Friar’s Heel” or the “Sunday Stone”


The Heel Stone was once known as “Friar’s Heel”. A folk tale, which cannot be dated earlier than the seventeenth century, relates the origin of the name of this stone:





The Devil bought the stones from a woman in Ireland, wrapped them up, and brought them to Salisbury plain. One of the stones fell into the Avon, the rest were carried to the plain. The Devil then cried out, “No-one will ever find out how these stones came here!” A friar replied, “That’s what you think!,” whereupon the Devil threw one of the stones at him and struck him on the heel. The stone stuck in the ground and is still there.





Some claim “Friar’s Heel” is a corruption of “Freyja’s He-ol” or “Freyja Sul”, from the Nordic goddess Freyja and the Welsh word for “way” or “Sunday”, respectively
