RÉSO: The Underground City That Won Its Argument with Winter
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.
Start
Place Ville Marie: The Basement
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.
Gare Centrale: The Older Basement
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.
Place Bonaventure: The First Deliberate Node
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.
Cathédrale Marie-Reine-du-Monde: The European Import
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.
Montreal Eaton Centre: The Network Catches the Street
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 McGill: The Spine
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.
Place des Arts: The Civic Node
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.
Quartier des Spectacles: The Resolution
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 Time to Visit
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.
Pro Tips
- •Enter at the Bonaventure Métro or Gare Centrale on a weekday morning; the network is signed throughout, and the Place Ville Marie food court rotunda is the canonical Stop 1 anchor
- •The Marie-Reine-du-Monde cathedral is the only deliberate surface beat; the stairs from 1000 de la Gauchetière reach the René-Lévesque sidewalk in under a minute
- •Métro McGill mezzanine is free to stand on; the platforms below require an STM fare (~$3.75 CAD), which the tour does not require you to pay
- •The Vincent Ponte fonds at McGill Library Rare Books and Special Collections is the primary archive of the network's master-plan documents; reading-room appointment required
- •The Canadian Centre for Architecture, 1920 rue Baile, holds the Affleck-Desbarats-Dimakopoulos-Lebensold-Sise fonds with Place Bonaventure and Place des Arts records
- •The Don Nerbas article in Urban History Review, volume 43 number 2, 2015, is the peer-reviewed source on William Zeckendorf and Place Ville Marie
Safety & Precautions
- RÉSO corridors can be confusing at first; follow the colour-coded signage to the named anchor (PVM, Bonaventure, McGill, Place des Arts) rather than trying to read the corridor by feel
- The Stop 4 surface beat requires crossing Boulevard René-Lévesque at the Mansfield signal; the boulevard is six lanes wide, and the safest crossing is at the marked intersection
- Sunday access is unreliable across most of the network; office-tower entries close, and some interior corridors are gated until Monday morning
- During the Festival international de jazz de Montréal (late June through early July) and Juste pour rire (mid to late July), Place des Festivals is heavily programmed and the resolution stop may require walking through active staging
- The 33 kilometre figure that appears on some tourism materials is not the Guinness-certified number; the Guinness category is largest pedestrian subway network, certified at more than 32 km in November 2023
