The Gallery of Maps is a stupendous hallway where geography and history are perfectly intertwined. Created at the end of the 16th century, the entire room is dedicated to customized maps, which display the whole of Italy. On one side of the 393-foot long gallery are two representations of the country: one from the Imperial Roman Era and the other from the 1500s. Each map shows political happenings, religious roles, and major battles. The ceiling is no less remarkable, with frescoed scenes displaying episodes and miraculous events of apostles, saints, and martyrs, which are linked to the geographical maps below.
