San Maurizio al Monastero Maggiore

The church was built from 1503 for the Monastero Maggiore, Milan's most important Benedictine convent. A wall divides it in two: in front, the nave for the public, and behind, the hall where cloistered nuns followed Mass unseen.

Every wall and vault is covered in 16th-century frescoes, many by Bernardino Luini and his workshop, showing the Passion, saints and landscapes. The nuns' hall has an organ from 1554 that is still played. Next door, the Archaeological Museum preserves a tower from the Roman walls.
