Accademia di Belle Arti di Brera
This beautiful seventeenth-century building is still a functioning university, but thanks to its significant inventory of cultural loot, it also operates as a museum, known as the Pinacoteca di Brera. The site started as a convent but opened as a museum in 1809. Nowadays, it’s home to Milan’s primary collection of paintings, with pieces you’ll probably recognize from your art history textbook—Raphael’s Marriage of the Virgin, Caravaggio’s Supper at Emmaus—as well as more modern works by artists like Modigliani. After browsing the galleries, take a stroll through the on-site botanical gardens.
