Summary

Small, univallate, hillslope fort located on steep SE-facing slopes opposite to The Fron fort at Newcastle on Clun, and at the confluence of Folly Brook and the River Clun in an area of small hillforts. Overlooked from the W. The site is nearly circular in plan, measuring 100m by 108m, with internal area c. 0.35ha. The bank reaches up to 1m in height and 10m on the W, where it is best preserved, with an outer ditch 6m wide and 0.5m deep. Elsewhere it is reduced to an outward facing scarp with no ditch visible, although this is now probably a buried feature. Both the bank and the ditch have been subject to ploughing and to the E the former has been mostly levelled. Building platforms have been recorded in the interior and the site has been well managed for decades. Ridge and furrow in the pasture interior. Undated. On 1st Ed OS map (1885-1900).
