Saint Joseph's Oratory
The only building in Montreal that breaches the bylaw barring any structure from surpassing Mount Royal — rising more than 30 metres above its summit.

Brother André's 1904 miracle-healing reputation funded a 4.5×5.5-metre chapel that kept expanding for six decades into Canada's largest church, with one of the largest church domes in the world. A C$80 million renovation begun in 2018 is adding first-ever public access to the lantern for a 360-degree view over the city.
What to look for
- The Renaissance Revival facade outside versus the Art Deco interior — a deliberate clash built across multiple architects and six decades
- The original chapel (4.5 by 5.5 metres) still standing on site, relocated about 100 metres from where Brother André first opened it
- The dome and lantern under active renovation — scaffolding marks the C$80 million project by Atelier TAG and Architecture49
Address: 3800 Queen Mary Road, Côte-des-Neiges; the Oratory is visible from kilometres away and draws over 2 million visitors a year, so arrive early on weekends.
