More than 40 feet underground in suburban London lies one of the great secrets of World War II. The British government decided after the first world war that should a similar war happen again, it would be prudent to have a second secure location for the most senior ministers to escape to and continue running a war.

For these alternate Cabinet War Rooms (codename “PADDOCK”), they chose Dollis Hill, a sleepy part of north-west London notable only for the drab Post Office Research Centre where many of the nations technological achievements were made (the first electronic computer, Colossus, is said to have been invented here). Paddock was a bomb-proof facility over three floors, 22 rooms underground, big enough to house more than 200 staff, and intended to be able to run a major war from. It was not until 1997, when a housing development company bought the land, that the public was informed of the location of the bunker. A deal was struck - the housing development could go ahead, but the bunker was not to be demolished. Custodianship was granted on the proviso that the bunker is opened to the public once or twice a year. A group known as Subterranea Britannica look after the bunker.

Churchill held the first Cabinet meeting at the bunker in October 1940, “We held a Cabinet meeting at PADDOCK far from the light of day, and each Minister was required to inspect and satisfy himself about his sleeping and working apartments. We celebrated this occasion with a vivacious luncheon, and then returned to Whitehall.” It is fair to say that he was not impressed with the facility. “The accommodation at Paddock is quite unsuited to the conditions which have arisen,” he wrote. “Paddock should be treated as a last resort.”

Visiting the bunker, you can not help but notice the absurdities. A secret secure bunker situated underneath an important communications target. It was built to withstand the biggest bombs of the day, but water leaks in everywhere. There are no toilets underground. Although 200 staff could work in the bunker, the kitchen is barely the size of a typical modern household kitchen. Yet it has a large map room, cabinet room, sleeping quarters for Churchill, separate areas for Army, Navy, and Air force. A room is dedicated for BBC broadcasts (rumour has it that the actor David Niven was to impersonate Churchill’s voice in broadcasts, should anything happen to the Prime Minister).

Thankfully, the Sub Brits have only partially restored the bunker. Much of the water has been pumped out, but the floors are still slippery, handrails slimy, and rooms smelly. Long stalagtites of calcium hang from the ceiling, the concrete giving up its raw materials. It is all very surreal. This is Churchill’s quarters. This is where the war cabinet met after the Battle of Britain. This is where the BBC would broadcast. These doors protect against mustard gas. Mind your head on the way out.

On the day I visited, a good twenty to thirty others made the trip down. One fellow was on his third visit, and had brought his own flash light. A young couple posed for digital photographs of each other in the map room. Some older folk, who must have been children during WWII, visiting for reasons of nostalgia I assume. We took the opportunity to see some almost-forgotten history.



Want more photographs? Here is most of the rest of my roll: 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19.
