Gwern-Wyddog Standing Stone is a prehistoric standing stone located in Wales. The monument stands upon bedrock of Lower Devonian age, comprising mudstone, siltstone and sandstone laid down during the Early Devonian period over 400 million years ago. This geology provided the local stone resource from which the monument was likely fashioned. The stone is protected by Cadw, the Welsh heritage body, under reference BR144, ensuring its preservation as an important archaeological record of prehistoric Wales.
Standing stones such as Gwern-Wyddog are monuments of Neolithic or Bronze Age origin, erected as markers, territorial boundaries or ceremonial foci within the landscape.
