A low-lying motte on an alluvial terrace near W bank of Taff is a flat-topped mound 30m in diameter at base, 13m at top, and 3.8m high, surrounded by a flat-bottomed ditch 7m wide and averaging 0.5m deep. An adjoining bailey of rectilinear form is vaguely outlined by scarps to the E of the motte. Some damage has been caused to the bailey by recent nearby developments. (Coflein)

A castle mound 38m in diameter and 5.5m high, in good condition, the top being flat and tree-covered. The surrounding ditch is 6.5m wide and water-filled. There are no traces of a bailey, and no signs of masonry. (Glamorgan-Gwent Archaeological Trust HER)
