Bwlch yr Adwy Round Barrow is a prehistoric round barrow situated in Wales. Round barrows of this type were constructed during the Bronze Age as burial monuments, typically containing single or multiple inhumations or cremations accompanied by grave goods. The barrow at Bwlch yr Adwy would originally have formed a conspicuous earthen mound in the landscape, serving both as a burial chamber and a territorial marker for the communities who built it.
The monument sits upon bedrock of Llandovery age, composed of mudstone, siltstone and sandstone deposits laid down during the early Palaeozoic era. These materials would have shaped the construction technique and structural integrity of the barrow, determining how the soil and stone were worked into the characteristic mound form. The geological character of the site influences its survival and archaeological significance.
The barrow is now protected by Cadw, the Welsh heritage organisation, under the reference CD251. This statutory protection recognises the monument's archaeological importance as evidence of Bronze Age burial practice and settlement patterns in Wales. The designation ensures that the site is preserved for future study and public access.
