Mura Medievali e Porta di San Gillio

Some remains of the southern and western part of the 12th century city walls still stand on via Nino Bixio. There are three postern gates dating from the earliest period of this segment of walls in the southern part, while other more roughly executed openings are of later date. The Wall at the southwest corner is built in rough-hewn stone and adjoins a large round archway in dressed stones, called in old texts Porta S. Pietro.Several stages in construction dating from the 13th and 14th centuries can be discerned along the remaining stretch of the southern walls, built in stone with parts in brick, like the battlements.
