Pertosa Caves, Show cave in Pertosa, Italy
Pertosa Caves is a show cave system in southern Italy featuring limestone passages that stretch over 3,000 meters with underground waterways and pools. The formations include mineral-rich walls and create a series of interconnected chambers shaped by ancient water flow.
Prehistoric human settlement at the site is confirmed by archaeological excavations that uncovered tools and primitive objects within the cave passages. These discoveries show that people have visited and sheltered in the cave system for thousands of years.
The cave system is known locally as Grotte dell'Angelo, reflecting the southern Italian tradition of naming natural caverns after Saint Michael the Archangel. This spiritual connection remains part of how the place is understood by people in the region.
Access to the cave is through guided tours that cover around 1,200 meters of the passages, with boat rides on the underground lake near the entrance included. Wear sturdy shoes and be prepared for damp, confined spaces in some sections of the route.
The cave passages served as a filming location for director Dario Argento's 1998 version of The Phantom of the Opera, bringing the underground setting to life on screen. Visitors can walk through the same chambers where dramatic scenes were shot for this horror adaptation.
