London's West End

The West End of London (commonly referred to as the West End) is an area of Central and West London containing many of the city's major tourist attractions, shops, businesses, government buildings and entertainment venues, including the West End theatres.

Use of the term began in the early 19th century to describe fashionable areas to the west of Charing Cross. The West End covers much of the boroughs of Westminster and Camden.

While the City of London, or the Square Mile, is the main business and financial district in London, the West End is the main commercial and entertainment centre of the city. It is the largest central business district in the United Kingdom, comparable to Midtown Manhattan in New York City, the Gangnam District in Seoul, Shibuya in Tokyo, Sol in Madrid or the 8th arrondissement in Paris and EUR in Rome. It is one of the most expensive locations in the world in which to rent office space, just behind Silicon Valley's Sand Hill Road.

Lying to the west of the historic Roman and Medieval City of London, the West End was long favoured by the rich elite as a place of residence because it was usually upwind of the smoke drifting from the crowded City. It was also close to the royal seat of power at Westminster, and is largely contained within the City of Westminster (one of the 32 London boroughs).
