The walk to the center also passes by Palazzo Roberti-Alberotanza, which stands out in the central and verdant Piazza XX Settembre, built in the second half of the eighteenth century, also known as the Palazzo delle Cento Camere, now owned by the municipality. Wedged between buildings from the 70s and blocks of flats, there is also the ancient watchtower in the walls, which today however does not appear in its full splendor, waiting to be restored.
