The monument comprises the remains 2 burial cairns, probably dating to the Bronze Age (c. 2300 - 800 BC). The largest cairn measures 16.8m in diameter by 1.8m high and has a large central hollow measuring 1.2m deep. This hollow (probably the result of robbing) reveals that the mound is made up of stones and earth. To the north-east of the largest cairn lies a smaller example measuring 7.9m in diameter and 0.9m high. A slight central hollow is surrounded by a stony rim. Both are grass covered and circular in plan.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. The monument is an important relic of a prehistoric funerary and ritual landscape and retains significant archaeological potential, with a strong probability of the presence of both intact burial or ritual deposits, together with environmental and structural evidence. Cairns may be part of a larger cluster of monuments and their importance can further enhanced by their group value.

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