A cist constructed of five blocks originally below a low mound with a diameter of 9m. The chamber 1.8m x 7.6m x 0.9m contained the remains of at least twenty individuals though none were articulated. It is believed that the chamber was used to deposit the bones of the dead after the flesh had rotted away (known as scarnification). Pottery and flint scrapers were also found during the excavation in 1922.
