This large Bronze Age cairn stands on a small hill east of Westhills Camp. It is built of stone and earth. On top of the cairn is a hollow with a tree stump growing in it. The hollow is the remains of an unrecorded excavation in the 19th century. Nearby, three stones bearing at least thirty cup marks were recorded in the early 20th century and were probably of Neolithic date. Their purpose is unknown, though they may have had a religious purpose. The cairn is a Scheduled Monument protected by law.
