Defensive earthwork. The site consists of a steep sided, flat topped, irregular shaped, artificial knoll. It is cut away from the high ground to the north-east by a deep ditch and trench and protected on the south-west by boggy ground and a watercourse. It has variously been referred to as a Tumulus, a fort called The Castle, a Norman motte - the lower court or bailey of which has supposedly been obliterated - and an inland pre-Viking fort. Another suggestion is that the site held the residence of an important landowner and was of a defensive character.


It is 10-11m in diameter and stands 2.7m above the ground to the east and 5-6m above the stream to the west. It is grass and gorse bush-covered so no stonework can be seen. A ditch, averaging 6m wide and 2.5m deep, survives to the south and south-east and possibly continued around its east and north sides but has now been filled in by adjacent cultivation soil. It is unlikely that a ditch would have been required on the west side where the natural watercourse makes it unnecessary. Partial excavation of the interior revealed half the plan of a circular timber house, about 10.5m in diameter. This would have occupied most of the summit of the mound.
