For thousands of years, when the world above got too dangerous, humans didn't build higher. They built entire cities beneath the earth. This is the story of three of them — Derinkuyu in Turkey, Nushabad in Iran, and Naours in France — built by peoples who never met, on three continents, out of three completely different kinds of rock, for the exact same reason. We dig into how they carved 20,000-person cities by hand, how the disguised entrances and rolling stone doors worked, and why "disappearing" was one of the smartest survival strategies our ancestors ever invented.

And tell me: if raiders were coming and you had one hour, would you actually climb down into the dark — or take your chances above ground?
