Garreg Wen round barrow is a prehistoric funerary monument situated in Wales and protected as a Scheduled Monument under Cadw reference CM318. Round barrows of this type were raised across Britain during the Bronze Age as burial mounds for individuals of status, typically containing inhumation or cremation remains within a central chamber or pit. The monument sits upon bedrock composed of Ashgill Rocks, an undifferentiated sequence of mudstone, siltstone and sandstone formed during the Ashgill period of the Ordovician, which provides the natural geological foundation across much of the surrounding landscape.
The barrow represents a significant marker of Bronze Age burial practice and social organisation. Such monuments were often constructed with stone and earth, creating distinctive circular mounds visible across the Welsh uplands and lowlands. The Ashgill bedrock, resistant to erosion, has helped preserve the monument's structural integrity over millennia.
Garreg Wen remains an important archaeological resource, its protected status reflecting its value in understanding prehistoric settlement patterns and funerary customs in Wales. The barrow contributes to the wider distribution of Bronze Age monuments across the region, providing evidence of how communities marked and maintained significant burial sites within their territorial landscape.
