The former Ospedale Maggiore, now the University of Milan, is comprised of multiple courtyards, surrounded by stately buildings. We enjoyed a stroll through beautiful and largely empty courtyards (students were on vacation). Enter from Via Festa del Perdono.
This is the first and oldest hospital in Milan. The architecture of the buildings and surrounding walls are very unique with many statues and cravings on the exterior.
If you are interested, do read up about the history regarding the architecture prior to the visit.
