About Saint-Louis Square#

Saint-Louis Square is a small, formal public square in Montreal’s Plateau-Mont-Royal neighbourhood surrounded by compact streets and Victorian-era residential buildings. The square is noted for its mature trees, sidewalks and the residential facades that frame its open lawn and paths.

The setting makes it a frequent local meeting place and a visual highlight of the Plateau for pedestrians, photographers and nearby residents. The square sits within a dense urban neighbourhood and provides a pocket of green close to shops, restaurants and cultural venues.
