Tyfos Stone Circle is a prehistoric stone circle located in Wales and protected as a scheduled monument by Cadw under reference ME024. Stone circles of this type were erected during the Bronze Age, typically serving ritual, ceremonial or astronomical functions within their communities. The monument stands upon bedrock of Ashgill rocks, an undifferentiated sequence of mudstone, siltstone and sandstone dating to the Ashgill period of the Ordovician era, which creates a foundation of weathered sedimentary geology characteristic of upland Welsh terrain.
The circle's position on this ancient bedrock reflects the Bronze Age builders' practical knowledge of their landscape. The Ashgill rocks would have been exposed or shallow across much of the surrounding terrain, offering both stone sources and stable ground for construction. The specific combination of rock types at this location—mudstone interspersed with harder siltstone and sandstone—would have influenced which stones were selected and how they weathered over millennia.
Today, Tyfos Stone Circle remains a tangible link to prehistoric religious and social practices in Wales. Its Cadw protection ensures the monument's preservation for future study and public understanding of Bronze Age ceremonial landscapes and the communities that shaped the Welsh countryside.
