Irish round towers – literally "bell house") are early medieval stone towers of a type found mainly in Ireland, with two in Scotland and one on the Isle of Man. Though there is no certain agreement as to their purpose, it is thought they were principally bell towers, places of refuge, or a combination of these. The towers were probably built between the 9th and 12th centuries.
