Whitehall, street in Westminster borough, London, England. Because of the many British government offices on the street, Whitehall has become a synonym for the government. The name derives from Whitehall Palace, first built for Hubert de Burgh in the 13th cent. and rebuilt for Cardinal Wolsey in the 16th cent. The Banqueting House, which was added (1619–22) by Inigo Jones, survives today and is used for official receptions. There is a World War I memorial cenotaph on the street.
