Cadw's description

The following provides a general description of the Scheduled Ancient Monument.

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 situated in open grassland with some stone visible on its surface. The cairn has a diameter of 15.5m with a dished interior; it stands 0.6m above the surrounding field.

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.
