 Upon investigation, it wasdiscovered that an ox, belonging to the local Druid came down from the mountain (The Mournes) each night and razed the building.One of the monks cut a thorn stick and stuck it into the ground between the ox's meadow and the new church.The stick grew into a thorn bush and the monk defied the ox to pass the thorn bush - it never did and the building of the church was completed.
