"Rome, Venice, and Florence are the top three destinations for tourism in Italy. Other major tourist locations include Turin, Milan, Naples, Padua, Bologna, Perugia, Genoa, Sicily, Sardinia, Salento and Cinque Terre. Two factors in each of these locations are history and geography. The Roman Empire, middle ages, and renaissance have left many cultural artifacts for the Italian tourist industry to use. Many northern cities are also able to use the Alps as an attraction for winter sports, while coastal southern cities have the Mediterranean Sea to draw tourists looking for sun. Italy is home to forty three UNESCO World Heritage Sites, more than any other country, including many entire cities such as Verona, Siena, Vicenza, Ferrara, San Gimignano, and Urbino. Ravenna hosts an unprecedented eight different internationally recognized sites. Italy is a true open-air museum with 65 percent of the world's artworks and historical monuments."
