Rhiwiau Round Barrow is a prehistoric funerary monument located in Wales, comprising an earthen mound constructed during the Bronze Age. The barrow sits upon bedrock of Arenig rocks, comprising mudstone, siltstone and sandstone formed during the Arenigian geological period, which provides a firm foundation across the upland landscape. This underlying geology is typical of the region and would have been familiar to the prehistoric communities who selected this location for burial.
Round barrows of this type served as communal or high-status burial places, often marking prominent positions in the Bronze Age landscape. The monument's earthwork construction represents a significant investment of labour by the local population, suggesting the person or people commemorated held considerable importance within their society. Such barrows frequently contained cremated or inhumed remains, along with grave goods reflecting the status and beliefs of the period.
The barrow is protected as a scheduled ancient monument by Cadw, the Welsh historic monuments service, recorded under reference PE344. This designation recognises its archaeological significance and ensures the site is preserved for future study and public understanding of Wales's prehistoric heritage.
