The 816 Underground Nuclear Project, located in the Fuling District of Chongqing, is one of China's most intriguing historical sites. Once a top-secret military project during the Cold War, it is now a 4A-rated national tourist attraction. This massive underground complex was designed to produce weapons-grade plutonium, marking China's first independent attempt at building a nuclear reactor without Soviet assistance.
The project was initiated in 1966, authorized by Chinese Premier Zhou Enlai, and construction began the following year. Over 60,000 soldiers and workers toiled for 17 years to carve out this colossal underground facility from the mountains. The complex was designed to withstand the impact of multiple nuclear bombs and featured a network of tunnels and chambers extending over 20 kilometers. It included a reactor hall large enough to accommodate a football field and a control room with advanced equipment. However, the project was never completed due to changes in the geopolitical landscape and was eventually terminated in 1984.
The 816 Project was declassified and opened to the public in 2010. Today, visitors can explore the eerie remnants of this once-secret facility. The site offers a rare glimpse into China's Cold War history and the lengths to which the country went to ensure its national security. The reactor hall, control room, and other areas are now open for tours, allowing visitors to step into a world that was once shrouded in secrecy.
The 816 Underground Nuclear Project is not only a testament to China's technological capabilities but also a symbol of the country's determination to protect its sovereignty. It stands as a reminder of a different era, when the threat of nuclear conflict loomed large and nations went to great lengths to prepare for potential confrontations. Now, it serves as a unique tourist destination, offering a chilling yet fascinating look into the past.
