10 Darkest Archaeological Discoveries Found Underground

Beneath deserts, churches, mountains, and modern cities lie ancient places built for gods, survival, sacrifice, and the dead. In this documentary, we descend into ten of the most terrifying underground sites ever discovered. Beneath Alexandria, the Catacombs of Kom el Shoqafa preserve an impossible fusion of Egyptian, Greek, and Roman religion. At Saqqara, enormous granite sarcophagi were transported hundreds of miles and lowered into tunnels to bury sacred Apis bulls. In Peru, the underground galleries of Chavín de Huántar used darkness, water, sound, and psychoactive rituals to overwhelm the human mind. In Cappadocia, the inhabitants of Derinkuyu constructed an underground fortress capable of hiding thousands of people beneath invading armies. We also investigate the Plutonium of Hierapolis, where an invisible lake of carbon dioxide created a real gateway to death; Malta’s Ħal Saflieni Hypogeum and its mysterious Oracle Chamber; the sealed Zapotec underworld beneath Mitla; the controversial Homo naledi remains inside the Dinaledi Chamber; and the human bones fused into the floor of Midnight Terror Cave. Finally, we travel to China, where the unopened tomb of Qin Shi Huang may still contain rivers of mercury, fragile treasures, and the untouched burial chamber of the first emperor. These places were not legends. They were real structures created by ancient people—and many of their deepest chambers remain unexplored.
