Clonmacnoise Monastic Site

The monastery of Clonmacnoise is situated in County Offaly, Ireland on the River Shannon south of Athlone. Clonmacnoise was founded sometime between 545 and 548 by Ciarán Mac a tSaor, a young man from Rathcroghan, Co. Roscommon. Until the 9th century it had close associations with the kings of Connacht. The strategic location of the monastery helped it become a major centre of religion, learning, craftsmanship and trade by the 9th century and together with Clonard it was the most famous in Ireland, visited by scholars from all over Europe. From the ninth until the eleventh century it was allied with the kings of Meath. Many of the high kings of Tara and Connacht were buried here.
