Irish Round towers  were  built c.500 – c.1200 generally in the vicinity of monasteries and churches. Structurally, they conform to a specific design unique to Ireland. Given their great height (up to 40m/130ft) and with four windows located at the top facing the cardinal compass points, it is likely that round towers served as lookout towers and landmarks. They may also have served as repositories for the monastery’s treasures such as chalices and illuminated manuscripts.

Many historians believe that Irish round towers were primarily used as belfries. As such, they would have served various religious functions, such as calling the monastic community to prayer. The tolling of the bells may have warned the monks of impending danger also. Christian annals document that during Viking raids monastic communities sought refuge in round towers, although it is improbable that they were built with this purpose in mind.

Approximately sixty round towers have survived including some fine examples at Ardmore (Co.Waterford), Glendalough (Co.Wicklow) and the Rock of Cashel (Co. Tipperary).
