• This astonishing portal dolmen, one of the largest in Ireland, measures 4.5m by 3.3m and was constructed before 2000 BC.
• Because of the distortion caused by the slipped capstone the chamber dimensions are difficult to judge, but the original space was probably polygonal and about 2m in diameter. Excavated in 1954, the chamber contained considerable amounts of cremated bone, and a small porcellanite axe, or adze, from the Thievebulliagh axe factory in County Antrim. Other finds outside the chamber included a flint flake and a carinated chert core-scraper.
