At the end of 18th century, the empress Maria Teresa of Austria established that Palazzo Brera, previously owned by religious institutions, would become one of the most advanced cultural institutions of the city. The art collection within the Pinacoteca di Brera has expanded over the years and the museum now holds some of the most well-known portraits and paintings by 15th and 16th Century masters including Raffaello Sanzio, Andrea Mantegna, Giovanni Bellini and Piero della Francesca. Since the 19th Century, the halls and courtyards, entrances and corridors have been dedicated to celebrated men of culture: artists, benefactors and scientists. The Pinacoteca remains an internationally renowned museum today, adding to the rich cultural history that Milan offers.
