Bwlch y Ddeuwynt Round Cairn is a prehistoric mound burial monument situated in Wales. Constructed from stone gathered locally from the surrounding landscape, the cairn represents a form of funerary architecture built during the Bronze Age, when such monuments served as enduring markers of the dead and territorial claims across the upland regions of Wales. The monument's position reflects the Bronze Age settlement pattern of utilising elevated terrain.
The cairn was built directly upon Dinantian bedrock composed of limestone with subordinate sandstone and argillaceous deposits, geological strata typical of the Carboniferous period. This solid foundation of limestone would have provided workable stone for cairn construction, with the builders selecting suitable rubble and blocks from the immediate vicinity. The underlying geology has remained stable over millennia, preserving the monument's structural integrity.
Today, Bwlch y Ddeuwynt Round Cairn is protected and managed as an ancient monument by Cadw, the Welsh heritage organisation, under the reference BR352. This statutory protection acknowledges the cairn's significance as evidence of prehistoric burial practices and settlement in Wales, preserving it as a tangible link to Bronze Age communities whose lives and deaths shaped the Welsh landscape.
