The Lucky Stone at St. Audoen's Church, Dublin, which is possibly a grave marker from the grounds of nearby St. Patrick's during the early Christian period. It's had a few adventures in its time - being stolen, and moved around. The stone is said to glow, jump and shake, groan and even take on a human form! Touching the stone is said to bring luck....One of the oldest existing churches in Dublin, St. Audoens is a Norman church to St Ouen, built in 1190 to replace an earlier church to St Colmcille. The three bells in the belltower are reported to date to 1423. The mysterious Lucky Stone, an early Christian grave marker, is in the porch, where it has been since 1309. The main porch also houses the Portleister Tomb, featuring two carved effigys of the church benefactor and his wife. .
