"Driving around Montreal, you might notice a big, rounded, green roof standing tall on the horizon. That roof belongs to St. Joseph’s Oratory of Mount Royal, the largest church in Canada and a popular destination for locals and visitors alike. At 97 metres, that huge roof — the dome of the Oratory basilica — is the second highest in the world, behind only Saint Peter’s Basilica in Rome."
