We came here as part of a tour group, and SO glad we did! This place is amazing! A must see if you come to Montreal! You could literally spend hours in here. So many details, so magnificent! It was hard to take everything in because there is so much to see, the stained glass, the statues, the carvings, the altar, the pipe organ. PLEASE go and see for yourself, you won't be disappointed. You don't have to be religious, the place is truly a work of art!
