It was built three centuries before the year one thousand. It served as a refuge for the many wayfarers who passed through those wild places. It was an era in which dangers were not lacking, including those deriving from the attacks of the bandits who were stationed in the mountains. Attached to the ancient hermitage, there was a chapel which over the centuries was transformed into a rustic building for the use of the peasants who lived there, after the complex lost its primary function.
Equipped with a beautiful crenellated tower (now destroyed). The entire building is in a complete state of abandonment. Legend has it that it was built by the French monk Alluciem, who with two other companions Justis and Barontes, left the monastery of Cluny, from which it had taken its name from the order to which they belonged; Cluniac. The three monks moved to these mountains in three different places. Each of them built a chapel and a hermitage.
These places (San Baronto, San Giusto al Pinone and Sant'Alluccio) took and still have the name of the three French friars. Legend has it that the three friars passed the ladle from one place to another to wall up the three buildings. In these buildings the pilgrims were not only refreshed, but if they needed it they were also physically treated.
