The cave was originally believed to be bottomless, leading to the legend that the Rock of Gibraltar was connected to Africa by a subterranean tunnel under the Strait.

Saint Michael's Cave is a network of limestone chambers located within the Upper Rock Nature Reserve in Gibraltar. The main chamber, Cathedral Cave, has been repurposed as an auditorium featuring a multi-colored LED light show synchronized with music. During World War II, the cave was prepared for use as an emergency military hospital, though it was never utilized for that purpose. Excavations have revealed evidence of prehistoric human occupation, including Neolithic artifacts. The cave system is formed by the erosion of limestone by rainwater, resulting in extensive stalactite and stalagmite formations. Visitors navigate the site via paved walkways and viewing platforms. The site is part of the Gibraltar Nature Reserve and sits at an elevation of over 300 meters above sea level.

Do not attempt to feed or approach the Barbary macaques that frequently gather near the entrance.
Do not touch the stalactites or stalagmites, as natural oils from human skin can permanently damage their growth and color.
