On the peak of Jinzi Mountain in Fuling, China, a single chimney stands sentinel over the adjacent Wu River. The chimney has been idle since it was built decades ago. 15 years ago, the local government announced that inside the hollowed-out mountain lay the remnants of what was once one of China’s most ambitious military infrastructure projects: the top-secret 816 nuclear plant, a remnant of the 1960s. At the time, China was trying to build a nuclear reactor that could produce weapons-grade plutonium without Soviet involvement. Officials made the unusual decision to place the reactor underground, complicating an already challenging engineering process. The result: what is said to be the world’s largest artificial cave. In 2010 it was revived for tourism. Now, after a year of renovations, visitors — including foreigners — can now see about one-third of the cave, which contains nearly 13 miles of tunnel roads. @gillessabrie took this photo of one of the tunnels, lit by LEDs.
