Piazza dell'Anfiteatro Panorama - All Roman towns had baths, forums and amphitheaters. Over time the hot dog and beer venders set up more permanant shops; then lofts above the shops. Over time, as the stones and marble of the amphitheaters were cannibalized to build new buildings, most amphitheaters were converted into piazzas. When you see a row of houses with a rounded walls, you'll almost always find an Anfiteatro piazza inside.
