The Duomo of Monza (Italian: Duomo di Monza) often known in English as Monza Cathedral is the main religious building of Monza, near Milan, in northern Italy. Unlike most duomos it is not in fact a cathedral, as Monza has always been part of the Diocese of Milan, but is in the charge of an archpriest who has the right to certain episcopal vestments including the mitre and the ring.
