The most impressive of the group of seven cairns. A low circular mound 13.75 m in diameter, divided into concentric circles by (i) a c. 11.5 m-diameter ring of slate slabs set on edge and standing up to 0.3 m high (on the E side of the mound the slates are in a shallow depression); (ii) a ring of large flat stones c. 8.2 m in diameter; (iii) on the NW, a further part circle of large stones. Towards the centre of the cairn is a cist 1.8 m by 1.2 m with its long axis roughly N-S. The E side is formed by a single large slab 1.5 m long. The N side appears to be built up of smaller stones. The other two sides are not clearly definable. Immediately to the W of the cist is the capstone, c. 3.05 m by 1.5 m by 0.6 m. The main body of the cairn was made up of small stone.

The monument is of national importance for its potential to enhance our knowledge of prehistoric funerary practises. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
