The monument comprises the remains of a burial cairn, probably dating to the Bronze Age (c.2300 BC - 800 BC) and situated in forestry to the NNE of the summit of Garn Wen, a hill on the SE side of Mynydd Trawsnant. The stone-built cairn is circular on plan and measures about 16.5m in diameter and up to 0.6m in height. Although it has been disturbed in the past - a small modern marker cairn has been created upon its summit and there are several small hollows - the majority of the base of the cairn appears to remain intact. The cairn displays no evidence of original 'bulk' and may represent the remains of a low platform cairn.

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 structural evidence and intact burial or ritual deposits. The possibility that the cairn is an example of a more unusual structural class of cairn, the platform cairn, further increases its importance, as does the topographic association with the contemporary burial cairn situated c. 650m to the SW (BR364).

The scheduled area comprises the remains described and an area around them within which related evidence may be expected to survive. It is circular and measures 30m in diameter.
