The following provides a general description of the Scheduled Monument. The monument comprises the remains of a burial chamber, probably dating to the Neolithic (c. 4,400 - 2,900 BC). It is located in an enclosed field of pasture on a gentle SE-facing slope at the edge of a limestone terrace. The construction is unusual as the capstone appears to have been levered from the bedrock and propped up by low stones at its outer edge. The capstone has broken into three pieces and rests above a partially collapsed chamber. The capstone measures c. 4.6m long, up to 2.8m wide and 0.8m thick. It is aligned E-W. The central section stands to a height of 1.4m. A slight rise in the ground around the burial chamber represents the remains of the covering mound. It is circular and measures c. 14m in diameter. Part of the chamber was excavated in 1909. The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. The burial chamber is an important relic of a prehistoric funerary and ritual landscape. It retains significant archaeological potential and there is a strong probability of the presence of burial, ritual or structural evidence. The monument's importance is further enhanced by its unusual construction and its proximity to Benllech Megalith (SAM number AN094), which is located c. 850m NW. The scheduled area comprises the remains described and an area around them within which related evidence may be expected to survive. It is circular and measures 25m in diameter.
