Whitehall is a road and area in the City of Westminster, Central London, England. The road forms the first part of the A3212 road from Trafalgar Square to Chelsea. It is the main thoroughfare running south from Trafalgar Square towards Parliament Square. The street is recognised as the centre of the Government of the United Kingdom and is lined with numerous departments and ministries, including the Ministry of Defence, Horse Guards and the Cabinet Office. Consequently, the name "Whitehall" is used as a metonym for the British civil service and government, and as the geographic name for the surrounding area.
