Summary

Virtually destroyed, multivallate, contour hillfort located on NE-SW ridge top of Coed Mawr S of Cefn Carnedd hillfort (Atlas No 1448), directly above the River Severn Valley to E and S at Llandinam. Precipitous to very steep surrounding slopes to E, steep to W and N, moderate along ridge to SW. Measures 110m NE-SW by 70m overall with total area 0.8ha. Last hillfort along the Severn and Wye valley before the Pumlumon massif. Up to five ramparts mentioned by Pennant (1778), and in evidence in 1868. Isolated fragment recorded by Spurgeon (1972) near Y Gaer farm. Now defined by scarps 1.3 to 2m high, except on S where traces of bank, ditch and counterscarp. Probable entrance at SE corner. Under improved pasture. On 1st Ed. OS map (1886). Minimal investigations, undated.
