Gilfach-Fach Round Barrow is a prehistoric round barrow located in Wales and protected by Cadw under the reference CM115. The monument sits upon bedrock of Ashgill Rocks, an undifferentiated sequence of mudstone, siltstone and sandstone formed during the Ashgill period of the Ordovician. This geology provides a solid foundation of ancient sedimentary stone beneath the earthwork.
Round barrows were constructed throughout the Bronze Age as burial monuments, typically serving as interment places for individuals of status within their communities. The mound form allowed for repeated use over time, with successive deposits placed within or upon the structure. The Ashgill bedrock underlying the site would have been exposed or relatively near the surface when the barrow was constructed, offering stable ground for building.
The monument's preservation under Cadw protection reflects its archaeological significance as evidence of prehistoric burial practice and social organisation in Wales. The site contributes to our understanding of Bronze Age communities and their relationship with the landscape they inhabited, whilst the underlying Ordovician geology connects the monument to the deep geological history of the Welsh landscape.
