Bryn-Poeth-Uchaf is a prehistoric ring cairn situated in Wales, protected as a scheduled ancient monument by Cadw under reference CM345. The monument consists of a circular arrangement of stones typical of Bronze Age burial practices, constructed on bedrock composed of Ashgill rocks—a sequence of mudstone, siltstone and sandstone formed during the Ashgill geological period. This solid foundation of fine-grained sedimentary geology provided a stable base for the cairn's construction.
Ring cairns represent a distinctive funerary tradition, with the characteristic doughnut-shaped plan of stones surrounding a central open space or burial area. The Ashgill bedrock beneath Bryn-Poeth-Uchaf would have been suitable for quarrying the stone used in the monument's construction, making this site practically sited as well as spiritually significant.
The monument's survival to the present day reflects both the durability of stone construction and the protection afforded by its remote Welsh location. As a scheduled monument, Bryn-Poeth-Uchaf remains an important archaeological record of Bronze Age burial customs and the relationship between prehistoric communities and their landscape.
