Try your hand at carving a stone masons marks using traditional stone carving tools. Stonemasons used this signature mark on stones to make sure they were payed for the work they did, also see the carvings that were distinct to each mason. Using Dudry stone which is the stone used in the windows of Christchurch Cathedral here in Dublin you can watch a demonstration of how a mark would have been carved. If you are not in a hurry you can have a go and maybe even bring a piece of carved stone away with you.
Happening on Saturday the 4th of July from 11am to 4pm.
