Directly behind the observation deck overlooking downtown is Mount Royal Chalet. The special event venue was created during the height of the Great Depression to generate work for the unemployed. The architect for the one-story, French Beaux Arts structure was Aristide Beaugrand-Champagne. Chalet du Mont-Royal is a prominent feature of Mount Royal Park. The 692 acre greenspace was established in 1876. Parc du Mont-Royal was designed by the most famous landscape architect in America: Frederick Law Olmsted. Among his other project credits were Central Park in New York City and the grounds encircling the United States Capitol building.
