Cadw's description

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

The monument comprises the remains of a platform cairn, probably dating to the Bronze Age (c.2300 BC - 800 BC) and situated in open moorland on summit of Moel Eiddew at the S end of Mynydd y Cemmaes. The grass-covered stone-built platform cairn is circular on plan and measures about 14m in diameter over a well-defined level platform up to 0.6m in height. Although there are several small hollows visible within the platform - and a concrete triangulation pillar has been built upon the NW side - the monument appears to be undisturbed. The platform cairn commands spectacular views over the surrounding landscape.

Platform cairns were erected both singly or as part of larger cemeteries. Excavated examples have shown these monuments to be essentially ceremonial - although with a consistent link with the burial of the dead where some cremation burials have been revealed. Rituals involving the burning and deposition of charcoal, perhaps symbolic of the funeral pyre, would seem to have been important.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. The well-preserved and unusual 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 and environmental and structural evidence.

The area scheduled comprises the remains described and an area around them within which related evidence may be expected to survive. It is circular and measures 28m in diameter.
