Keep Out takes the reader on an exclusive tour of some of England's best kept secrets - those places that the authorities would rather you didn't know anything about or, in some cases, even be aware that they ever existed. That is, until now. Among the locations featured are disused nuclear bunkers, long forgotten tube stations, top secret military bases and a shipwreck that, to this day, is a very real and permanent danger to the coastal residents near to where it rests - an ever present menace that no-one seems to know what to do with. Also featured is a long-abandoned and derelict hospital that found itself a new role that darkly reflected its horrific past. Find yourself a secure location, turn the lights down low and prepare to discover those parts of England where access is forbidden to all but the few. Featuring original and archive photography and maps, Keep Out explores thirty such locations across England, together with a short history of the site as well as details about its present day role. It is a tantalising glimpse behind an iron curtain of secrecy that reveals the fascinating history of these intriguing and important locations.
