Underground city (original) (raw)

An underground city is a network of underground tunnels that connect buildings, usually in the downtown area of a city. These may include office blocks, shopping malls, train and metro stations, theatres, and other attractions. An underground city can usually be accessed through the public space of any of the buildings connecting to it, and sometimes has separate entries as well.

Underground cities are especially important in cities with cold climates, as they permit the downtown core to be enjoyed year round without regard to the weather.

Underground cities are similar in nature to skyway systems and may include some buildings linked by skyways or above-ground corridors rather than underground.

Cities with underground cities include:

• Montreal (la ville souterraine) whose 32 kilometres of tunnels connect seven downtown metro stations and many important office towers and malls, with smaller tunnel systems in other parts of the city linking other attractions to metro stations. Montreal is famous for its underground city and it is often visited by tourists. Map of the underground city (PDF format)
