Underground city

Part of Montreal's underground city, a concourse in Bonaventure metro station.

An Underground city is a series of linked subterranean spaces that may provide a defensive refuge, a place for living, working or shopping, a transit system, mausolea, wine or storage cellars, cisterns or drainage channels or several of these. The term may also refer to a network of tunnels that connects buildings beneath street level.[citation needed] These tunnels may house office blocks, shopping malls, metro stations, theatres, and other attractions. These passages can usually be accessed through the public space of any of the buildings connecting to them, and sometimes have separate entries as well. The latter definition encompasses many modern structures, while the former more generally covers tunnel systems from ancient times to the present day.

Underground cities are especially important in cities with cold climates, as they permit the downtown core to be comfortably accessible 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.

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.[1] 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,[2] with many expansions since then. Countries with underground cities include:

  • Sydney has a series of underground shopping malls around one of the city's underground stations Town Hall. The tunnels run south to the George Street cinema district, west under the town hall, and north to Pitt Street Mall through the Queen Victoria Building. The northern branch links Queen Victoria Building with Galleries Victoria, Sydney Central Plaza (which in turn links internally above ground to Westfield Centrepoint, Imperial Arcade, Skygarden, Glasshouse, and the MLC Centre). The linked centres run for over 3 km. In 2005 Westfield corporation submitted a development application to link Sydney Central Plaza underground with 3 other properties on Pitt Street Mall and extend the tunnel network by a further 500m.

  • Edmonton has a small system of tunnels and above-ground skyways called the Pedway connecting buildings and LRT stations of the downtown core.
  • Halifax (Downtown Halifax Link) where no point is more than 10 minutes casual walking distance from any other one.
  • Montreal Underground city, or la ville souterraine in French, is the largest underground network in the world. Its 32 km of tunnel cover more than 41 city blocks (about 12 km–). Access through the RÉSO can be made to apartment buildings, hotels, offices, banks, and universities, as well as public spaces like retail shops and malls, concert halls, cinemas, the Bell Centre hockey arena, museums, seven metro stations, two train stations (Lucien-L'Allier and Gare Centrale), a bus terminal (Réseau de transport de Longueuil and other transit authorities), and other areas. It connects 80% of office space and 35% of commercial space in downtown Montreal.
    • The network began as a connection between Place Ville Marie, the Queen Elizabeth Hotel and the Gare Centrale.
    • More than 2,000 shops and 40 cinemas line the passageways. Tourists often visit various attractions in the underground city, which is used by an average of half a million Montrealers per day.
    • Eight metro stations link to smaller networks that are not yet part of the central network, such as Berri UQAM in the eastern part of downtown, and Pie-IX which links venues from the 1976 Summer Olympics. Additionally, other underground networks exist that are not part of the metro system, such as the La Cité housing and retail complex.

In general, many large railway stations house underground hallways featuring shops, restaurants, banks and money exchange offices. A striking example of such stations would be the main hallway of the Amsterdam central station, which also connects to the city's metro system.

  • Maastricht: Originally a casemate, the kazematten of Maastricht form a 14 km long network of tunnels underneath the western part of the city.[3] This tunnel network has mainly been used for military purposes. The main construction period of these tunnels lasted from 1575 to 1825[3]. However, the newest sections of the tunnel network has been dug as late as the middle 20th century, built in the Cold War as a shelter for citizens in the event of a nuclear strike on the city[4]. Another, far more extensive system of tunnels with a total length over 200 km and 20,000 individual corridors lies just west of Maastricht; this is referred to as the Caves of Maastricht (Dutch:Grotten van Maastricht).[5] These man-made 'caves' were used as Marl quarries starting from the 13th century onwards [6]. In World War II, these caves were used to hide large quantities of paintings from the Germans, even including the Nachtwacht[7]. In 1944, construction started on a large public shelter that could have housed 45,000 persons in these caves. However, the project never saw its completion due to the liberation of Maastricht in the fall of the same year[8].

Expanding the network further, is the first phase of a new subterranean network linking the station to the up-coming One Raffles Quay development and with provisions to extend it into the Marina Bay new downtown extension for a complex underground pedestrian nework across the entire downtown area.
  • The Orchard Road shopping belt is connected by underground linkways often with commercial space, particularly around the three MRT stations serving the district, namely Orchard [2], Somerset [3], and Dhoby Ghaut [4]. Plans are in place to link all buildings along the road into a continuous underground network on both sides of the over four kilometre long road.

