The pentagonal tower

Everything is well in the 13th century when the town left Petra Castellana and had just settled in the plain, the country is peaceful and prosperous. This is not the case in the second half of the 14th century when economic crises and social unrest were more and more numerous. Times are no longer safe and the town is fortified in 1359. The wall, lined with 14 square towers, must adapt the shape of the town exactly in the same manner it was at that time. Hence the construction to the upper corner of this high tower that dominates the plain.
