A low-lying motte located on an alluvial terrace near the west bank of the River 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 east of the motte. Some damage has been caused to the bailey by recent nearby building and access developments.
Dense vegetation has also made difficult the recognition of slighter features.
Analysis by Bryn Gethin in 2010 of aerial photography shows that the bailey measures approx. 60m by 40m.
