Cerrig Duon Stone Circle is a prehistoric stone circle located in Wales and protected by Cadw under reference BR071. The monument stands upon Lower Devonian bedrock, comprising interbedded sandstone and conglomerate deposits laid down during the Early Devonian period. This geological foundation has shaped the character of the landscape surrounding the site for over 400 million years.
Stone circles represent one of the most significant monument types of British prehistory, typically constructed during the Late Neolithic and Bronze Age periods. These ritual and ceremonial structures served diverse purposes within their communities, from gatherings and celebrations to astronomical observations and burial practices. The choice of this particular location, with its solid Devonian geology, would have provided a stable foundation for the upright stones.
The monument's survival to the present day reflects both the durability of its stone construction and the protective status it has received. Cadw's stewardship ensures that Cerrig Duon remains accessible to the public whilst its archaeological significance is preserved for future generations. The site contributes to our understanding of prehistoric Welsh communities and their monumental practices.
