Cadw's description

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

The monument comprises the remains of a prominent round cairn, probably dating to the Bronze Age (c.2300 BC - 800 BC) and situated on the summit of Garn Wen, on the south flanks of the Gorllwyn. The burial cairn is circular on plan with a well-defined edge. It measures approximately 10m in diameter and up to 1.2m in height. Although it has been disturbed in the past - a large central hollow contains an OS triangulation pillar - the majority of the base of the cairn remains intact.

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 importance of the monument is further enhanced by the topographical association of the burial cairn with the many other cairns that can be found within the surrounding area.

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.
