The cave was discovered by the cave explorer and Jesuit, Father Fureddu, in 1957 and was opened to the public in 2003. It ranks as one of the most beautiful and most important caves of the island.

The guided tour leads the visitor through three branches. The cave is of utmost importance not only because of its enormous variety of concretions, but also because of its siphon (or drain) which connects the cave with the open sea ,and which was used by the monk seal to enter the cave.
