Cadw's description

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

The monument comprises the remains of three burial cairns, probably dating to the Bronze Age (c. 2300 - 800 BC). They are located close together on moorland.

Cairn A - The cairn lies on a south facing slope. It has a diameter of 7m and is c.1m high, except on the north side where it backs onto the natural slope. It is covered with bracken and turf, with small stones showing on the surface. In the middle is a deep hollow 1.5m x 2m and c. 1m deep, with a large conglomerate stone at its west end.

Cairn B - The cairn, 13m in diameter, c.1.5m high, consists of a turf rim, 0.3m high, irregular and of varying width, with a very irregular interior of stones and turf, with some large boulders. In the centre is a disturbance hollow with rubbish in it.

Cairn C - The cairn is 20m in diameter, 1.5m high, the highest part being at the west end. It consists of large stones with a hollow in the centre, c.2 x 2m, 0.5m deep. Around it is a grass bank, 0.5m high.

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.
