There is a tomb-stone in Emly grave yard. It is know as St. Ailbe's Cross. It is a Celtic cross. It is a very ancient cross. It is worn away now. It is made of granite stone. It is situated in the south western part of the graveyard. There is no stone in the graveyard like it.The stone is four feet eight inches high and one foot ten inches wide. People say that more than half of it exists under the ground. There is no writing and no carving on it now. The weather has worn it away from time to time. St Ailbe is buried to the west of the stone. There was a monastery opposite the stone but it does not exist now.The Sign of the Cross is made by the people on it with three stones which are laid on top of it. Long ago the people used swear by the Holy Stone of Emly. Every time people respect it as they pass it by carving a cross on it with stones. When a person has a pain in his back he would get it cured by putting his back against the stone and praying to St Ailbe. When a person has no pain in his back and to do the same it would strengthen his back.
