Built in 1829, the neo-Gothic Basilique Notre-Dame is built in the scale and manner of Europe's great churches. It's said that the protestant architect James O'Donnell, who designed the basilica, was so taken with the project that he converted to Catholicism. Fine woodwork, rose ceiling windows, blue vaulted ceilings and a massive church bell make this a great place to visit. A small, on-site museum displays various religious artifacts, paintings and vestments.

This historic church is the seat of the city's Anglican Church. Built between 1857 and 1859, the neo-Gothic structure was designed to emulate a 14th-century English cathedral. The church sits atop Les Promenades de la Cathedrale, a popular city mall.

This cathedral stands in the heart of the city's Anglo-Protestant district and is a one-fourth-scale replica of Saint Peter's in Rome. The structure was built in 1894 and designed to deliberately intensify the effect of burning candles. The high altar features a replica of Bernini's vast baldachin in Saint Peter's. The first chapel in the left aisle is a red-flocked sanctuary filled with medals and saintly relics.

This small chapel, Montréal's oldest church, dates back to 1657. Margaret Bourgeoys, who founded the Notre Dame congregation of nuns, initiated construction, originally to provide sailors a refuge of peace and comfort. Legend has it that Montréal's founder, Paul Chomedey, personally cut timbers for the small chapel. A statue, "Our Lady of Good Hope" (hence "de Bon Secours"), was donated by the French. The statue reaches out her arms to protect sailors from the treacherous seas. The Marguerite Bourgeoys Museum on site has exhibits of historical and archaeological interest.

Built in 1904, this is one of the world's most popular Catholic shrines. The Renaissance-style dome was the world's largest when completed in 1955. The shrine now holds a museum, a tomb, monuments, a 56-bell carillon and Stations of the Cross in a sculpture garden. Features summer organ recitals on Wednesday evenings.
