Piazza della Fiera
The square, which covers a spacious parking garage, is flanked by a long stretch of embattled wall, built around the town in 1230. On the eastern side of the square, at the top of Via Mazzini, you can find the remains of "Il Torrione", also called "La Rotonda": this is a circular tower built in the sixteenth century and subsequently modified many times. Now it contains apartments.
