There is a church in Milan known by everybody, both locals and tourists. Nope, it is not the Duomo, but a basilica in Corso Magenta. It is Santa Maria delle Grazie, and its fame is mainly due to Leonardo’s masterpiece treasured within its walls: the Last Supper.

Well: it is time for you to know it!
