Discover more about Great Siege Tunnels

The Great Siege Tunnels, also known as the Upper Galleries, represent a remarkable feat of military engineering born out of necessity during the Great Siege of Gibraltar. Facing a combined Spanish and French force attempting to recapture Gibraltar, the British military constructed these tunnels to create protected passages and gun positions within the Rock of Gibraltar. Excavation began in May 1782, with workers relying on manual labor, picks, chisels, iron wedges, and gunpowder to tunnel through the dense limestone. The tunnels stretch for several kilometers, revealing the ingenuity and determination of the soldiers and civilians involved. Ventilation issues prompted engineers to cut openings along the cliff face, which then became gun ports, enabling defenders to target enemy lines. Cannons were mounted in these tunnels, allowing the British to fire down at the enemy forces. Inside, visitors can explore chambers and passageways, view displays of weapons and equipment, and learn about the conditions faced by the defenders. The tunnels were expanded after the siege and reused during World War II. The Great Siege Tunnels offer breathtaking views of the surrounding area, including the Strait of Gibraltar and the Mediterranean Sea.
