This 6th century stone, also known as the Pumpeius stone, is now housed in Margam Stones Museum. It was photographed on the side of the road known as 'Water Street', the presumed line of the Roman road between the forts of Cardiff and Neath. Amgueddfa Cymru has a cast of the stone in its collection.
