Whitehall is a road in the City of Westminster, in central London, which forms the first part of the A3212 road from Trafalgar Square to Chelsea. It is the main thoroughfare running south from the site of the original Charing Cross at the southern end of Trafalgar Square towards Parliament Square. Recognised as the centre of Her Majesty's Government, the street is lined with government departments and ministries; the name "Whitehall" is thus also frequently used as a metonym for British central governmental administration, as well as being a geographic name for the surrounding area.
