[custom_adv] This is a list of Italian dishes and foods. Italian cuisine has developed through centuries of social and political changes, with roots as far back as the 4th century BC. Italian cuisine has its origins in Etruscan, ancient Greek, and ancient Roman cuisines. [custom_adv] Significant changes occurred with the discovery of the New World and the introduction of potatoes, tomatoes, bell peppers and maize, now central to the cuisine but not introduced in quantity until the 18th century. [custom_adv] The cuisine of Italy is noted for its regional diversity, abundance of difference in taste, and is known to be one of the most popular in the world, with influences abroad. [custom_adv] Pizza and spaghetti, both associated with the Neapolitan traditions of cookery, are especially popular abroad, but the varying geographical conditions of the twenty regions of Italy, together with the strength of local traditions, afford a wide range of dishes. [custom_adv] Both for its history as the capital of much of Europe and for its present day role as one of Europe's most vibrant cities, for most tourists traveling to Italy, Rome heads the list of places to visit. Relics of its ancient glories—the Colosseum, the Forum, the Pantheon, the Appian Way, and the Palatine Hill—vie with the vast riches of the Vatican as the top attractions. [custom_adv] The showcase of the Italian Renaissance, Florence can at times seem like one giant art museum. The Duomo, the Cathedral of Santa Maria del Fiore, is a landmark of world architecture, topped by its gravity-defying massive dome. Together with its marble-inlaid bell tower by Giotto and its octagonal Baptistery with its incomparable bronze doors by Ghiberti, this is one of the world's finest ensembles of Renaissance art. [custom_adv] Half a dozen art museums brim with paintings and sculpture, while more masterpieces decorate its churches. Before you overdose on art in the Uffizi Gallery and Pitti Palace, stroll through the Boboli Gardens and explore the artisans' studios and workshops of the Oltrarno, or shop for leather in Santa Croce. [custom_adv] Who could fail to love a city whose streets are made of water, whose buses are boats, and where the songs of gondoliers linger in the air? It is a magic city, and its major attraction to tourists is the city itself. The hub of the city is the broad Piazza San Marco, St. Mark's Square, surrounded by several of its top tourist attractions. The great Basilica of St. Mark stands beside the Doge's Palace, and overlooking both is the tall Campanile. [custom_adv] Gondolas congregate at the end of the plaza in the Grand Canal, and in the other direction, a gate under the clock tower leads into a warren of narrow, winding passageways, where you're sure to get lost on the way to Rialto Bridge. But getting lost is one of the greatest pleasures of Venice, where a postcard scene awaits around each corner. [custom_adv] The undulating landscape of Tuscany is crowned by stone towns whose foundations go back to the Etruscans. Each sits atop a hill, and many still have the castles and towers that once defended their commanding positions.
