Aberyscir Round Cairn is a prehistoric round cairn located in Wales and protected by Cadw under reference BR139. The monument sits upon bedrock of Lower Devonian rocks, a foundation of mudstone, siltstone and sandstone deposited during the Early Devonian period. This underlying geology would have shaped both the landscape and the availability of stone for the cairn's construction.
Round cairns of this type typically date to the Bronze Age, serving as burial monuments for prominent members of prehistoric communities. Built from stones gathered from the surrounding terrain, they often contained cremated remains within central burial deposits or chambers. The specific geology of Aberyscir's location—the mixed sedimentary rocks of the Lower Devonian—would have influenced which stones were selected and how the cairn was engineered.
As a Cadw-protected monument, Aberyscir Round Cairn remains an important record of prehistoric funerary practice in Wales. The cairn's survival provides evidence of Bronze Age settlement patterns and social organisation in this region, whilst its position on the Lower Devonian bedrock demonstrates how ancient builders worked within the constraints and resources offered by their immediate geological setting.
