Between the 11th and 12th centuries the church was rebuilt in Romanesque style, becoming a model for Lombard architecture. The bombings of 1943 damaged the portico, but restorations in the 1950s restored it to its former glory. Here are the key moments:

Created between 824 and 859, it is covered with gold and silver panels depicting scenes from the life of Christ and Saint Ambrose. Above the altar stands the 9th-century Ciborium, supported by four Roman porphyry columns and decorated with 10th-century stuccoes. Don’t miss the Chapel of San Vittore in Ciel d’Oro, a small 5th-century Early Christian building with mosaics portraying Ambrose among the martyrs.

Legends and Curiosities: The Devil and the Serpent

Outside the basilica, near the entrance, stands the Devil’s Column: it has two holes that, according to tradition, were made by the devil’s horns during a fight with St. Ambrose. In reality, the holes were used for the coronation of German emperors. Inside, on a column, sits a 10th-century bronze serpent, a gift from Emperor Basil II.

When to Go

The best time? Late afternoon, around 4:30 PM, when the low light filters through the windows of the facade and illuminates the gold of the altar, creating an almost mystical atmosphere. If you prefer tranquility, avoid the central hours and Saturday afternoons, when there is more foot traffic. In winter, with the Milanese fog, the basilica seems even more shrouded in mystery. Sunday afternoons are open only from 3 to 5 PM, but it is often quieter. If you are in Milan on December 7, don’t miss the celebration of the patron saint.
