Bocca Lorenza (cave)

The Bocca Lorenza cave is a natural cavity that enters the bowels of the Summano and descends into a series of rooms located at increasing depths.Since the early years of the twentieth century, excavations have been carried out which have brought to light numerous finds dating back mainly to prehistoric times, which testify to its use as a domestic shelter, tomb and place of worship.The interior of the cave can be freely visited and equipped with cables (perpetually wet due to humidity), but experience and adequate equipment are still required: a headlamp and helmet are essential. For everyone else, it's best to stop at the lobby. The cave is very humid and dark, with a slippery bottom and a constant temperature of around 13 degrees.it.wikipedia.org/wiki/Bocca_Lorenza
