Montreal did not plan an underground city. It planned one basement in 1958, then a second, then a Métro, and woke up to discover the world's largest pedestrian subway network. Walk it with the planner's eye.

Place Ville Marie: The Basement

The original 1962 basement. Henry Cobb of I. M. Pei's office designed the cruciform tower for William Zeckendorf. The shape of the basement is the shape of the tower above it. The network begins here, by accident.

Opened 14 July 1943. John Schofield of Canadian National Railways. The 1929 Act that authorized this station also authorized an explicitly underground urban-development scheme. The first thousand metres of RÉSO is nineteen years older than Place Ville Marie.

Opened 1967. Affleck, Desbarats, Dimakopoulos, Lebensold, Sise, with Raymond T. Affleck as lead architect and Eva Vecsei as associate in charge of design. Private development by Concordia Estates on CN's air rights. The first building designed from the start to plug into the network.

Built 1870-1894 by Victor Bourgeau and Rev. Joseph Michaud. Consecrated 1894 as Saint-Jacques Cathedral. Rededicated 1955 as Mary, Queen of the World, by Pope Pius XII at Cardinal Léger's request. Adjacent to RÉSO, not on it. The above-ground beat that explains why the network worked here.

Opened 14 November 1990 on the site of demolished mall Les Terrasses. Connected to RÉSO at the lower concourse. The moment the network crossed from financial-district amenity to popular-city shopping street.

Métro opened 14 October 1966 under chief engineer Lucien L'Allier of the Bureau du métro. MR-63 cars built by Canadian Vickers in the Viauville shipyards on the Paris MP 59 rubber-tired model. Without the 1966 Métro, RÉSO would have stayed a handful of basement connections.

Salle Wilfrid-Pelletier opened 21 September 1963. Affleck, Desbarats, Dimakopoulos, Lebensold, Michaud and Sise, an initiative of Mayor Jean Drapeau. The publicly owned cultural complex that proves RÉSO is a civic network, not a corporate one.

Place des Festivals, the open-air heart of Quartier des Spectacles. The network surfaces here. The two cities, the one below and the one above, are the same city, walked twice.
Best walked Tuesday through Thursday, 10 a.m. to 4 p.m. Most RÉSO segments are open weekdays and Saturdays; some sections close Sundays and late evenings, and most office-tower entries are closed on weekends. The tour is functional on Saturdays with degraded access, not recommended on Sundays. The seven indoor stops are reliably accessible during weekday business hours. The two outdoor stops (cathedral plaza and Place des Festivals) are accessible at any hour, year-round; the indoor stops are the network itself.
