Headquarters of the London Metropolitan Police, and, by extension, the force itself. The London police force was created in 1829 by Sir Robert Peel and housed at 4 Whitehall Place, which had an entrance in Great Scotland Yard. In 1890 it moved to a new building; that location became New Scotland Yard, a name that was kept when it moved again in 1967. In addition to duties common to all metropolitan police forces (including crime detection and prevention and traffic management), it is entrusted with civil defense in times of emergency, and it maintains a special branch for guarding visiting dignitaries, royalty, and political dignitaries. It keeps records on all known criminals in Britain, and other British police forces often seek its assistance. It also helps train the police of Commonwealth nations.
