Basilica di San Vincenzo

The basilica was re-consecrated by Aribert, archbishop of Milan, who at the time was likely the hereditary tenant of the edifice: this is testified by the presence of graffiti under the apse's frescoes, which mention the death of his father, brother and nephew.

Other sections went lost during the French occupation in the early 19th century, when they were considered of no artistic interest and sold to private collectors.

The crypt has two halls with cross vaults, above which, originally, were two ambons: today only part of the left one remains, with a marble eagle which once supported the lectern.

The fourth panel features St Aribert offering a model of the church to God: the upper part of this scene is now at the Pinacoteca Ambrosiana of Milan.

Its plan is inspired by that of the 9th century Santa Maria presso San Satiro in Milan, although in a simplified form: a cruciform shape with a square hall limited by four isolated columns and four perpendicular arches, and four semicircular niches.

The western niche opens to the interior, from which stairs lead to the matronei (tribunes in the upper floor), which are not present in San Satiro.
