Built in 1847, this is one of the purest examples of the Gothic Revival style in Canada, with a high-vaulted ceiling glowing with green and gold mosaics. The tall, slender columns are actually pine logs lashed together and decorated to look like marble, so that if you stand in one of the back corners and look toward the altar you really do feel as if you're peering at the sacred through a grove of trees. St. Pat's—as most of its parishioners call it—is to Montréal's Anglophone Catholics what the Basilique Notre-Dame is to their French-speaking brethren—the mother church and a monument to faith and courage. One of the joys of visiting the place is that you'll probably be the only tourist there, so you'll have plenty of time to check out the old pulpit and the huge lamp decorated with six 2-meter- (6-foot-) tall angels hanging over the main altar. And if you're named after some relatively obscure saint like Scholastica or Aeden of Fleury, you can search for your namesake's portrait among the 170 painted panels on the walls of the nave.
For a solemn experience visit on the third Sunday of the month (September through to June) where the mass is sung completely in Latin.
