According to tradition, until the fourteenth century, the top of this mount was sharp. The shepherds would have flattened the top and used the rock to build a square and a chapel dedicated to the Virgin Mary, which was used as a shelter as well from bears and bad weather. The first document, attesting the existence of a church on top of the mountain, is a deed of sale dated 26th July 1368. However, the popularity of the place dates back to 1630, when the plague was raging. The faithfuls went in procession to the Madonna del Bisbino and made a vow that if the communities had been preserved from the infection they would have repeated the pilgrimage every first Wednesday of the month for an entire year. Fortunately, the communities were saved from the epidemic and the popularity of the church grew considerably, so that pilgrims became more and more numerous.
