China Underground Cities: Secrets of Beijing’s Hidden Bunkers

Imagine standing in a quiet Beijing alley, the hum of the city above fading as you push open a heavy, unmarked door. A narrow staircase spirals downward, inviting you into the depths. This is the entrance to one of China’s most mysterious relics—the Beijing underground city, a sprawling labyrinth of tunnels and chambers built during the Cold War to shield against Soviet threats. Stretching over 85 square kilometers and plunging up to 18 meters deep, this hidden world once housed schools, hospitals, and even a roller skating rink, all designed to withstand nuclear devastation. Today, it’s a half-forgotten maze, part tourist curiosity, part makeshift home to the “Rat Tribe”—low-income workers carving out lives in its cramped, shadowy corridors. Join us as we venture into this subterranean marvel, uncovering the secrets of China’s underground cities and the Chinese secret bunkers that whisper tales of history, survival, and human resilience.

Chinese Underground Cities

A Legacy Forged in Fear

The story of China’s underground cities is deeply rooted in history, but the Beijing underground city—known as Dìxià Chéng—was born from the paranoia of the Cold War. In the 1960s, the Sino-Soviet split fractured communist unity, with ideological rifts deepening into military threats. By 1969, after border clashes like the Zhenbao Island incident, Chairman Mao Zedong feared a Soviet nuclear strike. His response was a colossal underground fortress beneath Beijing, dug by over 300,000 civilians, including schoolchildren, between 1969 and 1979. While ancient wonders like the Han Yangling Mausoleum from the Western Han Dynasty and the 4,300-year-old Houchengzui Stone City with its defensive tunnels show that Chinese secret bunkers have long been part of the nation’s history, the Beijing underground city was a modern marvel, a Cold War necessity cloaked in secrecy.

Building a World Below

Constructed in just a decade, the Beijing underground city is a testament to raw human effort and Cold War engineering. Covering 85 square kilometers, its tunnels snake 8 to 18 meters beneath the city, lined with thick concrete walls and blast-resistant gates. Key features include:

  • Ventilation shafts: Over 2,300 shafts dot the landscape to ensure air circulation.
  • Survival infrastructure: Water wells and storage rooms stocked with grain and oil were designed for long-term sieges.
  • Hidden entrances: Tucked into shops along Qianmen Street or rumored trapdoors in homes, these access points highlight the city’s secretive nature.

As you explore, imagine the echoes of hammers and shovels, the scent of damp earth, and the glow of dim bulbs casting long shadows on murals of Maoist slogans. Chambers reveal:

  • A school with desks frozen in time.
  • A theater with wooden benches awaiting a long-gone audience.
  • A roller skating rink, a surreal touch of leisure in this bunker’s grim purpose.

This underground fortress was built not just for survival but as a symbol of resilience in the face of existential threats.

Life in the Shadows

Today, the Beijing underground city is a relic caught between past and present. Officially closed for renovation since 2008, parts of it have been reclaimed by the “Rat Tribe,” a community of up to a million low-income workers seeking affordable housing in Beijing’s skyrocketing market. These residents have transformed the tunnels into a makeshift city, with:

  • Tiny apartments carved out of former chambers.
  • Communal kitchens and underground shops.
  • A vibrant—if precarious—community beneath Beijing’s bustling streets.

Life here is challenging, with cramped quarters, stale air, and the constant threat of eviction. Yet, as 21-year-old Liu Jian, a resident, shared with NPR, “It’s not much, but it’s home.” His words capture the resilience of those who’ve turned this Cold War artifact into a living, breathing community, a testament to human adaptability in the face of urban challenges.

A Surprising Twist

What’s truly astonishing is how this subterranean fortress, built to withstand apocalypse, has morphed into a refuge for the city’s most vulnerable. The “Rat Tribe” has breathed new life into these forgotten tunnels, creating a vibrant—if precarious—community beneath Beijing’s bustling streets. It’s a stark reminder that history’s grand designs often take unexpected turns, and that even in the darkest corners, life finds a way to thrive.
