Located 20 meters above sea level, it is a prehistoric cave not of natural origin but dug by man. Dedicated to the cult of pagan divinities, as evidenced by the discovery of 30 tables with inscriptions in Greek and Latin. This prestigious cave can be reached by land; it looks like a sort of “altar on the sea” where not only indigenous peoples, but also pilgrims or passing sailors, invoked the help and protection of the gods during their sea crossings.
