The cistern was built by the architects of the II Praetorian Legion to ensure the necessary water supply for the camp and surrounding dwellings. They could store 10,000 m³ of drinking water. However, their importance is not only due to this, but also because they are still perfectly functional today, being fed by Roman-era pipelines that receive water from springs located along the sides of Lake Albano.

The small iron door framed by the peperino architrave goes almost unnoticed but if it is found open it allows access to the entrance tunnel of this work of hydraulic engineering from the Roman era. The emissary of Lake Albano was presumably excavated at the beginning of the 4th century BC to regulate the level of the lake and, both for the technical difficulties encountered in the excavation and resolved with limited means and for the functionality that remained intact until the 1960s of the last century, it can be considered one of the most important hydraulic testimonies of our past. Some historical sources also speak of the emissary: Titus Livius links its construction to the final results of the war between Rome and Veii.

Mysterious Caves of Palazzolo, a short distance from Rocca di Papa and Albano, with a balcony view of Lake Castel Gandolfo. Close to a medieval convent, these cavities were used as stone mines in the Roman and medieval periods but some scholars hypothesize that they also functioned as prisons in unspecified periods. The frequenting of the area by brigand gangs in the eighteenth and nineteenth centuries is documented by reliable historical sources. In recent times, however, these mirrors have apparently hosted satanic masses and other similar rites.

the Caves can be visited all year round, along a path that runs along the upper part of Lake Albano. The path is traveled by many people on mountain bikes and on foot. Taking the path of the Devil keeping the path to the right, then straight. Unfortunately, beyond the caves the collapse of a wall no longer allows, as years before, to take the route of the lakes, one is forced to go back.
