10 Downing Street, the local of British prime ministers since 1735, along with the White House as being the most significant political house anyplace in the world. Behind its black door have been taken the most important decisions affecting Britain for almost 280 years.
Although 10 Downing Street appears to be a modest-looking terrace house from the outside, one of the most important decisions affecting Britain have been taken behind its black front door for the last 275 years. The original residence is a portal to 100 rooms in several larger houses connected by a warren of hallways and staircases.
The area around 10 Downing Street has been a center of British government since at least the 11th century, when King Canute I established a royal palace there.
During the heavy attack of London in World War II, German bombs blemished 10 Downing Street’s kitchen and state rooms in October, 1940, while Churchill dined yards away in the Garden Room.
