1200 Rue de Bleury
It does not look like much today from the outside but this church has seen a lot. According to Wikipedia, the Gesù witnessed the first “electric candle” lit in Canada in 1878. Built in 1864-1865, it is one of the oldest religious buildings in Montreal.
It used to be Collège Sainte-Marie Chapel where the Society of Jesus supported education. The Church of Gesù is actually the only portion of the college still standing today. The walls of the college remain and a commemoration of the Society of Jesus is just outside the church. Today, the amphitheater is used for presentations.
