Possibly the most famous underground cities are Montreal's RÉSO, used
by more people than any other locale and is the largest underground
city network in the world, and Toronto's PATH, which according to
Guinness World Records is the largest underground shopping complex in
the world with 371,600 square metres of retail space. Japan's
underground networks, while individually smaller, are the most
extensive overall with an estimated 76 underground shopping streets
totalling over 900,000 square metres of floor space in 1996, with many
expansions since then.
