Beneath Beijing lies a secret. It’s a network of tunnels a city beneath a city. This is the Underground City also known as the Underground Great Wall. Built during the Cold War it was designed to protect Beijing’s population from a nuclear attack.
Imagine a time of intense tension between China and the Soviet Union. Chairman Mao Zedong fearing a devastating war ordered the construction of this vast complex. From 1969 to 1979 hundreds of thousands of people mostly volunteers dug this incredible network of tunnels. They used centuries-old city walls and gates as building materials. Think of the sheer scale. Eighty-five square kilometers of tunnels. Deep underground.
The Underground City wasn’t just a bomb shelter. It was a self-sufficient city. It had restaurants clinics schools even a roller skating rink. There were grain and oil warehouses and even a mushroom farm. Everything was designed to ensure survival. Elaborate ventilation systems protected against poison gas. Gas- and water-proof hatches and thick concrete gates shielded the tunnels from attack.
The government claimed it could hold all six million of Beijing’s inhabitants. No one knows for sure the true extent of the network. Some say the tunnels connect Beijing’s landmarks and government buildings. Perhaps they even reach military bases. Rumor has it that each home had a secret trapdoor leading to the tunnels.
The Underground City was officially opened to the public in 2000. Tours took visitors through a small section. They saw signposts to major landmarks chambers labeled with their original functions faded slogans like “Accumulate Grain” and “For the People Prepare for War Prepare for Famine”. They even saw a silk factory operating in a former staff meeting room. They could buy souvenirs at a shop run by the state-owned Qianmen Arts and Crafts Center.
The Underground City is currently closed for renovations. It is a fascinating relic of the Cold War. It’s a reminder of China’s history and ingenuity. It’s a ghost city waiting to be explored. A place where history whispers from the shadows. When you walk these streets remember the people who built this amazing place. Remember their hope. Their fear. Remember their resilience.
