Milan is the commercial and financial center of Italy. Historically, it prospered because of its command of trade routes across the Alps and the plains of the Po River Valley. The city can boast one of Europe’s most spectacular Gothic cathedrals, plus a wealth of masterpieces, including “The Last Supper” by Leonardo da Vinci. La Scala hosted the premieres of Verdi’s “Nabucco” and Puccini’s “Madame Butterfly” and “Turandot.” Most of the famous Italian fashion brands are headquartered in the city.
