Possible hillslope fort. Shown on OS 1:2500 1877 map as 'Gaer' when extant, sub-rectangular enclosure located on a slightly sloping plateau NE of St Mary Hill Down above the headwaters of the River Thaw to SE. Now only two sections of possible bank remain and could be result of quarrying activity. No sign of entrance. Shown on 1919 OS 1:2500 map as 'Roman Camp', possibly as result of rectangular shape. Quarry now disused and area under scrub and trees. Minimal investigations, undated.
