Carn Owen, Cerrig yr Hafan is a prehistoric round cairn located in Wales and protected as a scheduled ancient monument under Cadw reference CD045. The cairn sits upon bedrock of Ashgill age, composed of mudstone, siltstone and sandstone that formed during the Ordovician period. This geological foundation is typical of upland areas in Wales where such monuments are commonly found.
Round cairns of this type date to the Bronze Age and were constructed as burial monuments, built from locally gathered stone piled into distinctive circular mounds. The choice of this particular location reflects the Bronze Age practice of positioning such monuments in prominent positions across the landscape, often on high ground or ridges where they would be visible across considerable distances.
The preservation of Carn Owen, Cerrig yr Hafan as a scheduled monument ensures protection of its archaeological integrity. The site's survival allows for continued study of Bronze Age burial practices and settlement patterns in Welsh upland regions, whilst the underlying Ashgill strata provide context for understanding the local geology and environment in which these prehistoric communities lived and chose to memorialise their dead.
