Exploring Beijing’s Underground City: A Cold War Relic Built for Nuclear War

Beneath the bustling streets of Beijing lies a vast network of tunnels known as the Underground City, a stark reminder of Cold War tensions. Constructed between 1969 and 1979, this subterranean complex was designed to shelter millions of residents from potential nuclear attack, primarily during the Sino-Soviet border conflicts.

According to historical records, the Underground City spans approximately 85 square kilometers (33 square miles) and lies 8 to 18 meters (26 to 59 feet) below the surface. At its peak, the complex featured around 90 entrances, cleverly concealed within shops along Qianmen Street and other central districts. These hidden access points allowed civilians to seek refuge quickly in the event of an emergency.

The facility was not merely a shelter; it included essential infrastructure to support prolonged underground habitation. Historical accounts describe the presence of schools, hospitals, factories, and even markets within the tunnel system, aiming to maintain a semblance of normal life during extended stays. Ventilation shafts and water systems were integrated to ensure basic habitability.

Following its construction, the Underground City was opened to the public for tours in 2000, offering visitors a glimpse into this unique chapter of Beijing’s history. Described by some as “dark, damp, and genuinely eerie,” the tours provided insight into the scale and purpose of the Cold War-era project. However, the site has been closed for renovation since at least February 2008, with many original entrances subsequently demolished or blocked off due to urban development.

Today, only a few entrances remain accessible, including locations such as 62 West Damochang Street in Qianmen, the Qianmen Carpet Factory at 44 Xingfu Dajie in Chongwen District, and 18 Dashilan Jie in Qianmen. These remnants serve as tangible links to a period when the threat of nuclear conflict shaped urban planning and civil defense strategies in China’s capital.

The Underground City stands as a testament to the lengths cities will move to protect their populations in the face of existential threats. While no longer active as a functional shelter, its preservation offers valuable historical perspective on Cold War civil defense preparations and the resilience of urban infrastructure.
