The Underground Great Wall of China is a vast network of tunnels spanning approximately 5,000 kilometers beneath the Chinese landscape. This extensive underground infrastructure was constructed primarily for military purposes, serving as a secure system for storing and transporting intercontinental ballistic missiles (ICBMs). The network represents one of the world's most significant underground military installations, designed to protect strategic assets from potential aerial or nuclear attacks.
The tunnel system forms part of China's strategic nuclear deterrent capabilities, providing hardened storage facilities for its missile arsenal. Built during the Cold War era, these underground passages reflect the military engineering priorities of the period, when nations invested heavily in subterranean defense infrastructure. The network's scale and depth make it a crucial component of China's nuclear weapons storage and transportation system.
Located in Gansu Province at the coordinates 36.3978043, 103.8280742, this facility is part of the broader Underground Great Wall network that extends across multiple provinces. The system demonstrates the strategic importance of underground construction in modern military planning, offering protection against both conventional and nuclear threats while maintaining operational capabilities for China's strategic forces.
