Located more than 300 meters above sea level on the western slope of the famous Rock of Gibraltar, it is the largest of more than a hundred caves known in this region. This incredibly popular site attracts up to a million tourists annually, making it a must-see when visiting the city of Gibraltar.

Inside, the cave is striking in its scale and natural beauty. The vast chambers are decorated with numerous stalactites and stalagmites, formed over thousands of years as a result of rainwater slowly seeping through the limestone. The cave consists of several levels connected by passages up to 45 meters deep, and its extensive tunnel system once even gave rise to legends of a secret passage under the strait all the way to Africa.
Today, the cave serves not only as a natural wonder but also as a unique cultural venue. Its main chamber, known as the "Cathedral Cave," has been converted into an extraordinary concert hall due to its exceptional natural acoustic properties. Concerts, theatrical performances, and other events are regularly held here, offering visitors a truly unforgettable experience.
