Cadw's description

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

The monument comprises the remains of two burial cairns, dating to the Early Bronze Age (c. 2000-1500 BC). Both monuments are made up of turf-covered heaps of boulders. Cairn I is oval and measures some 10m by 8m and stands 0.5m high. Cairn II is round and measures 8m in diameter and 0.5m high. They are closely associated with the Garreg Las hengiform monument and cross-dyke.

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.
