The Saint Joseph's Oratory of Mont-Royal is an amazing church with a rich, interesting history. The architecture is incredible and awe-inspiring, and it definitely gives you a sense of wonderment. I'm sure if I lived in Montreal I would only attend Mass here on occasion because the grandeur is so eye catching that it would distract me. But as a destination and a thing to see in Montreal, this is truly a special one.
There are some stairs, and an elevator that cuts out the elevation, and the lookout points have some incredible views. There is much to explore at the Oratory, so be sure and plan ahead so you see it all.
It is Canada's largest church, and a national shrine. and a reliquary in the church museum contains Brother Andre's heart the Saint who founded the church as a small chapel back in 1904.
