Afon Arthog Standing Stone is a prehistoric standing stone located in Wales and protected by Cadw under reference ME234. The monument rises from bedrock composed of Ordovician extrusive rocks, a sequence of mafic lava and mafic tuff formed during the Ordovician period some 485 to 444 million years ago. This ancient volcanic foundation provides the geological setting for the stone's placement in the landscape.
Standing stones of this type typically date to the Bronze Age, serving ceremonial, ritual or territorial functions within prehistoric communities. The stone at Afon Arthog would have been a notable landmark visible across the surrounding terrain, its position fixed within the geological framework of the locality.
The monument survives as evidence of prehistoric land use and settlement patterns in Wales. Its preservation under Cadw protection recognises its archaeological significance and its role in understanding the monumental traditions of Bronze Age Wales, when such stones were erected across the Welsh landscape as enduring markers of cultural and social importance.
