A number of military
A large network of tunnels exists below London for a variety of communications, civil defence and military purposes;[1][2] 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.
Pindar
The most important military citadel in central London is Pindar, or the Defence Crisis Management Centre. The bunker is located underneath the Ministry of Defence Main Building in Whitehall, five floors below the buildings previously existing South Citadel.[3][4] Construction took ten years and cost £126.3 million. Pindar became operational in 1992, two years before construction was complete. Computer equipment was much more expensive to install than originally estimated as there was very little physical access to the site. Pindar can house a maximum of 400 personnel and provides protection against conventional bombing, sabotage, biological and chemical attack, flooding, EMP attack, and the effects of blast, radiation and EMP from a nuclear weapon, but it is not designed to withstand a direct hit from a nuclear weapon.[4]
Pindar's has two floors; the lower floor contains the Ministry of Defence's Joint Operations Centre, and the upper floor consists of:[4]
- Government Emergency Rooms (comprising the Prime Minister, Secretaries of State, the Cabinet Secretary, and some Permanent Secretaries)
- An element of the Joint Intelligence Organisation
- A telecommunications secretariat and a Cabinet Office Communications Centre (COMCEN) element
Pindar is connected to Downing Street and the Cabinet Office by a tunnel under Whitehall, which can be used by Ministers to enter Pindar without the press knowing, in order not to damage morale.[4][5]
Although the facility is not open to the public, it has had some public exposure. In Fighting the War, a BBC documentary on the Iraq conflict broadcast in 2003, BBC cameras were allowed into the facility to film a small part of a teleconference between ministers and military commanders. Also, in 2008 the British photographer David Moore published his series of photographs The Last Things, widely believed to be an extensive photographic survey of Pindar.[6][7] His photographs show that it has stores including toothpaste, toothbrushes, and mouthwashes. It has bunks for up to 100 military officers, politicians and civilians as well as communication facilities, a medical centre and maps.[8]
The name Pindar is taken from the ancient Greek poet, whose house alone was left standing after Thebes was razed in 335 BC.[8]
Admiralty Citadel
The Admiralty Citadel, London's most visible military citadel, is located just behind the
Its brutal functionality speaks of a very practical purpose; in the event of a German invasion, it was intended that the building would become a fortress, with
In 1992 the Admiralty communications centre was established here as the stone frigate HMS St Vincent, which became MARCOMM COMCEN (St Vincent) in 1998. The Admiralty Citadel is still used today by the Ministry of Defence.
Cabinet War Rooms
The only central London citadel currently open to the public is the
The War Rooms were constructed in 1938 and were regularly 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 a popular tourist attraction 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 adjacent, 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 and other original artefacts on the desks. Churchill slept in a small bedroom nearby. There is a small telephone room (disguised as a toilet) down the corridor that provided a direct line to the
Q-Whitehall
Q-Whitehall is the name given to a communications facility under Whitehall.
The facility was built in a 12 ft (3.7 m) diameter tunnel during World War II, and extends under Whitehall. A similar facility was constructed in a tunnel that ran parallel to the Aldwych branch of the Piccadilly Line and was known as Trunks Kingsway (
Sites equipped with unusual amounts of GPO/BT telecommunications plant are given a BT site engineering code. This site's code was L/QWHI.
The site provided protected accommodation for the lines and terminal equipment serving the most important government departments, civil and military, to ensure the command and control of the war could continue despite heavy bombing of London.
At the northern end, a tunnel connects to a shaft up to the former
Access to the tunnel is gained via an 8 ft (2.4 m) lateral tunnel and a lift shaft in the nearby Whitehall telephone exchange in Craig's Court. A further entrance is via the deep level portion of the Admiralty.
Spur tunnels, 5 ft (1.5 m) in diameter, were built to provide protected cable routes to the major service buildings either side of Whitehall.
The Whitehall tunnels appear to have been extended in the early 1950s. Some official documents refer to a Scheme 3245: this is the only numbered tunnel scheme that has never been officially revealed or located by researchers. Files in the
The journalist Duncan Campbell managed to get into the BT deep level cable tunnels below London, and described his adventure in a New Statesman article in 1980. He found a (closed) entrance to Q-Whitehall below Trafalgar Square, and created a number of tunnel maps based on his investigation.[13]
