The monument comprises the remains of a burial cairn, probably dating to the Bronze Age (c. 2300 - 800 BC).

It is the southernmost and best preserved cairn on the summit of Pen Plynlimon-Fawr. The cairn is 15 metres in diameter and about 3 metres in height, including a modern cairn on the top.

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 be 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.
