Cerrig Pryfaid Stone Circle is a prehistoric stone circle located in Wales and protected by Cadw as a scheduled ancient monument under reference CN130. The site stands upon bedrock composed of felsic tuff, an Ordovician extrusive rock formed over 440 million years ago during the early Paleozoic era. This volcanic geology is characteristic of the Welsh uplands, where such rocks underlie many Bronze Age and late Neolithic ritual monuments.
Stone circles in Wales typically date to the Bronze Age, though some may have earlier origins. These monuments served ceremonial, calendrical or burial functions within their communities, often positioned on elevated terrain where the bedrock would have been exposed or easily worked. The choice of this Ordovician volcanic foundation suggests the builders selected a naturally prominent location, possibly exploiting existing rock outcrops for the circle's construction.
The felsic tuff bedrock would have provided suitable stone for monument building, though the specific materials of the circle's uprights reflect the local geological resources available to its constructors. Such stone circles remain important markers of prehistoric land use and ritual practice across Wales, testament to the enduring relationship between ancient peoples and their landscape.
