Clonmacnoise
Cluain Mhic Nóis
Ireland's most important early monastic site, founded in AD 544, with round towers, high crosses and church ruins on the banks of the Shannon.
Clonmacnoise was founded in 544 by Saint Ciarán and was once Ireland's religious and scholarly center, where successive High Kings were buried. The site contains a cathedral, seven small churches, two round towers and hundreds of early Christian grave slabs. The original 'Cross of the Scriptures' is displayed inside the visitor center, and a replica stands outdoors. The site overlooks the Shannon River and its wetland meadows, with wide views.
It is managed by the Office of Public Works (OPW) and charges admission, which includes the exhibitions and a short film. It is open year-round, though it closes earlier in winter. The site lies about 20 km south of Athlone with no convenient public transport, so drive or join a tour. Allow 1.5 to 2 hours for a visit.
