On the side of Mount Pellegrino, overlooking Palermo, to the southeast of Mondello beach at above sea level, there are some open grottoes and cavities where bones and tools used for hunting have been found, attesting the presence of humans who lived in them beginning in the Paleolithic and into the Mesolithic. The finds are now conserved in Palermo's Regional Archaeological Museum. Their importance is mainly due to the presence of an extraordinary complex of rock engravings that decorate the walls, constituting a unique case in the panorama of prehistoric cave art. The name Addaura comes from , 'the circuit'.
