The Grotta di Ispinigoli is a karstic cave in the Supramonte massif, near Dorgali, Sardinia, Italy.
One of the largest grottoes in the island, houses a large stalactite-stalagmite compound: that huge column you can easily spot in the pictures. It's the tallest in Europe and one of the tallest in the world, measuring 38 m in total. The grotto also include the so-called Abisso delle Vergini ("Abyss of the Virgins"), a 60 m-deep hole leading to a 12 km series of cafes connecting Ispingoli to many other caves of this part of the island, creating a huge underground labirinth which is still partially unexplored. The name derives from the theory that human sacrifices were held here during the Phoenician rule in this area.
