<p>Peter Dazeley has gained access to the hidden interiors of some of London's most iconic buildings, from Tower Bridge to Battersea Power Station, Big Ben to the Old Bailey. His photographs of these buildings - some derelict, but many still working - are astonishing. Here is a collection of some 50 extraordinary locations, with a thoughtful text by Mark Daly which tells the story of how each of these places was created, how they are used, and what they reveal about the currents of power flowing through the city. <i>Unseen London</i> takes you backstage at some of the capital's great theatres, into the changing rooms of some of our greatest temples of sport, into the heart of the Establishment, the boiler room of the city's infrastructure and behind the scenes at some of the most opulent buildings in the Square Mile.</p>
