                D-shaped mound, 28m by 22m and 2.5m high, resting on a river cliff above the Usk to the E, ditched elsewhere. Flat motte top a rhomboid with sides about 12m. (Coflein)
'a later fortified-site dependent on land tenure, possibly held for part of a knightâs fee. Such a site would have been needed to control settlement after the frontier of conquest had passed the area by. It is possible that the site may have once been a motte but the location and present size make this unlikely.' (Philips)
The monument comprises the remains of a motte and ditch, dating to the medieval period (c. 1066 -1540 AD). The motte is located on the W bank of the river Usk, and the ground drops sharp below the site to the river. The motte consists of a steep sided, flat topped mound, 3.5m high, and is D-shaped with the straight side being adjacent to the river. The top is 16m long (N/S) and 13m wide. On the N side there is a ditch 1.8m deep and 4m wide. (Scheduling Report)
