The motte measures c10.5m in diameter across the top and 32m in diameter across the base and is c5m high. It is surrounded by a ditch c6m broad. The east side of the mound is somewhat hollowed away. There are traces possible traces of a dam to the east, which could have ponded back an area of c.160m N-S by 100m. A bailey enclosure may have lain to the south, between the motte and a mere.
