Hirfaen Standing Stone is a prehistoric standing stone located in Wales, protected by Cadw as a scheduled monument under reference CM028. The stone rises from bedrock composed of Llandovery sandstone and conglomerate, interbedded geological formations that date to the Llandovery period. This substantial foundation of mixed sedimentary rock would have provided a stable base for the erection and long-term survival of the monument.
Standing stones of this type were typically erected during the Neolithic or Bronze Age, serving purposes that remain partly obscure but likely included territorial markers, burial monuments or points of ritual significance within the landscape. The Llandovery geology underlying the site, with its alternating layers of sandstone and conglomerate, is characteristic of the South Wales region and would have influenced both the stone's sourcing and its resistance to weathering over millennia.
The monument's preservation as a scheduled ancient monument reflects its importance as evidence of prehistoric settlement and social organisation in Wales. Its survival, embedded in the ancient bedrock of the Welsh landscape, continues to contribute to understanding of how early communities structured and marked their territory.
