On Wednesday, 17 August 2022, there was a remarkable discovery of carvings on one of the stones of Grange Stone Circle at Lough Gur, County Limerick, by Ken Williams, a leading Irish archaeological photographer.

He has developed methods of lighting stones to photograph them to maximum effect and he has found a number of new carvings over the years in this way.
