10,000 Miles of Tunnels: The Hidden World Beneath Civilization | History for Sleep

Beneath our feet lies another world — a vast network of ancient tunnels, hidden cities, and secret chambers that stretch for 10,000 miles beneath civilization. From Derinkuyu in Turkey to Teotihuacan’s mercury rivers, from Chavín de Huántar’s resonant labyrinths to the Longyou Caves of China, every layer of Earth hides a forgotten chapter of human history.

Were these tunnels built for survival, for worship, or to hide something humanity was never meant to see?
This documentary uncovers the hidden world beneath civilization — the underworld of myth and stone where science, archaeology, and legend collide.
