Summary

Commanding and mainly bivallate contour hillfort located on end of slight spur on the ridge of Wears Hill on Upper Greensand sandstones overlooking Chesil Beach and Portland. Developed from an earlier univallate hillfort. Moderate to strong surrounding slopes to N, E and W, strong generally to S, but less on SE. Commands extensive views and access along South Dorset Ridgeway. Triangular shape enclosing c. 4ha. Unusual shape governed by topography. Two ramparts, following the contours, with medial ditch. Probably phased construction. SE end strengthened by two additional banks with outer ditches, inner possibly original end of univallate enclosure, later superceded by new bank, obliterating ditch and with two new ditches. At SW, SE and, to lesser extent, N internal corners addition of internal mounds/enlargement of ramparts - unclear as to use. SW one suggested by RCHME (1952) as Roman signal post, but small excavation at the SW end 1974-75 found this not to be the case (Beavis 1974; 1976). Formerly complex, possibly inturned, entrance through banks on E approached by clear sloping passage. Probably disturbed by road and access into site. Number of circular hollows/platforms (at least ten) in interior thought to be roundhouse sites. Possible barrow shows as mound. Pasture and scrub/bracken interior, scrub on banks. Fair condition. South West Coast Path along S border of site. On 1st Ed. OS map (1889). Undated.

Hillfort Type

Commanding and mainly bivallate contour hillfort located on end of slight spur on the ridge of Wears Hill on Upper Greensand sandstones overlooking Chesil Beach and Portland. Developed from an earlier univallate hillfort. Moderate to strong surrounding slopes to N, E and W, strong generally to S, but less on SE. Commands extensive views and access along South Dorset Ridgeway. Plateau area c. 20m lower than hillfort around N and S sides, which fort overlooks. Slightly sloping to N. Unusual shape governed by topography.
