The second set of walls dates back to the 13th – 14th century and was restored in the 20th century by the engineer Gino Zani. These defensive walls have guaranteed the defense of the city over the centuries through the use of crossbows. Along these walls, there are two gates giving access to the Old Town: the New Walls Gate (Porta della Murata Nuova) and the Fratta Gate (Porta della Fratta).
