A long narrow church, 20.12m x 5.03m (Westropp), with no separation of nave and chancel. The walls at the W end of the church stand approx. 2 m high; the E end with its gable survives to full height. A sacristy (on N side of chancel) and S transept were added in the 15thc., as were a domicile or conventual buildings at the W end of the nave on the S side. The S doorway to the nave retains jambs only, which seem to be late medieval. Romanesque sculpture is found in the E gable window.
The early monastic site is said to have been founded by St Cronan of Tuamgraney, possibly in the 6thc. The church was granted to the Augustinian Canons of Clare Abbey by Domnall Mor mac Toirrdelbaig Ua Briain in 1189 (Gwynn and Gleeson, 1961, 208). It was mentioned in taxation records for 1302-06 and in 1421 was referred to as the conventual priory of St Mary, dependent on Clare Abbey. The monastery was officially suppressed c.1543 and was held by 'friars' in 1584. The buildings were repaired for parochial use in 1615 (Gwynn and Hadcock, 1970, 178).
