TONIGHT PART TWO delaorden_ojeda VIDEO CLIC HERE Montreal Underground System Montreal's Underground City is the set of interconnected complexes (both above and below ground) in and around Downtown Montreal, Quebec, Canada. It is also known as the indoor city, and is the largest underground complex in the world. Not all portions of the indoor city are underground. The connections are considered tunnels architecturally and technically, but have conditioned air and good lighting as any building's liveable space does. Many tunnels are large enough to have shops on both sides of the passage. With over 32 km (20 mi) of tunnels spread over more than 12 km2 (4.6 sq mi), connected areas include shopping malls, apartment buildings, hotels, condominiums, banks, offices, museums, universities, seven metro stations, two commuter train stations, a regional bus terminal and the Bell Centre amphitheatre and arena. There are more than 120 exterior access points to the underground city. Each access point is an entry point to one of 60 residential or commercial complexes comprising 3.6 km2 (1.4 sq mi) of floor space, including 80% of all office space and 35% of all commercial space in downtown Montreal. In winter, some 500,000 people use the underground city every day. Because of its Underground City, Montreal is often referred to as the "Double-Decker City" or "Two Cities in One". Thanks Magik
