Basilica of Sant'Ambrogio

The Story

The Basilica of Sant'Ambrogio is one of the most venerable churches of Milan, Italy, founded by St. Ambrose himself between 379 and 386 in an area where martyrs of the Roman persecutions lay buried. First called the Basilica Martyrum, it received the bishop's own body at his death in 397, and has borne his name ever since. Ambrose, a Roman governor acclaimed bishop of Milan by popular demand in 374, became one of the towering figures of the early Church: defender of orthodoxy against Arianism, father of Western hymnody, fearless before emperors, and the preacher whose words helped lead Augustine to baptism at Easter of 387. He is honored as one of the four great Latin Doctors of the Church. In the crypt beneath the high altar, the relics of St. Ambrose rest beside those of the early martyrs Gervasius and Protasius, whose remains Ambrose himself discovered and translated to the church in 386. Above them stands the celebrated 9th-century golden altar of Vuolvinio, a masterpiece of Carolingian art. Rebuilt in the 11th and 12th centuries, the basilica is a model of Lombard Romanesque architecture with its atrium and twin bell towers. It remains a heart of Milanese Catholic life, where the ancient Ambrosian rite recalls the bishop whose memory still shapes his city; his feast on December 7 is Milan's great patronal celebration.

Church Recognition

Sant'Ambrogio is a minor basilica of the Archdiocese of Milan and the historic shrine of St. Ambrose, Doctor of the Church, whose relics rest in its crypt with the martyrs Gervasius and Protasius; the Ambrosian liturgical rite preserves his legacy with the Church's approval.

Catholic Teaching

The basilica witnesses to the veneration of relics from the earliest centuries (CCC 1674), a practice St. Ambrose himself fostered, and to the office of bishops as teachers and shepherds of the faith (CCC 888-896), exemplified in one of the four great Latin Doctors of the Church.
