Round Cairn 315m S of Upper Wenallt is a prehistoric round cairn situated in Wales and protected as a scheduled monument by Cadw under reference MM046. The monument sits upon Lower Devonian bedrock, comprising interbedded sandstone and conglomerate formed during the Early Devonian period. This geological foundation of mixed sedimentary rocks would have presented Bronze Age builders with readily available stone for cairn construction.
The cairn occupies a landscape shaped by ancient geology, the undifferentiated Lower Devonian rocks underlying the site providing a solid base for the monument's construction. Round cairns of this type were typically raised as burial monuments during the Bronze Age, serving as enduring markers of prehistoric activity across the Welsh uplands and lower ground.
The monument's preservation under modern statutory protection ensures that this Bronze Age cairn remains a significant record of prehistoric land use in the region. Its location near Upper Wenallt anchors the site within its specific local landscape, distinguishing it amongst the numerous round cairns scattered across Wales' varied terrain.
