Gibraltar has always been of the utmost strategic importance, but with the entry of Italy into World War II and a powerful Germany already dominating Europe, that importance grew. These tunnels, created by the Royal Engineers and the Canadian Army, were the answer to the ever-growing problem of storage, space and siege accommodation. The entire 16,000-strong garrison could be housed here, along with enough food to survive for 16 months. The entire tunnel network inside the Rock is about 34 miles, 55 kilometers.

St Michael’s Cave was long believed to be bottomless. This probably gave birth to the story that the Rock of Gibraltar was linked to Africa by a subterranean passage under the Strait of Gibraltar. The famous macaques were said to have come to Gibraltar through this subterranean passage. Pomponious Mela, one of the earliest geographers who lived about the beginning of the Christian era, spoke about the cave in his writings. It was at one time believed that in 1704 Spanish troops spent a night in the cave after climbing the precipitous east face of the Rock. Another story about the cave recounts how a Colonel Mitchell and another officer were said to have descended into the cave at some unspecified date before 1840 and were never seen again. During WWII the cave was prepared as an emergency hospital, but was never used as such. The cave is open to visitors and makes a unique auditorium for concerts, ballet and drama. It has been in use as a theatre since the early sixties with capacity for 600 persons. At some period during the history of this cave, part of a stalagmite became too heavy on one side and fell, possibly thousands of years ago. It now lies on its side at the far end of the main chamber, cemented through the years by nature to the floor of the cave. In 1972 a slice was cut off from the top end which revealed the interior structure of the stalagmite in a most dramatic fashion. ‘The Awakening' at St Michael’s Cave An immersive light and sound installation expressing layers upon layers of history fused with the Rock. These ancient clocks now lay dormant. The Awakening illuminates these sculptures of time and reawakens their hidden story. As you journey through the cave system you will encounter these giant ancient clocks brought back to life, vast hidden forms and towering flowstones that once again are in full motion. The experience culminates within the main cavern in a 360-degree projection and light spectacle.’ The awakening show takes place every 7 minutes.
