Santa Maria presso San Celso is a late 15th-century church and sanctuary south of Milan's historic centre. It is worth the detour for its rich Renaissance and Baroque decoration, with work by Milanese artists in a calmer setting than the city's headline churches.
The church rewards a slower look: chapels, sculpture, and painted detail build up into a strong sense of local devotion rather than a single showpiece moment. Pair it with nearby Porta Ticinese or the Navigli if you are exploring this side of the city.
