Summary

This fort is situated on a low hillock to the E of South Dumbuils, which falls away steeply along its S flank, but easily approached across gentle grassy slopes from the N. Oval on plan, it measures about 140m in length from E to W and expands to a maximum breadth of 70m towards the W end (0.65ha) within a rampart variously reduced to a stony scarp from the W round the S flank to the E, and a thick bank on the N; where best preserved on the NNW it is up to 9m in thickness by 0.8m in internal height. Additional protection around the more vulnerable N flank is provided by two outer ramparts, which can be traced from the NW round to the E; largely reduced to stony scarps, an evaluation trench excavated by Tessa Poller (2010) demonstrated that there was a medial ditch between them and that the inner of them, the middle rampart, may have mounted a timber palisade. The innermost rampart exhibited at least two periods of construction, the earlier comprising an earthen bank with a stone and timber revetment forming its leading face, and the later extensive reconstruction and thickening, incorporating stone work and possibly also timberwork. All three lines of defence are pierced by an entrance on the NW, from which a hollowed trackway can be traced to the rear of the inner wall, but there are at least three other gaps cut by later traffic into the interior, of which one mounting the slope obliquely on the E possible adapts an original entrance. Within the uneven interior there are traces of shallow quarrying, making it impossible to determine whether any of the visible features are of any antiquity, but one possible round-house platform can be seen on the SE, while a series of subrectangular features at the E end may be the result of later occupation.
