The Abandoned City That Still Exists Beneath Central London

Beneath the pavements of central London lies not one buried city, but several, stacked on top of one another across two thousand years. Roman temples, medieval rivers, Victorian sewers, abandoned Tube stations, secret wartime bunkers, and Cold War telephone exchanges all survive intact beneath the modern street. This documentary traces how London never demolished its old cities. It simply built new ones on top of them, sealing each previous version in the dark.
