Downtown Montreal lies at the foot of Mount Royal, which is designated as a major urban park. The Downtown area contains dozens of notable skyscrapers — which, by law, cannot be higher than Mount Royal — including the aforementioned 1000 de La Gauchetière and 1250 René-Lévesque. The Tour de la Bourse is also a significant building in Montreal, as it is where all stock and derivative trades take place, and is also home to a successful program to encourage nesting peregrine falcons.

Just southeast of downtown is Old Montreal (Vieux-Montréal), an historic area with such attractions as the Old Port, Place Jacques-Cartier, City Hall, the Marché Bonsecours, Place d'Armes, Pointe-à-Callière Museum, and the Notre-Dame de Montréal Basilica. Architecture and cobbled streets in Old Montreal have been maintained or restored to keep the look of the city in its earliest days as a settlement, and horse-drawn calèches help maintain that image. Old Montreal was a worldwide port, but shipping has been moved further east to the Port de Montreal site, leaving the riverside area of Old Port/Vieux-Port as a recreational and historical area now maintained by Parks Canada. The most recent trip to the North Pole departed from this port. Old Montreal is also accessible from the downtown core via the underground city and is served by several STM bus routes and metro stations, ferries to the South Shore and a network of bicycle paths.
