The Longyou Caves Mystery: Why Is There Zero Record of the Largest Man-Made Caverns on Earth?

The Longyou Caves Mystery: Why Is There Zero Record of the Largest Man-Made Caverns on Earth? | History for Sleep In 1992, a farmer in China drained his pond after seventeen days of pumping. On June 9th, he saw stairs cut into stone leading down into darkness. He'd found a cave—massive, carved, deliberate. The walls had patterns chiseled into them, pillars held up the ceiling. Then they drained other ponds. Five ponds, five caves underneath. All carved with the same techniques, walls covered in precise 60-degree chisel marks. Ground radar showed more—at least 36 caves total, connected by tunnels. Someone removed a million cubic meters of rock by hand. This episode explores how you hide something this massive, theories about what they were for, and the biggest mystery: how do you erase a thousand workers over decades from history completely?
