The church of S. Francesco al Musone was built in 1796 by a family from Staffolo as a votive offering for the miraculous healings attributed to the water that still flows today from a fountain built in the structure. At this fountain, according to tradition, San Francesco with his faithful friar Egidio quenched their thirst during their preaching along the way towards Ancona in 1210. In the interior walls of the church hung many evidences of a popular devotion that lasts up nowadays.
