Colloquially known in the United Kingdom as "Number 10", is the headquarters of Her Majesty's Government and the official residence and office of the First Lord of the Treasury, an office now invariably held by the Prime Minister.
No.10 Downing Street is possibly the most photographed and famous front door of any politician in the western world.
The building is over 300 years old and contains around 100 rooms. The land on which Downing Street stands was originally bought in 1654 by Sir George Downing; the notorious spy for Oliver Cromwell. He intended that town-houses on this street be built “for persons of good quality to inhabit…”. In 1732, three buildings were offered to Sir Robert Walpole who commissioned William Kent to join them together to become No.10 Downing Street.
