The diocese of Milan is one of the largest in the world and is the only bishopric in the western Church to maintain its own Ambrosian liturgical rite, originally introduced by Saint Ambrose, the Patron Saint of the city. This extensive and important diocese includes some Catholic Churches of major historical and artistic interest.
The first stop on this religious and artistic itinerary is the iconic symbol of Milano, and possibly the most important Gothic building in Italy, the Duomo. The second is the first Western church built in the shape of a Latin cross, San Nazaro, followed by the paleo-Christian basilica of San Lorenzo Maggiore.
At a short distance, we come across two of the most ancient churches in Milano, Sant'Eustorgio and Sant’Ambrogio. The latter is the most important example of Romanesque architecture in Lombardy. The itinerary then leads to two Renaissance jewels: Santa Maria delle Grazie, a UNESCO World Heritage Site, and San Maurizio al Monastero Maggiore. The itinerary ends up with San Marco - the cradle of the Augustinians, San Simpliciano - one of the basilicas founded by St. Amborse, and the late-Renaissance church, Santa Maria della Passione.
