From an analysis of ancient documents, on the other hand, it seems more probable that the urban nucleus was born from a village formed around the parish church of Santa Vittoria, between the 9th and 10th centuries, and placed along the Via Francigena, an itinerary that served as a link between Rome and central Europe, especially France.
The cathedral is a Romanesque basilica and historically belonging to the Benedictine order. It is called the Holy Sepulcher because it holds a stone stained with blood which is said to come from the Holy Sepulcher in Jerusalem. The relic is kept inside a Romanesque-style crypt, one of the most important and characteristic in Italy due to its ancient origins (10th-11th century)
