[3] The zone contains all the central London districts, most of the major tourist attractions, the major rail terminals, the City of London, and the West End.
[4] London is split into six approximately concentric zones.
Zone 1 covers the West End, the Holborn district, Kensington, Paddington and the City of London, as well as Old Street, Angel, Pimlico, Tower Gateway, Aldgate East, Euston, Vauxhall, Elephant & Castle, Borough, London Bridge, Earl's Court, Marylebone, Edgware Road, Lambeth North and Waterloo.
Every London Underground line has stations in zone 1.
Underground stations within this zone are typically close together; for instance Covent Garden and Leicester Square are only 0.3 kilometres (0.2 mi) apart, the shortest distance between any two stations in the network.
