Beautiful Limestone Cave

St Michael Cave is a name given to a network of limestone caves, located within the Upper Rock Nature Reserve in Gibraltar, at a height of above 300 meters. The cave was created by rainwater slowly seeping through the limestone rock, turning into a weak carbonic acid which gradually dissolved the rocks, so numerous stalactites and stalagmites in the cave were formed. The largest of the chambers, named the Cathedral Cave, currently serves as an auditorium. It was converted due to the chamber's natural acoustic properties. It is equipped with a concrete stage and has a seating capacity of over 100. The cave is one of Gibraltar's top tourist attractions and is open daily. The cave formations are colourfully lit and visitors can read displays documenting the cave's history.
