Llanfyrnach Standing Stones is a prehistoric standing stone monument located in Wales and protected by Cadw under the reference PE351. The stones rise from bedrock composed of Caradoc Rocks, an undifferentiated sequence of mudstone, siltstone and sandstone laid down during the Caradocian period. This geological foundation, typical of the region's Ordovician heritage, provided the local stone from which such monuments were fashioned.
Standing stones of this type were erected across Britain and Ireland from the Neolithic through Bronze Age periods, serving purposes that likely combined territorial marking, ritual significance and communal identity. The Llanfyrnach example testifies to the monumental ambitions of prehistoric Welsh communities and their engagement with the landscape.
The monument survives as a record of early stone-working capability and the symbolic importance ancient peoples attached to standing upright stones within their settled territories. Its preservation under statutory protection acknowledges both its archaeological significance and its role in understanding the prehistoric heritage of Wales.
