Summary

Located on a prominent hilltop rising out of the Thames Valley NW of Chertsey. Possibly univallate enclosing 4.7ha although the ramparts are hard to follow due to tree cover and destruction by quarrying, a reservoir and trackways that cut across the hilltop. Roughly oval in plan, aligned NW-SE, univallate with an outer ditch and counterscarp bank, the earthworks are best preserved along the W side where the broad rampart, standing to a height of c.1.0m, is fronted by a ditch, c.1.5m-3.0m wide and up to c.0.5m deep, partially interrupted by a footpath. Beyond is a broad counterscarp bank less than 0.5m high. Within the fort the main rampart is only c.0.1m-0.3m above the interior. Damage to the S caused by the Dingle, a gravel quarry. There are traces of a second, outer rampart flanking the SE area of the circuit. Small excavations in 1990 showed the rampart to the NW to be of two phases, material from the ditch forming a dump rampart which was then increased in height with the ditch being re-cut. A small trench in the interior revealed domestic structures, pits, postholes, beam slots, together with early and middle Iron Age pottery suggested to be of three phases (Bird et. al. 1991). No evidence for an entrance. In the NE of the enclosure are the ruined remains of the 14th century St. Ann's chapel, possibly once associated with nearby Chertsey Abbey. Late 18th century, and later, landscaping. A reservoir and associated buildings in the interior. A Late Bronze Age spearhead found in topsoil. On OS 1:25,000 map (1937-61), RCHME survey (McOmish and Field 1994).
