The monument comprises a well-preserved and intact example of a ring cairn, which probably dates to the Early Bronze Age (c. 2000-1500 BC). It comprises a circular bank of turfed-over stones some 10m in diameter, 2.0m wide and 0.5m high. Along its north-western edge, the heap of stones making up the body of the cairn is held in place by an internal kerb of six upright slabs of stone about 0.4m in height. The site is partially obscured by a recent clearance cairn. The monument is associated with the Fonllech Hir prehistoric trackway and the Moel Goedog ring cairns.
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, including intact burial remains and preserved prehistoric ground surfaces below the monument, together with environmental and structural evidence. Ring cairns may be part of a larger cluster of monuments and their importance can be 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.
