Motte and bailey appears to have been constructed in part by utilising a natural promontory which was carved by deep ditches to form a defensive site. The motte survives to a height of 5.75m, with a diameter of 44m at the base and 17m at the top. This is separated from the bailey by a broad ditch 36m wide. The bailey has two entrances, one opposite the motte and the other at the south-west corner. Along the southern side the bailey is defended by a substantial ditch 34m wide and up to 8.5m deep. Rounded projections at the corners of the bailey and along the southern side may have been associated with towers. Wat's Dyke, which runs along the western side of the site, has been used as an additional defence forming a ditch up to 18m wide.Little is known of the history of the site, although it may be 'Wrislesham', referred to in the sheriff's annual accounts of 1161.
