Rhos-Dyrnog Standing Stone is a prehistoric standing stone located in Wales and protected by Cadw as a scheduled ancient monument under reference MG147. Like other upright stones of its type, it likely dates to the Bronze Age or earlier, serving ceremonial, territorial or commemorative purposes within its local community.
The stone rises from bedrock of Llandovery rocks, undifferentiated mudstone, siltstone and sandstone deposited during the Llandovery period of the Silurian age, roughly 430 million years ago. This geology has shaped the landscape of the surrounding area and would have been familiar to the prehistoric peoples who erected the monument.
Standing stones of this period typically marked important gathering places, burial sites or pathways across the landscape. The survival of Rhos-Dyrnog into the modern era, despite centuries of agricultural use and weathering, reflects both the durability of Welsh stone and the significance that local communities have attached to preserving such monuments. Its protected status ensures that this tangible link to Wales's prehistoric past remains accessible to future generations.
