Bryn-Poeth-Uchaf is a prehistoric ring cairn located in Wales and protected by Cadw under reference CM344. Ring cairns are Bronze Age monuments comprising a circular bank of stones surrounding a central space, typically built as burial or ceremonial structures. This example sits upon bedrock formed from Ashgill rocks, a geological formation of mudstone, siltstone and sandstone dating to the Ordovician period. The underlying geology would have influenced the cairn's construction, as builders worked with locally available stone resources from these consolidated sedimentary deposits.
The monument's position in the Welsh landscape places it within a tradition of upland burial practice characteristic of Bronze Age communities in Britain. Ring cairns of this type often occupy elevated locations where suitable stone could be readily gathered. The Ashgill bedrock composition—a mix of fine-grained sediments—would have provided workable material for cairn construction, though the precise dating and funerary history of this particular monument remain subjects for archaeological study.
