Standing Stone above Craig Rhiwnant is a prehistoric standing stone located in Wales and protected by Cadw under reference BR210. The monument rises from bedrock composed of Ashgill Rocks—undifferentiated mudstone, siltstone and sandstone deposits formed during the Ashgill period of the Ordovician era. This geological foundation of fine sedimentary layers characterizes the upland terrain surrounding the site, with the stone anchored into these ancient marine deposits that accumulated over 440 million years ago.
The standing stone belongs to a class of prehistoric monuments common across Wales and beyond, typically erected during the Bronze Age or Neolithic period, though precise dating remains uncertain without excavation. Such stones often marked territorial boundaries, burial sites, ritual centres, or served as waymarkers across difficult upland terrain. Their survival depends partly on the stability of underlying bedrock; the mudstone and siltstone bedrock here provided sufficient firmness to support the monument through millennia.
The stone's setting above Craig Rhiwnant, positioned on the slopes overlooking this natural feature, suggests deliberate placement within the Bronze Age landscape. The exposed position would have made it visible across considerable distances, typical of standing stones that commanded views across valleys and ridgelines. Today it remains one of many such monuments preserving evidence of prehistoric land use and ceremonial practice in the Welsh uplands.
