 It is unclear if the present structure was standing at the time of Pope Leo IX’s visit in 1053, but the diocese records clearly show that the designation of Santa Maria dell'Assunta was elevated to a cathedral in 1061 and was presided over a Bishop by the name of Peter.On April 7, 1751 relics of Saint Gaudentius (San Gaudenzio) were transported by two Capuchin friars from the catacombs of St. Priscilla to the Cathedral in Guardialfiera.These were given to Mons.
