The ecclesiastical region of Lombardy currently includes ten dioceses: Bergamo, Brescia, Como, Crema, Cremona, Lodi, Mantua, Milan, Pavia, Vigevano. They are the "remnant" of a grandiose ancient metropolis: nineteen suffragan dioceses were present in the provincial council of Milan in 451. In addition to those indicated above: Albenga, Aosta, Asti, Brescello, Coira, Genoa, Ivrea, Novara, Piacenza, Reggio Emilia, Turin, Tortona, Vercelli. Although scaled down over the centuries, it is among the largest ecclesiastical regions of Italy and certainly the most populous and rich in structures and people. Leaving the individual dioceses their prospectus, it is worth noting that the ecclesiastical region extends over 22,699 km2, from Ticino to Lake Garda, from Valtellina to the Po, including the whole civil region and the impressive numbers shown on the previous page characterize marked differences the dioceses. They range from the diocese of Brescia, which has an area of 4538 km2 to just 276 in Crema.
