Glog Fawr Platform Cairn is a prehistoric platform cairn located in Wales and protected by Cadw under reference RD201. Platform cairns are typically Neolithic or Early Bronze Age monuments consisting of a raised stone platform, often accompanied by a kerb or cist, and represent ritual or funerary practices of early farming communities. This example sits upon bedrock of Llandovery Rocks, undifferentiated strata of mudstone, siltstone and sandstone dating to the Llandovery period of the Ordovician era.
The monument's construction took advantage of the local geology, with builders selecting stone from the surrounding landscape to construct the platform. Such cairns often served as places of communal gathering or as burial monuments marking significant locations in the ritual and social landscape of prehistoric Wales.
The site's preservation and legal protection under Cadw reflect its importance as evidence of early human settlement and ceremonial practice in Wales. Platform cairns like Glog Fawr contribute to understanding the distribution and character of prehistoric monumental architecture across the Welsh landscape and the relationship between early communities and their environment.
