Bongam Bank Round Barrows is a prehistoric round barrow situated on igneous bedrock of Silurian age in Wales. The underlying mafic igneous rock, part of an unnamed intrusion dating to the Ordovician to Silurian period, has shaped the solid geology upon which this Bronze Age monument rests. Round barrows of this type typically served as burial mounds for high-status individuals, constructed from earth and stone gathered from the surrounding landscape and heaped over grave pits or chambers.
The monument is protected by Cadw, the Welsh historic monuments service, under reference RD007. This designation ensures its preservation as an important archaeological resource. The barrow's position on this particular geological substrate reflects the choices made by its Bronze Age builders, who selected this location despite the challenging bedrock conditions. Such round barrow cemeteries are characteristic features of Bronze Age Wales, representing enduring expressions of burial practice and social hierarchy across several centuries.
