Saint Louis Square is an urban square in Montreal's Plateau Mont Royal. Its eastern edge fronts onto Saint Denis Street, a major north-south artery. Square Saint Louis Street runs along both the square's northern and southern sides, while Laval Avenue runs along its western side.
The square is located on the site of the city's former reservoir, which was in use until 1852, after which it was replaced by the McTavish reservoir following the Great Fire of 1852. The square was created in 1876 and was named for two businessmen, brothers Emmanuel Saint-Louis and Jean-Baptiste Saint-Louis.The Project for Public Spaces has called the square "the closest thing to a European neighbourhood square you'll find this side of the Atlantic."
