Cathal Crobderg O'Conor won a battle here, on a hill above the River Abbert in north-east County Galway, and decided the moment deserved an abbey. The year was 1189. He brought in Cistercian monks from Boyle Abbey in County Roscommon to settle the new house, and named it after the victory: Mainistir Chnoc Muaidhe, the Monastery of the Hill of Victory, or in Latin, Monasterium Collis Victoriae. After the dissolution, parishioners knew it as Porta Magna - the Great Door. Today, locals still call it Teampollandorusmoir, the Chapel with the Big Door, though the building is mostly roofless. What endures, weathered into the stone of the chancel's north wall, is a series of medieval paintings unlike anything else surviving in Ireland.

The Cistercians rebuilt and contin...
