Only a few of the buildings here are actually curved but they way they're configured makes them look as though they all are. No more beautiful town in the world if you ask me--always go when I'm there.
I spent three days in Florence eating nothing but steak Florentine and gelato. That alone would be enough to put it on the list. Toss in the Uffizi Gallery, Michelangelo’s David, the Doma and the numerous palazzo’s, and it is my favorite city in Italy.
