Under Ground reveals the history of six major subways - London, Paris, Moscow, New York, Berlin, Tokio - and also shows in stunning photographs almost 50 stations notable for their artistic and architectural beauty, the genius of their innovative design, the welcoming and accessible facilities, clockwork efficiency, and historic and cultural symbolism. The marvel is that they all feature something you would not expect to encounter underground, and are worthy of a visit even if you are not a passenger.
