Tunnels of Gibraltar, Military tunnel network in Gibraltar, United Kingdom.
The tunnel system beneath the Rock extends for over 30 kilometers through interconnected passages carved into limestone. The network includes command centers, storage chambers, and various rooms designed for military operations and defense.
British forces began expanding the tunnel system in the 1700s, but greatly enlarged it during World War II for military purposes. Thousands of workers blasted through the rock to create command centers, ammunition storage, and living quarters.
The displays show military artifacts and wartime photographs that tell the story of soldiers living and working deep beneath the rock.
Guided tours provide access to specific sections with professional guides explaining the engineering and strategy. Visitors should wear comfortable shoes and be prepared for uneven surfaces and cool underground temperatures.
Sections of the tunnel system now house modern data centers storing information for global financial institutions with advanced security. The underground location provides natural protection that benefits modern data storage needs.
