Summary

Large, multivallate, partial contour hillfort located on gentle SE-facing slope of Greensand promontory with commanding views over Nadder Valley. Topography has determined its triangular shape, with very steep surrounding slopes to NW, NE and SW and a gradual sloping narrow neck of level ground to the SE. The fort measures 500m NE to SW, by 480m NW-SE, and 17.5ha in extent overall, 9.7ha interior. On the promontory three ramparts, up to 10m high, with no trace of internal bank along the crest, with two intervening ditches, max. 1.5m deep, or as terraces. Across neck of promontory to SE, three massive banks and external ditches 75m wide in total; individual rampart crests up to 7.5m high above ditch bottoms. Outer rampart, in part, has a berm c. 3m wide, lying 1.4m below rampart crest, on inner side, suggested to provide access for defence on this, the most vulnerable flank, but this is pure conjecture. Breaks in outer rampart's crest may indicate unfinished state. Two original major entrances and possibly a further two simpler ones. Damaged entrance on E (at Red Barn), hollow way, 10m wide, 1m deep and now c. 50m winding passage, between middle and outer ramparts, which serve as hornwork, with additional outer bank and ditch. Middle and inner ramparts crossed through simple, staggered, gaps. W entrance and narrow covered way, 290m long max. 6m deep, crossing ramparts obliquely. Band below ramparts gives protection on lower side. Simple break in NE in middle possibly original entrance, upper rampart slightly inturned. To S another possible entrance, but badly affected by farm use. Narrow gap in the middle rampart at SW angle possibly original, but use uncertain as no visible breaks in upper or lower ramparts. Geophysics (Payne et al 2006) shows between 20 and 50 roundhouses, 10m-15m diameter, in the N half of the hillfort arranged in lines. Possibly a later phase represented by a series of irregularly shaped ditched enclosures. Pits scattered across the whole site. Finds of haematite pottery suggest an early Iron Age date, with possible multi phases of sustained occupation, and quarry hollows possibly characteristic of middle to late Iron Age phases of development. Possible long barrow on summit. General good condition although interior cultivated and ramparts heavily wooded. A fine and somewhat neglected hillfort at risk. On Ist Ed. OS map (1887).

Investigation History

In Aubrey's Monumenta Britannica (1665-1693). On Ist Ed. OS map (1887). Repair work undertaken by Wessex Archaeology in 1989 recorded partial section of inner ditch and part of outer bank. Partial section of S defences recorded by Wessex Archaeology after a landslip (Fielden 1991). Geophysical survey of interior as part of Wessex Hillforts Project 1997 (Payne et al 2006).

Interior Features

Entrances

Two original major entrances and possibly a further two simpler ones. Damaged entrance on E (at Red Barn), hollow way, 10m wide, 1m deep and now c 50m winding passage, between middle and outer ramparts, which serve as hornwork, with additional outer bank and ditch. Middle and inner ramparts crossed through simple, staggered, gaps. W entrance and narrow covered way, 290m long max. 6m deep, crossing ramparts obliquely. Band below ramparts gives protection on lower side. Simple break in NE in middle possibly original entrance, upper rampart slightly inturned. To S another possible entrance, but badly affected by farm use. Narrow gap in the middle rampart at SW angle possibly original, but use uncertain as no visible breaks in upper or lower ramparts.

Enclosing Works

On the promontory three ramparts, up to 10m high, with no trace of internal bank along the crest.Two intervening ditches, max 1.5m deep, or as terraces. Across neck of promontory to SE, three massive banks and external ditches 75m wide in total; individual rampart crests up to 7.5m high above ditch bottoms. Outer rampart, in part, has a berm c. 3m wide, lying 1.4m below rampart crest, on inner side, suggested to provide access for defence on this, the most vulnerable flank, but this is pure conjecture. Breaks in outer rampart's crest may indicate unfinished state.
