Overview

History & significance

Banc Round Barrow is a prehistoric round barrow located in Wales and protected by Cadw under reference CM120. The monument sits upon Ashgill bedrock composed of mudstone, siltstone and sandstone, geological strata that date to the Ashgill period and form the underlying foundation of the site. Like other round barrows of the Bronze Age, this earthwork would have served as a burial monument, constructed to commemorate and contain the remains of individuals of status within prehistoric communities.

The barrow's position on Ashgill geology places it within a landscape shaped by ancient sedimentary deposits laid down in a marine environment hundreds of millions of years before the monument's construction. The solid bedrock beneath would have presented both opportunities and constraints for the builders who raised the mound, influencing how they prepared the ground and structured the burial chamber. The monument survives as evidence of funerary practices and social organisation in prehistoric Wales.
