Underground City - United Kingdom

United Kingdom

• Corsham, Wiltshire is the location of the Central Government War Headquarters, code name 'Burlington'. Built in the late 1950s in response to the increasing threat of nuclear warfare during the Cold War, the 35 acres (1,524,600 sq ft) subterranean site was designed to be the main emergency government war headquarters of the UK outside of London and safely house up to 4,000 central government personnel in the event of a nuclear strike.
• In London's redeveloped docklands Canary Wharf tube station, adjacent office towers and shopping malls are connected underground. It is also possible to access two stations of the Docklands Light Railway without going outside;
• 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.
• London: There are extensive rooms, tunnels and chambers known as Churchill War Rooms or Admiralty Citadel beneath Whitehall, created during World War II, and used by Winston Churchill.
• There are extensive underground constructions across Britain, built as air-raid shelters during World War II.
• Edinburgh's old town has extensive rooms, tunnels and chambers beneath some areas.
• In Southport, Merseyside, Nevill Street has the remainders of an underground shopping street, which can now only be accessed from the cellars of buildings on the current street, which was raised by one storey from the original level. One end of the underground street ended at the Marine Lake, close to the pier entrance. ;
• in Liverpool, Merseyside, the Williamson's tunnels included the site of an 'underground house' complete with windows (concealed by work for public opening) and an extant and partially excavated 'banqueting hall'.
• Nottingham has an extensive network of man-made caves, dating back to the Dark Ages.
