Earliest records show that this stone was known as 'Carreg Ateb' (Answer Stone) as calling across the river at this point produces an echo.
Legend has it that the Abbot of St Dogmaels blessed the river and fishing boats here, hence its modern name. The tradition has recently been revived.
What is now called The Blessing Stone may well have been the capstone of a dolmen (from the Breton tol-maen - 'stone table') that stood on level ground above, where the view is spectacular. Nearby, lie other stones that may have been the uprights originally used to support the capstone. Within 7 miles of St Dogmaels there are many dolmens, most notable being Pentre Ifan, Llech-y-Drybedd, Trellyffant and Carreg Coetan Arthur. The Blessing Stone is of a very similar shape to the Llech-y-Drybedd capstone. Capstone shapes often mirror the local landscape.
