Contour hillfort located on prominent, rounded NE-SW ridge overlooking the steep valley of Afon Clywedog from N commanding confluence of Clywedog and River Severn. Precipitous slopes to S and W. Only found by RCAHMW aerial survey 2003. Interior measures c. 70m N-S by 50m, with area c. 0.35ha. Defined by three parallel banks c. 40m long and to 2.5m high occupying slight hollow, which measure up to 40m in length and stand a maximum 2.5m high, each with lesser outer ditch. Two further lines of rampart c. 35m long define E, to S of main entrance at NE corner of fort. Precipitous slopes provide defence on S and W. Rocky upland pasture. Minimal investigations, undated.
