London Under is an atmospheric, imaginative introduction to everything that goes on under London, from original springs and streams and Roman amphitheatres to Victorian sewers, gang hideouts and modern Underground stations. This book tunnels down through the geological layers, meeting the creatures, both real and fictional, that dwell in the darkness - rats and eels, monsters and ghosts. From the Anglo-Saxon graves under St Paul's, to the hydraulic device in Kensal Green cemetery which lowered bodies into the catacombs below, to the fossils uncovered when the Victoria Line was built and the gold bars within the Bank of England's vaults, London Under takes you into a hidden world, beneath our feet.
