Founded by Milan's patron saint and the model for Lombard Romanesque architecture.
IGBy Ivanka García Mancebo · Civitatis travel specialist
The Basilica di Sant'Ambrogio is one of Milan's most important and significant churches — and one of the great monuments of northern Italy. Consecrated in 387 AD by Saint Ambrose himself, it was rebuilt in the Lombard Romanesque style in the 11th century, becoming the architectural model for churches across northern Italy for generations.

History & significance
Founded by Saint Ambrose, the great 4th-century bishop and patron saint of Milan, the basilica has been at the heart of the city's religious life for over 1,600 years. Its 11th-century rebuild set the template for the Lombard Romanesque — the arcaded atrium, twin bell towers and brick facade were copied across the region.
It remains a working church and a place of pilgrimage, as well as one of Milan's essential monuments.
What to see inside
Beyond the architecture, several treasures reward a closer look.
Early Christian
Stilicho's Sarcophagus
A richly carved 4th-century Roman sarcophagus beneath the pulpit.
The relics
Crypt of three saints
The crypt holds the remains of Saint Ambrose with Saints Gervasius and Protasius.
Golden mosaic
Oratory of San Vittore
The Oratory of San Vittore in Ciel d'Oro, with its dazzling 5th-century golden mosaic ceiling.
The approach
The atrium
A serene arcaded courtyard containing early Christian and medieval carvings.
A peculiar temple
Although the basilica was badly damaged during the Second World War, both its exterior and its interior have been beautifully restored and preserved. The two mismatched bell towers and the arcaded atrium give it a character quite unlike any other church in the city.
In our opinion it's one of the most interesting churches to visit in Milan — and, being free to enter, an easy one to fit into any itinerary.
