The monument comprises the remains of two earthen built round barrows, which probably date to the Bronze Age (c. 2300 - 800 BC). The barrows are circular in shape on plan and have a rounded profile. Cairn I measures 10m in diameter with two peripherally located stone lined cists, and perhaps also a central cist although this is less clearly defined. Cairn II is slightly smaller in size and has only one cist.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. The features are an important relic of a prehistoric funerary and ritual landscape and retain significant archaeological potential. There is a strong probability of the presence of both intact ritual and burial deposits, together with environmental and structural evidence. Barrows 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. It is a recangle and measures 30m x 70m.
