Scotland Yard (officially New Scotland Yard) is a metonym for the headquarters of the Metropolitan Police Service, the territorial police force responsible for policing most of London.
The name derives from the location of the original Metropolitan Police headquarters at 4 Whitehall Place, which had a rear entrance on a street called Great Scotland Yard. The Scotland Yard entrance became the public entrance to the police station, and over time the street and the Metropolitan Police became synonymous. The New York Times wrote in 1964 that just as Wall Street gave its name to New York's financial district, Scotland Yard became the name for police activity in London.
The force moved away from Great Scotland Yard in 1890, and the name New Scotland Yard was adopted for the subsequent headquarters. The current New Scotland Yard is located on Broadway in Victoria and has been the Metropolitan Police's headquarters since 1967. In summer 2013, it was announced that the force would move back to the former site of Scotland Yard, the Curtis Green Building, which is located on the Victoria Embankment and the headquarters will be renamed Scotland Yard.
The Metropolitan Police Service is responsible for law enforcement within Greater London, excluding the square mile of the City of London, which is covered by the City of London Police. Additionally, the London Underground and National Rail networks are the responsibility of the British Transport Police. The Metropolitan Police was formed by Robert Peel with the implementation of the Metropolitan Police Act, passed by Parliament in 1829. Peel, with the help of Eugène-François Vidocq, selected the original site on Whitehall Place for the new police headquarters. The first two commissioners, Charles Rowan and Richard Mayne, along with various police officers and staff, occupied the building. Previously a private house, 4 Whitehall Place (51°30′22″N 0°07′34″W / 51.50598°N 0.12609°W) backed onto a street called Great Scotland Yard.
