Tuamgraney catholic church is said to be the oldest Irish church still in use today . It was founded by St Cronan who was abbot of Clonmacnoise. The western portion of the church, with its lintelled doorway, is said to have been rebuilt by the Abbot Cormac O Killeen in 969, and the church is reputed to have been repaired again by Brian Boru, around 1000. The church now houses the East Clare Heritage Centre.
