Simone Martelli
July 2, 2026, Grotta delle Sirene

The Grotta delle Sirene is a natural cavity carved by the action of the Aniene river. The name derives from local tradition and not from archaeological findings.

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 Pozzo del Merro is a karst sinkhole located in the countryside north of Rome, between the Cornicolani Mountains in Macchia del Barco and Macchia di Gattaceca, in the municipality of Sant'Angelo Romano. According to initial studies by the University of Tor Vergata, the cavity is 392 meters deep, which is the maximum limit the measurements have reached. The probes launched since its discovery have not reached bottom, and the studies continue. This sinkhole has always been known to the locals. In 1890 it appears in the description of a tourist itinerary that leads from Rome to Sant'Angelo Romano, and is described as "a kind of chasm, at the bottom of which extends a small lake and whose very steep sides are covered with trees". https://www.sotterraneidiroma.it/sites/pozzo-del-merro
