t the heart of the city is the Fountain of Neptune, which is a masterpiece of marble sculpture at the terminus of a still functioning Roman aqueduct. The Arno river, which cuts through the old part of the city, is as much a character in Florentine history as many of the men who lived there. Historically, the locals have had a love-hate relationship with the Arno — which alternated from nourishing the city with commerce, and destroying it by flood. Many of the bridges across the Arno were built by the Romans. One of the bridges in particular, however, stands out as being unique — The Ponte Vecchio, whose most striking feature is the multitude of shops built upon its edges, held up by stilts. First constructed by the Etruscans in ancient times, this bridge is the only one in the city to have survived World War II intact. The most famous palace in the city is San Lorenzo, which has become a monument to the Medici family who were one of the most powerful families in Florence during the 15th century. Nearby is the Uffizi Gallery, one of the finest art galleries in the world.
