London is both a bright, modern city with soaring skyscrapers as well as a metropolis hundreds of years old--and, despite its gleaming surface, there is another side to the city, one of secrets, dilapidation, and mystery. Wander through disused stations on the Underground; immense, ornate Victorian sewers and waterworks; crumbling but beautiful Art Deco cinemas and empty swimming pools; bombed-out churches and eerie docklands; and ruined mansions and overgrown cemeteries, all haunting relics from a time gone by. Arranged thematically from transport and industry to residential and recreational, these entries cover both the modern city and the historical metropolis.
