Cadw's description

The following provides a general description of the Scheduled Monument.

The monument comprises the remains of a stone-built round cairn, probably dating to the Bronze Age (c. 2300 - 800 BC). It is located on top of a local summit, Cerrig Blaencletwr-fawr, a prominent rock outcrop on Esgair Foel-ddu. The cairn is sub-circular in shape on plan and measures c. 11m NE-SW by 9m transversely. It measures c. 0.9m in height. There is a modern shelter measuring 3.5m in diameter and 1m in height set into its centre.

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 burial or ritual deposits, together with environmental and structural evidence.

The scheduled area comprises the remains described and an area around within which related evidence may be expected to survive. The scheduled area is circular in shape on plan and measures 18m in diameter.
