The term was first used in the early 19th century to describe fashionable areas to the west of Charing Cross.
Then during the late 17th, 18th and 19th centuries, it was built as a series of palaces, expensive town houses, fashionable shops and places of entertainment.
The areas closest to the City around Holborn, Seven Dials, and Covent Garden contained poorer communities that were cleared and redeveloped in the 19th century.
As the West End is a term used colloquially by Londoners and is not an official geographical or municipal definition, its exact constituent parts are up for debate.
The Edgware Road to the north-west and the Victoria Embankment to the south-east were also covered by the document but were treated as "adjacent areas" to the West End.
