The sober but imposing Norman Tower dominates the entire village of Pietramontecorvino, in the heart of the Monti Dauni.

The castle of Fornelli is difficult to identify for those who expect to find the typical medieval manor. In this case the castle is a medieval village composed of individual "building cells", or houses and churches, enclosed by the walls. In case of an enemy attack, the moat that surrounded the walls allowed to protect the whole village. In the walls are still visible the seven towers built in the Norman period. The towers are in some cases attached to private homes, two are connected to the marquis palace, while in the central tower opens the main gateway to the village.
