context_page_description: A number of military citadels are known to have been constructed underground in central London, dating mostly from the Second World War and the Cold War. Unlike traditional above-ground citadels, these sites are primarily secure centres for defence co-ordination.
  A large network of tunnels exists below London for a variety of communications, civil defence and military purposes, however it is unclear how these tunnels, and the various facilities linked to them, fit together, if at all. Even the number and nature of these facilities is unclear; only a few have been officially admitted to.
context_section_description: The only central London citadel currently open to the public is the Cabinet War Rooms, located in Horse Guards Road in the basement of what is now HM Treasury. This was not a purpose-built citadel but was instead a reinforced adaptation of an existing basement built many years before. 
  The War Rooms were constructed in 1938 and were heavily used by Winston Churchill during World War II. However, the Cabinet War Rooms were vulnerable to a direct hit and were abandoned not long after the war. The Cabinet War Rooms were a secret to all civilians until their opening to the public in 1984. They are now maintained by the Imperial War Museum.
  The section of the War Rooms open to the public is in fact only a portion of a much larger facility. They originally covered three acres (1.2 hectares) and housed a staff of up to 528 people, with facilities including a canteen, hospital, shooting range and dormitories. The centrepiece of the War Rooms is the Cabinet Room itself, where Churchill's War Cabinet met. 
  The Map Room is located nearby, from where the course of the war was directed. It is still in much the same condition as when it was abandoned, with the original maps still on the walls and telephones lining the desks. Churchill slept in a small bedroom nearby. There was a telephone room down the corridor that provided a direct line to the White House in Washington, DC, via a special scrambler in an annexe basement of Selfridges department store in Oxford Street.
