The monument comprises the remains a burial cairn, probably dating to the Bronze Age (c. 2300 - 800 BC). The barrow is circular in plan and has a rounded profile. It stands c.2.2m high, with a diameter of c.20-22m.

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. It takes the form of a circle enclosing the barrow, with a diameter of c.25m. The circle is flattened where the perimeter of the scheduled area follows the boundary fence in the north and west.