  • Cappadocia contains several historical underground cities carved out of unusual geological formations formed via the eruptions of ancient volcanoes. The cities were initially inhabited by the Hittites, then later by early Christians as hiding places (see [5]). They are now archeological and tourist sites, but are not generally occupied (see Kaymaklä� Underground City and Derinkuyu). The latest large underground city was discovered in 2007 in Gaziemir, Güzelyurt. This city was a stopover on the Silk Road, allowing travelers and their camels to rest in safety underground, in a 'fortress' equivalent to a modern hotel.
A typical view from inside the underground city in Derinkuyu, one of the largest underground complexes in Cappadocia. There are few artifacts left from the original builders, mainly just large rocks that was used to block the passage for intruders. Most of the "cities" are corridors, but some places there are rooms large enough to live in, and some rooms that have the cross-like shape of a church, which is probably exactly what they were.
  • Istanbul boasts the Roman cisterns, built 2000 years ago for water storage, but now a tourist attraction.

[edit] Ukraine

  • Kiev - An underground concourse extends underneath Khreschatyk Street from Maidan Nezalezhnosti to Ploscha L'va Tolstoho. The concourse connects to the Kiev Metro and to the Globe shopping mall beneath Maidan Nezalezhnosti.

  • Dover contains a series of interconnecting tunnels, that honeycomb both sides of the Dover Valley, carved into the chalk cliffs. These date from Ancient times at Dover Castle through to Napoleonic, Second and Cold War installations. The Dover Castle complex is the larger, going at least six levels deep and includes a hospital, troops quarters, offices and storage and channel view points. The southern tunnels are mixed between Napoleonic War-era defences (see Dover Western Heights ) and Second World War-era defences, with some seafront air raid shelters still used for shop storage today. Many have fallen into disrepair and are now closed to the public, but many are still open.

  • Atlanta, Georgia - Atlanta's 'Underground' actually represents the original surface level of downtown Atlanta; the present streets are in fact raised roadways (viaducts) built in the 1920s. The shopping center Underground Atlanta, taking advantage of the former street-level storefronts, covers six city blocks, and includes retail shopping and restaurants. It was begun in 1968, and re-opened in 1989 after a financially-forced closure. Underground Atlanta homepage
  • Walt Disney World, Florida (South-West of Orlando, Florida) has a network of tunnels utilized by its employees (Cast Members) for transportation between venues, rest, staff preparation, and first aid. The main system exists under the Magic Kingdom theme park. Other tunnels lie under future world at Epcot.
  • Duluth, Minnesota has a small network of skyways and tunnels connecting some buildings, including the Federal Courthouse and Convention Center (DECC).
  • Houston, Texas - The seven-mile (11 km) Houston tunnel system is set about twenty feet below Houston's downtown street system, and is composed of a series of underground passageways which, with above-ground skywalks, link office towers to hotels, banks, corporate and government offices, restaurants, retail stores, and the Theater District. Only one building, Wells Fargo Plaza, offers direct access from the street to the Tunnel; otherwise, you must enter the Tunnel from street-level stairs, escalators, or elevators located inside a building connected to the Tunnel.
  • Minneapolis and Saint Paul, Minnesota - There are three major systems consisting mostly of above-ground skyways in the Twin Cities. Minneapolis's skyway system covers approximately five miles with 62 skyways. St. Paul's skyway system connects buildings in a 30-block radius in the downtown core. [7] On the University of Minnesota campus, the Gopher Way connects most buildings and parking structures together using a number of skyway links and underground tunnels.
  • New York, New York - Several subway stations have direct access to one or more buildings. Additionally, most of the lower floor of Rockefeller Center qualifies as an underground city, as it features connections to subways, an extensive underground concourse, building connections, and several restaurants, all below ground.
  • Oklahoma City, Oklahoma - The Oklahoma City Underground, formerly the Oklahoma City Conncourse, named after its founder, Jack Conn, is an underground tunnel system connecting nearly all the downtown buildings in a 20-square-block area. The OKC Underground is one of the most extensive all-enclosed pedestrian systems in the country, extending three-quarters of a mile and connecting over 30 downtown buildings by tunnel or skyway. The original tunnel link was built in 1931 and the system was extended in the 1970s. Offices, shops, and restaurants line the OKC Underground system. It underwent a $2 million renovation in 2006-2007. Upon completion of the renovation, the Conncourse was renamed the Underground.[10][11]
  • Richmond, Virginia - There are a series of connected tunnels between state government buildings in the city of Richmond. Certain passageways are locked off but a good portion of the tunnels are accessible from different buildings. The purpose of the tunnels is not generally known; the two most common explanations are that they were built to allow people to move between buildings in inclement weather or that they were built as part of an emergency evacuation plan.
  • Rochester, Minnesota - The Mayo Clinic's various buildings in the downtown area are interconnected with tunnels and skyways. Various other businesses also exist along the corridors, including a number of hotels that often house clinic patients. It is often called a subway, although there are no underground rails in the city.
