The Queen Mary Church of the World is the second largest church in Montreal, the third largest in Quebec, after St. Joseph's Cathedral in Montreal and St. Anne's Cathedral in Quebec. Built between 1870 and 1894, the church is spectacular in its overall appearance, with green domes and giant stone pillars in front of the door indicating the Baroque architecture of the New Renaissance era, and the 13 statues on the roof represent the patron saint of the thirteen parishes of Montreal. This is the only one in Montreal, unlike the 12 Christ apostles in front of St. Peter's Basilica in Rome. The interior of the church is very broad and magnificent, with many frescoes with religious stories, and the sun shines through the painted glass to add a touch of life to the dark church, accompanying us in mystery and reality. The cathedral altar is very characteristic, golden glitter, chic and beautifully crafted. The cathedral altar is handmade from purple copper, decorated with gold foil, shining gold, gorgeous and noble.
