The monument comprises the remains of a burial cairn, which probably dates to the Bronze Age (c. 2300 - 800 BC). It is situated on the south-facing slopes of Mynydd y Garth. The stone-built cairn is roughly circular in shape on plan and measures 12m in diameter and up to 1m in height. Kerbstones are visible on the north and north-west sides. The centre of the cairn mound has been disturbed, but the monument survives substantially intact.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. The well-preserved monument is an important relic of a prehistoric funerary and ritual landscape. It retains significant archaeological potential, with a strong probability of the presence of both intact burial or ritual deposits, together with environmental and structural evidence, including a buried prehistoric land surface.

The area scheduled comprises the remains described and an area around within which related evidence may be expected to survive.
