It is a natural cavity with perennial ice where the temperature remains around one degree. It is one of the very few places in the Apennines where there is still perennial ice. For centuries, until the mid-twentieth century, the ice was harvested and sold. It is in the Fondi di Jenne area, along the road to Monte Livata. Unfortunately, to descend, one would need to be equipped with ropes.

This place is linked to the figure of the blessed Lorenzo Loricato, a hermit who lived between the 12th and 13th centuries, known for his life of penance and contemplation. After a pilgrimage to Santiago de Compostela and leaving his family, Lorenzo chose to retreat to this area, living in an inhospitable and isolated cave, where he devoted himself to fasting, prayer and penance, feeding on wild herbs. The hermitage consists of some cells dug into the rock, which still today bear witness to the presence of hermits and the desire for spiritual isolation. Over time, the place has become a destination for pilgrimages and of great interest for those who love the spirituality and nature of the Simbruini. The position of the hermitage, overlooking a rocky spur that dominates the Aniene valley, offers a suggestive panorama and an atmosphere of meditation. The hermitage can be reached via hiking trails that cross woods and landscapes typical of the Lazio Apennines.

The Sanctuary of Mentorella is one of the oldest Marian sanctuaries in Europe. Inside the sanctuary there is the cave of San Benedetto, a truly special place: it is a tiny cave which is accessed via a very narrow gap in the rock. Right at the entrance there is a shrine with the bones of the friars. In the sanctuary there is also a small refuge that is always open, with bathrooms and tables.

The Monastery of San Benedetto is an important spiritual place, built almost a thousand years ago to guard the cave where the young Benedetto da Norcia spent his hermit life before dedicating himself to the cenobitic life. Even today, the Sacro Speco emanates the intense and courageous spiritual choice of the young Benedict, inspiring visitors.

The most significant cave is the Sacro Speco, or Holy Cave, located within the Monastery of Saint Benedict. This revered site is where Saint Benedict of Norcia lived as a hermit, profoundly influencing Western monasticism.
