Waun Coli round cairn is a prehistoric circular burial monument sited on the moorlands of Wales. Built from stone gathered across terrain underlain by Ashgill rocks—a sequence of mudstones, siltstones and sandstones deposited during the Ashgill period of the Ordovician—the cairn would have served as a tomb for one or more individuals during the Bronze Age or earlier prehistory. Such monuments typically accumulated through successive episodes of use and ritual activity, their stone mounds remaining visible across the Welsh landscape as testament to ancient burial practices and the labour invested in commemoration of the dead.
The cairn's location reflects deliberate choice of elevated, open ground characteristic of prehistoric funerary monuments in upland Wales. The underlying geology, weathered to broken stone and moorland soil, provided readily available building material. The monument's survival into the modern era, protected by Cadw under reference BR365, preserves evidence of how prehistoric communities marked and memorialised significant individuals within their territories. Its form and placement contribute to our understanding of settlement patterns, social organisation and ritual life in prehistoric Wales.
