A few steps from the central streets of Ancona, one of the most beautiful and unique places in Italy – at the base of the white cliffs of Conero, is Passetto, a gorgeous rocky beach that extends for about a kilometer. Rather surprisingly there are also more than 100 caves tucked into the rocky shore here.

These caves were excavated in the late 1800s and dug deep into the cliff face, using only hand chisels, and provided shelter for small fishing boats and related on-board equipment.
