In 1940 Gibraltar was surrounded, Churchill expected an attack, and the response was to dig. The wartime tunnelling created a network capable of housing a garrison of 16,000 men with the supplies to last them a siege — a self-contained underground city with its own power station, hospital, bakery and water supply.

Much of the network is still military and closed. The section open to visitors gives a clear sense of the scale, and of how seriously invasion was expected.
