Two Round Barrows 300m North of Tair Onnen is a prehistoric round barrow situated in Wales on bedrock of the Lias Group, comprising mudstone, siltstone, limestone and sandstone laid down during the Aalenian period. The monument consists of two earthen mounds raised over burials, a form of funerary monument characteristic of Bronze Age communities in Britain and Ireland. The underlying geology of this area, with its mixed lithologies, would have provided varied stone and soil suitable for constructing and maintaining such earthworks.
The barrows occupy a landscape shaped by their geological foundation, where Aalenian deposits create undulating terrain typical of Liassic regions. Such locations were commonly selected for burial mounds throughout prehistoric Wales, offering visibility across the surrounding countryside whilst being situated on moderately elevated ground. The monument survives as a testament to Bronze Age funerary practices and settlement patterns.
The site is protected by Cadw, the Welsh Historic Monuments service, under reference GM390, ensuring the preservation of this important archaeological feature. Round barrows of this type remain significant for understanding prehistoric social structures, burial rites and the relationships between communities and their landscape across Wales.
