Peel back the layers under a London street and you'll discover a haunting, dreamlike world of hand-laid brick sewers, forgotten tube stations, World War II evacuation shelters, secret government bunkers, and tunnel boring machines laying new sewer, communication, and transport grids. Bradley L. Garrett has worked with explorers of subterranean London to collect an astonishing array of images documenting forbidden infiltrations into the secret bowels of the city. This book takes readers through progressively deeper levels of historical London architecture below the streets. Beautifully designed to allow for detailed viewing and featuring bespoke map illustrations by artist Stephen Walter, this unique book takes readers to locations few dare to go, and even fewer succeed in accessing.
