A stopping place for visits to one of the largest grottoes in the island - Grotta di Ispinigoli. It houses a large stalactite-stalagmite compound, the tallest in Europe and one of the tallest in the world, measuring some 38 m in total. The grotto also include the so-called Abisso delle Vergini ("Abyss of the Virgins"), a c. 60 m-deep hole leading to a 12 km series of caves connecting Ispingoli to the other grotto of San Giovanni Su Anzu. The name derives from the theory that human sacrifices were held here during the Phoenician rule in this area. Source: http://en.wikipedia.org/wiki/Grotta_di_Ispinigoli
