The Adriatic coast city of Ravenna is an absolute delight—a small, clean, northern-style town that is very walkable. There are several Romanesque basilicas decorated with mosaics that would floor even the most jaded tourist, and there are no crowds to see those jewels, especially when compared with the anxiety-inducing throngs of Florence and Venice. The city of mosaics can be visited in one day, during which you can make an art trip into the Roman Empire’s past glory.
