Eremo di Grottafucile, Medieval hermitage in Monte Revellone, Italy.

The Grottafucile hermitage is a monastic settlement carved into natural caves, featuring individual living spaces, a shared courtyard, and a water well within the mountain. It sits at roughly 380 meters above sea level on Monte Revellone and can be reached by walking trails through the surrounding regional park.

Silvestro Guzzolini, bishop of Osimo in conflict with his diocese, withdrew in 1227 to a cave on Monte Revellone donated by Corrado di Rovellone. Followers joined him, and in 1228 Pope Gregory IX sent two Dominican friars to urge affiliation with the Benedictines. Around 1231, as the community grew, Silvestro moved to Montefano and began a small Gothic church, Santa Maria a Grottafucile, while the hermitage was enlarged into a monastery in 1265.

The site represents a retreat for solitary religious life, showing how monks chose to live apart from larger communities in remote locations. Visitors today can see how the natural caves were adapted into spaces for prayer and contemplation.

Wear sturdy hiking shoes and bring plenty of water, as the trails leading to the caves cross rough mountain terrain. It helps to check trail markers and parking locations before visiting, since access depends entirely on walking through the nature reserve.

The 1844 visit by Filippo Bigioli left a written account of the hermitage's condition. A quarry opened at the base of the hermitage and the later Gola della Rossa tunnel threatened its stability, until the ministry halted the works in the 1970s to protect the remains.
