Downing Street is in Whitehall in central London, a few minutes' walk from the Houses of Parliament and a little further from Buckingham Palace. The street was built in the 1680s by Sir George Downing on the site of a mansion, Hampden House. The houses on the south side of the street were demolished in the 19th century to make way for government offices now occupied by the Foreign and Commonwealth Office. "Downing Street" is used as a metonym for the Government of the United Kingdom.
