These incredible images show locations throughout England's famous old capital as they looked both in history and today. Released by the Museum of London, the composites create a ghostly visual of the city old and new, and include such landmarks as Covent Garden, Tower Bridge and Piccadilly Circus.
The images have been revealed to mark the launch of the Museum’s Streetmuseum 2.0 iPhone app, which is available on iTunes now. The app guides users to sites across London, where hidden histories of the city dramatically appear, illuminated thanks to the institution’s photographic collections.
