Milan is financially the most important city in Italy, and home to the Borsa Italiana stock exchange. It is the second most populous city proper in the country but sits at the center of Italy's largest urban and metropolitan area. While not considered as beautiful as some Italian cities, having been greatly destroyed by Second World War bomb raids, the city has rebuilt itself into a thriving cosmopolitan business capital. In essence, for a tourist, what makes Milan interesting compared to other places is that the city is truly more about the lifestyle of enjoying worldly pleasures: a paradise for shopping, football, opera, and nightlife. Milan remains the marketplace for Italian fashion aficionados, supermodels, and international paparazzi descend upon the city twice a year for its spring and autumn fairs. Milan is famous for its wealth of historical and modern sights - the Duomo, one of the biggest and grandest Gothic cathedrals in the world, La Scala, one of the best established opera houses in the world, the Galleria Vittorio Emanuele, an ancient and glamorous arcaded shopping gallery, the Brera art gallery, with some of the finest artistic works in Europe, the Pirelli tower, a majestic example of 1960s modernist Italian architecture, the San Siro, a huge and famed stadium, or the Castello Sforzesco, a grand medieval castle. So, you have your fair share of old and new monuments. Plus, it contains one of the world's most famous paintings - Leonardo da Vinci's The Last Supper.
