A cathedral inspired by St. Peter’s Basilica
Mary, Queen of the World Cathedral is the seat of the Roman Catholic Archdiocese of Montréal. Its design looks to St. Peter’s Basilica in Rome, but the Montréal building is a quarter-scale replica. The dome, columns and pediment carry the influence of the Roman model into the city’s downtown.
The choice of style also had a local context. In 19th-century Québec, Gothic Revival churches were often associated with Protestantism, while neoclassical design was more typical of Catholic buildings. The cathedral’s formal exterior reflects that preference. Construction was mostly completed by 1894, and the building became a National Historic Site of Canada in 2000.
Details to look for inside
The interior’s central feature is a baldachin modeled on the work of Gian Lorenzo Bernini in St. Peter’s Basilica. Look up at the dome, then take in the red copper and gold-leaf altar and the detailed decoration around the main space. The cathedral also contains nine paintings and large statues representing the 13 parishes of 19th-century Montréal.
Among the works of art are a crucifix by Philippe Hébert and a marble-decorated chapel with a stucco crucifix. Stained-glass windows and painted scenes add further detail. Give yourself time to notice the craftsmanship at different levels, from the altar to the ceilings.
