Grotta del Farneto (Farneto Cave) was discovered in 1871 by Francesco Orsoni. It became known in the 1960s when Luigi Fantini discovered Copper Age graves in a natural shelter in front of the cave. The graves were excavated and the findings are today exhibited in the Museo Archeologico di Bologna (Archaeological Museum of Bologna). The outcrop had been destabilized by quarry works and collapsed finally, the cave was blocked by the landslide. The landslide was removed and the cave entrance stabilized, the cave was reopened for tours in 2008.
The gypsum of this area was formed about six million years ago in the Messinian period. At this time the Straits of Gibraltar closed up and the Mediterranean sea became a salt desert. The Bolognese Gessi, the gypsum of Bologna, was deposited in the sounding-depths contouring the just emerged Apennines. The rock is rather young and the karstification too, it started two million years ago in the Pliocene. The gypsum was locally called selenite (moon stone), due to its pale white colour. This stone was used for buildings in the area and in the close city of Bologna, which then was called moon city for its shine during the day when the sun was grazing. The term selenite is still used, but it describes a certain sort of gypsum crystals, not the common rock. Numerous quarries, where the gypsum was quarried can be seen in the area. After being closed for centuries, the quarry walls look like natural cliffs.
