The monument comprises the remains of a ring cairn of earth and stone, which probably date to the Bronze Age (c. 2300 - 800 BC), which is 540m southwest of Llyn Tarw and measures 19m along its north south axis and has a width of 18m. The ring is defined by a bank that varies between 0.3m and 0.6m in height and has a maximum width of 2.5m. The bank is composed of stones, some of which are quite large; there is no sign of an external ditch.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. The feature is an important relic of a prehistoric funerary and ritual landscape and retains significant archaeological potential. There is a strong probability of the presence of both intact ritual and burial deposits, together with environmental and structural evidence. Ring 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.
