The Underground City
The most famous aspect of shopping in Montreal is the Underground City. Officially called RÉSO or La Ville Souterraine, the “city” is a set of interconnected complexes above and below ground throughout downtown Montreal. Safe and sheltered from the elements, this largest underground complex in the world, offers a huge range of goods and services as well as a handy way to get from place to place without weather or traffic problems.
With over 20 miles of tunnels spread over more than 5 sq miles, connected areas include shopping malls, hotels, banks, offices, museums, universities, seven metro stations, two commuter train stations, a regional bus terminal and the Bell Centre amphitheatre and arena.
No small wonder then that Montreal is often referred to as "Two Cities in one!”
