# Round Barrow SW of Pen-Rhiwlas
Round Barrow SW of Pen-Rhiwlas is a prehistoric funerary monument constructed during the Bronze Age, likely between 2200 and 1500 BCE. The barrow comprises an earthen mound raised over a burial or cremation, typical of burial practices across Wales during this period. Such monuments served as lasting memorials to the dead and marked significant territorial or social positions within Bronze Age communities.
The barrow sits on bedrock composed of Llandovery rocks—undifferentiated mudstone, siltstone and sandstone deposits formed during the Silurian period, approximately 440 million years ago. This geology would have influenced the construction and preservation of the monument; the softer sedimentary bedrock contrasts with harder stone used elsewhere in Wales, potentially affecting how the barrow's earthwork settled and eroded over millennia.
The monument is protected by Cadw, the Welsh Historic Monuments service, under scheduled reference CD118. This statutory protection recognises its archaeological significance as an important survival of Bronze Age mortuary practice and landscape use in Wales. The barrow contributes to understanding settlement patterns, land division and burial traditions in prehistoric Welsh communities.
