The vast area behind the settlement of Sciacca, which culminates in Monte Kronio, may be the site of an ancient volcano, which even today shows some activity, however slight, through the emission of sulphur vapours.

Because of the high temperature, people once spent time in the cave, which was created by Daedalus in the territory of the Sicans according to legend, as a cure for arthritis rheumatism, gout, and sciatica.

Seats, benches and drilled holes into which effected limbs must have been inserted were carved in the interior walls.

Following a survey carried out in 1880 by professor Silvestro Zinno on behalf of the comunale council of Sciacca, the comune proposed to turn this into a spa.

In 2012 Copper Age jars dating from the fourth millennium BC were found in a cave on Monte Kronio.
