The White House is undoubtedly the most recognisable structure in Washington DC. Home to the President of the United States since its completion in 1800, the White House is the only presidential residence in the world to be open to the public and has become a symbol not only of the presidency and the govenment, but also of the Unites States as a whole. Tickets and tours are available from the White House visitors center.
