Summary

Large, univallate, partial contour hillfort, oval in plan, sited on S side of prominent downland ridge of Haydown Hill, with commanding views in all directions. Measures 430m by 330m, with interior area 10.5ha. Massive rampart, ditch and counterscarp, with interior quarry ditch on all S side. Fine inturned E entrance with four other indeterminate entrances. Surface evidence of hollows in interior, 1m to 4m in diameter and up to 0.5m deep, suggesting possible pits and or hut platforms as mapped by Ordnance Survey, but the geophysical survey showed little evidence apart from a few pits (Payne et al 2006). Fieldwork by Nichol 2001 found burnt flint, water worn pebble (perhaps slingstone), sherd of pottery of fine sandy fabric. Iron Age sherds found by Grinsell and Meyrick. Notable Celtic fields in vicinity and well-developed block of prehistoric fields, best on E and S slopes of hill, with lynchets seemingly overlain by hillfort counterscarp, so possibly pre-dating it. Site ploughed in past, but now permanent pasture. N ramparts wooded. On Ist Ed. OS map (1880).

Interior Features

Quarry hollows along S side interior. Surface evidence of hollows in interior, 1m to 4m in diameter and up to 0.5m deep, possible pits and or hut platforms,as mapped by Ordnance Survey, but the geophysical survey showed little evidence apart from a few pits. Iron Age sherds, burnt flint, water-worn pebble (perhaps slingstone), sherd of pottery of fine sandy fabric.
