A large motte and bailey earthwork castle, set on a commanding position above the village. The motte is a steep-sided, flat-topped mound, oval in plan, 50m by 38m overall and 6.6m high. The summit is about 24m by 16m. The bailey, on the south-west side of the motte, was at least 56m by 40m. Its southern side is obscured by the modern road. Both motte and bailey were ditched and counterscarped. Similar earthwork castles in Wales date to the twelfth century, or the earlier part of the thirteenth century. The absence of any visible stonework suggests that the castle did not retain its importance beyond that period. (Coflein)

This is the best preserved motte and bailey castle in Breconshire. An oval tree-clad motte 6m high occupied the east half of a bailey platform 115m long by 45m wide. Circumstantial evidence suggests the castle was built by Bernard de Newmarch c1095 and fell to a Welsh attack sometime between 1121 and 1136. It was probably then abandoned although possibly rebuilt in the 1150s by Walter Clifford. (Salter)
