Unearth over 2000 years of history deep below the streets of London. On the surface, London is a buzzing, modern metropolis–but underneath lies a secret, hidden world, all but forgotten by the millions of people above. Secrets of Underground London uncovers 2000 years of subterranean history: a world of ancient caves and perfectly preserved Roman remains; mysterious rivers and gruesome plague pits; impenetrable vaults and top-secret bunkers. As we dig deep, we'll unearth some of the most extraordinary stories of the darkest side of the city.
