The shrine was built in Celtic architectural style, with its stained-glass windows crafted in Dublin, Ireland.
A side chapel honors St. Patrick with a life-size statue — shamrock in hand, snakes at his feet, recalling how he used the shamrock to explain the Holy Trinity and drove the snakes from Ireland. Its windows depict St. Columcille, St. Laurence O’Toole, St. Brigid, and St. Patrick.
The rose window over the main entrance centers on St. Patrick, ringed by symbols of Ireland’s four provinces — Ulster, Leinster, Munster, and Connaught. It was donated by Anna Waples in memory of her aunt Anna McDermott, the priest’s longtime housekeeper.
Windows throughout the shrine honor St. Michael the Archangel, St. Philomena, John the Baptist, St. Vincent de Paul, St. Joseph, and Mary and Jesus (in the shrine museum). Even the bell tower holds stained glass — St. Maria Goretti, St. Joan of Arc, and St. Oliver Plunkett.
Among its treasures from Ireland: the Croagh Patrick altar stone, the pilgrim-worn flagstone, and the Lough Derg chalice.
