow gaps, c. 2m-10m, gaps in bank, three having associated causeways across the ditch. At present that on SE thought original. Limited excavation by R.C.C. Clay 1923 found no evidence of occupation, but Iron Age pottery and spindle whorl or net sinker found outside. S cross dyke continues as buried feature beneath trackway which running along the ridge top. An Anglo Saxon charter refers to 'the ridgeway', suggesting the trackway used by, at least, early medieval period. During the medieval and post medieval periods, main route from Walton to Shaftesbury becoming turnpike by 18th century. Map of 1773 shows toll house immediately S of the road, visible today as series of earthworks of building platform with small enclosure to E. On Ist Ed. OS map (1887).
