The "Piazza della Principessa Margherita" is down the hill from the fortress and Duomo on the via Matteotti. The principal building on the piazza is the former "Palazzo dei Priori" or "Palazzo Comunale" (built late 13th, early 14th century), now town hall. The palace is adorned with the coats of arms of the Podesta, once rulers of the city. A tall medieval tower is incorporated into the palazzo. Close by is a Renaissance-style building with six round arches, called "La Loggia", for which construction began at the very end of the 14th century and finished in the early 15th, but which has undergone much restoration work over the subsequent centuries.
