Underground hospital, bakery and power station hidden in maze beneath sundrenched island Nestled in the south-eastern part of Gibraltar on the Mediterranean coast are a set of World War II tunnels that were home to a hospital, bakery, power station and even a telephone exchange.
For example, the communication tunnels were originally 2.1 metres by 2.1 metres, before later being expanded to 2.4 metres by 2.4 metres.
The main tunnels were dug out to a cross-section of 4.6 metres by 4.6 metres for through traffic routes, with a passing place for vehicles every 91 metres.
The underground tunnel network was also home to a telephone exchange, a power generating station, a water distillation plant, a hospital, a bakery, ammunition magazines and a vehicle maintenance workshop.
The network was large enough to house the entire 16,000-strong garrison in Gibraltar, along with enough food to last them for 16 months.
