Summary

Large, multiphase and complex, multivallate, contour hillfort enclosing 11ha located on prominent Upper Chalk downland spur of Berwick Down above Wylye Valley 3km to SW, with access to river via dry valley S of Deptford Down. Circuit comprises three earthen ramparts with outer ditches, although outer ditch absent on NE as result of later downland drove way. Overall width of defences c. 20m. Outer rampart, up to 3.5m high above the 1.7m deep ditch, encroached upon by median rampart in places, suggesting that this and inner rampart were either constructed or enlarged later. In places berm at original ground surface level survives between middle and outer banks, and this and irregular quarry ditch along the inside of inner rampart, further evidence of alterations to original plan. Within hillfort interior is earlier enclosure of 5.2ha best preserved on W and SW. The marked 'causewayed' effect of ditch due Iron Age and Romano-British structures date into the feature, making use of shelter. On the NW ditch modified by track leading from entrance, and serving compounds and structures of later phase. Entrance into inner enclosure sited on W side and flanked by two low mounds which may be the remains of spoil heaps associated with Cunnington's excavations. Small enclosure outside ramparts on W probably late Romano-British stock enclosure. Quarry scoops behind inner rampart for most of circuit. Marked hollows in ditch bottoms, often reflected by 'dumps' on rampart crests suggest 'gang' working, as also do the straight rampart lengths. Of the seven breaches in the circuit, only those on N and E, and possibly on W, can be considered original, rest later and some possibly associated with Romano-British occupation or post medieval drove ways. Great intensity of occupation with over 130 probable structures surviving mainly as hollows up to 1m deep. Majority circular, 7m to 15m diameter, many being set within compounds or yards. On N and E, between earlier circuit and inner rampart, large compounds containing structures visible, with possible stone footings visible within many. Not all of these structures likely contemporary. Within a number of them indications of overlapping elements. Also pits, probably contemporary with the occupation, visible. In SE remains of Winterbourne Stoke sheep fair held biannually until 1916, when surrounding area commandeered by the army. Prominent sheep folds visible. Site excavated by Colt Hoare (1812) and Maud Cunnington (1933). On 1st Ed OS map (1887-8).

Investigation History

In Aubrey's Monumenta Britannica (1665-1693). On 1st Ed OS map (1887-8). Excavated 1800-10 by W.Cunnington Sen. and June 1932 by B.H. and M.E. Cunnington. Geophysical surveys by Geophysical Surveys of Bradford on behalf of RCHME in 1987.

Interior Features

Great intensity of occupation with over 130 probable structures surviving mainly as hollows up to 1m deep. Majority circular, 7m to 15m diameter, many being set within compounds or yards. On N and E, between earlier circuit and inner rampart, large compounds containing structures visible, with possible stone footings visible within many. Not all of these structures likely contemporary. Within a number of them indications of overlapping elements. Also pits, probably contemporary with the occupation, visible. Excavations have recovered Iron Age and Roman pottery, as well as inhumations in both graves and pits, and other human remains. Iron Age and Roman coins were also found. Roman material, including pottery, tiles, coins and burials from excavation and chance finds led to site's inclusion in Scott's gazetteer of Roman villas.

Entrances
