Cwm Irfon Standing Stone is a prehistoric standing stone located in Wales and protected by Cadw under reference BR264. The monument rises from bedrock composed of Ashgill rocks—mudstone, siltstone and sandstone deposited during the Ashgill epoch of the Ordovician period. This geological foundation, typical of the upland regions of mid-Wales, provided the source stone for such monuments and shaped the landscape in which Bronze Age communities erected their markers.
Standing stones of this type were raised across Britain during the Bronze Age, serving purposes that remain incompletely understood. They may have functioned as territorial markers, ritual foci, or monuments commemorating the dead. The stone's survival to the present day reflects both its substantial size and the remoteness of its upland location.
The monument's setting within the Cwm Irfon valley places it within a landscape of archaeological significance. The stone stands as a tangible link to the prehistoric peoples who inhabited this region, offering insights into Bronze Age settlement patterns and ritual practice in the Welsh uplands.
