Milan is a historic city comprising a web of streets built around the Piazza del Duomo, the city's main hub. There are many historic locations to visit in Milan, including the Duomo, the world's largest Gothic cathedral, which was begun in 1386 and took almost five centuries to complete. An incredible building, with a strange mixture of Baroque and Gothic decoration.Inside can be found a large crucifix said to contain a nail from Christ's cross. Milan is a testament to the prestige-building of the Visconti dynasty and their successors, the Sforzas, who ruled here in Renaissance times; and the contemporary aspects of the place represent the leading edge of Italy's fashion and design industry, not to mention a nightlife scene which is perhaps Italy's most varied.
