Stephen Smith quite literally delves into the unknown country underneath ploughed fields, clifftops and market towns. UNDERGROUND ENGLAND will explore rudimentary earth dwellings and hidden Cold War cities; sulphurous natural springs and manmade underground waterways; priest holes and subterranean nooks created with more sinister purposes in mind. The author visits the endless military tunnels built below Chatham since the Napoleonic Wars; and the secret labyrinth quarried out under Liverpool by a religious eccentric. He gets into tight spots with speleologists, and gamely ventures down haunted tunnels and into the mythical resting-places of English kings. A fascinating and eye-opening exploration of the world that lies beneath our feet.
