Dating back to 1600, l’Arco Borbonico was the entrance of the property of the feudal princes Acquaviva and this testifies to his pre-existence with respect to the construction of the silk factories built in the eighteenth century. The arch is 13 meters high and wide 9, characterized by a single arch, punctuated by rectangular rusticated travertine and emphasized by two pilasters. The lintel is surmounted by the crest of the Bourbon, which towers flanked by two lions of the sculptor Brunelli.
