This place is wonderful, if you come to Tivoli you must visit it! Some advice: - It's better if you come in the morning so there will be more light. After a certain time in the afternoon, I believe that not much light will reach the lower part of the park. - It's better to bring hiking shoes and not flip-flops or smooth shoes because some parts of the trail are tricky.

A unique historical and spiritual complex, carved into the rock along the walls of the Aniene valley. These hermitages are linked to the figure of Saint Benedict of Norcia, who stayed there briefly in 503. During his time at San Cosimato, it is said that the monks attempted to poison him, but the vessel containing the poison miraculously shattered when Benedict blessed it with the sign of the cross. The caves, accessible via a staircase carved into the rock, include a rock chapel dedicated to Saint Michael the Archangel, rich in frescoes, and an ossuary. The convent above, built later by Benedictine monks, was dedicated to the saintly doctors Cosma and Damiano. This place combines history, art and spirituality in a suggestive naturalistic context.

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.
