Palma was founded as a Roman camp upon the remains of a Talaiotic settlement. The city was subjected to several Vandal raids during the fall of the Western Roman Empire, then reconquered by the Bizantine Empire, then colonised by the Moors (who called it Medina Mayurqa) and, in the 13th century, by James I of Aragon.

The four caves, called Cueva Negra (Cova Negra), Cueva Blanca (Cova Blanca), Cueva de Luis Salvador (Cova de Lluis Salvador) and Cave of the French (Cova dels francesos), are connected to each other. The caves have been formed by the action of rainwater, and some scholars consider their formation could date back to the Miocene.

They host a large underground lake, called Lago Martel (Llac Martel), about 115 m long and 30 m wide. In this lake, considered one of the largest underground lakes in the world, live classical music concerts are offered daily. You can cross the lake by boat at the end of the concert.

The incomparable beauty of these caves is highlighted in an exceptional way by the lighting, projected and realized by the engineer Carles Buïgas.
