The O'Briens of Thomond, who once ruled much of north Munster, founded this medieval Franciscan friary. It grew quickly into a huge foundation, with 350 friars and a famed school of 600 pupils by 1375. It was the very last school of Catholic theology to survive the Reformation. The building contains an exceptional wealth of fifteenth- and sixteenth-century sculptures carved in the local hard limestone, including one of St Francis himself displaying the stigmata. An arch between the nave and transept bears a remarkable image of Christ with his hands bound. Don’t forget to visit the sacristy, an impressive structure with a ribbed, barrel-vaulted ceiling. Take special note of the beautiful east window, with its five lancets.
