The Underground City
Place Ville Marie, the cruciform skyscraper designed by I. M. Pei, was the tallest structure in the city when it opened in 1962. Located in the heart of Downtown, it was the birthplace of Montréal's subterranean city. Montrealers were skeptical that anyone would want to shop or even walk around in the new "down" town, but six decades later they can't live without it, especially in winter.
About half a million people use the 32-km (20-mile) Underground City, or la ville souterraine, daily. The tunnels link 10 métro stations, seven hotels, 200 restaurants, 1,700 boutiques, and 60 office buildings—not to mention movie theaters, concert halls, convention complexes, Centre Bell, two universities, and a college. In 2004, the Underground City was rebranded as the RESO, a play on the word réseau, which means network. You'll see the signs for it in the Downtown area and can find a map of the network online ( montrealvisitorsguide.com/the-underground-city-map).
