Montréal’s “Mary Queen of the World” cathedral is a scaled-down homage to St. Peter’s Basilica in Rome. Bishop Ignace Bourget oversaw its construction after the first Catholic cathedral here burned to the ground in 1852. Most impressive is the 76m-high (249-ft.) dome, about a third of the size of the Italian original. The statues standing on the roofline represent patron saints of the Québec region, providing a local touch. The interior is less rewarding visually than the exterior, but the ceiling and high altar are worth a look.
