 It is defined by an earthen rampart up to in height and an external ditch, up to a maximum of in depth.A gap in the southeastern side of the rampart, and a corresponding causeway across the ditch, is thought to be the original entrance and is associated with a small 'D' shaped embanked enclosure, which is apparently visible on aerial photographs.Although the enclosure has subsequently been degraded by ploughing, it is still apparent as a series of low earthworks.
