This formidable art collection, housed in the picturesque Palazzo di Brera, was amassed (or appropriated) from churches and monasteries by none other than Napoleon. The palace itself was built in 1651 for the Jesuits; in 1776 a wing was allocated to the Accademia di Belle Arti, still in operation today on the lower level. The size of the collection makes for an easy visit with exquisite pieces, including works by major Italian painters from the 13th through the 20th centuries. On show are pieces by Andrea Mantegna, Giovanni Bellini, Piero della Francesca, Donato Bramante, and Caravaggio. The Orto Botanico behind the Pinacoteca is also a peaceful haven from the city buzz.
