The first record mentioning a castrum of Incisa dates from 1022, and very probably refers to the castle standing on a hill overlooking the town of today. In 1223 the Florentines built a new castle on the area of today’s Incisa, which was then enlarged and rebuilt during the 14th century.
Starting from the highest level, the first structure we see is the part behind the fourteenth-century castle walls, over which, in the 18th century, the bell gable of the church of St. Biagio was rebuilt. The open chambers that contained the bells, which have been bricked up, can still be recognized.
In observing the wall surface, the difference between the section that constituted the city walls – marked by regular, parallel courses of sandstone and peddles – and the irregular reconstruction above it, using an abundance of mixed materials, can easily be seen.
Going on, we find on the right the Palazzo Pretorio (Municipal Palace), a structure formed of two bodies which shows clear traces of the Middle Ages and Renaissance periods.
In observing the building with your back to the church, you will note two different stages of construction: the older one on the right is tower-shaped; its upper part it was adapted to the structures built during the second stage, also medieval, but dating from a little later.
After Palazzo Pretorio, we continue along the same street to arrive at a small square overlooked by an important architectural complex from medieval times. Tradition links it linked to the family of the poet Petrarch, whose father, Ser Petraccolo, is thought to have lived in this castle. This group of structures, visibly subjected to numerous restoration and enlargement initiatives, is probably the oldest part of the castle, dateable between the first half of the 13th century and the mid-14th century.
