Giantsgrave

These pics are a couple of years old now. I happen to have passed the sign for this a few weeks ago and remembered I had called up here before.
Its a standing stone with two crosses on it, one incised into it the other standing out from the face. With a name like Giantsgrave you would think it was a megalithic tomb but this stone doesnt look like it could have been used in a tomb.
The standing stone is well sign-posted on the Clonmel to Cashel road.
