High 40 meters, the sober structure still has well visible elements that were used for the defense of the fortress, such as archers' slits and storm drains used to throw hot liquids on the assailants. Equally easy to find are the additions of the Angevin era: on the south side of the elegant mullioned windows and on the east one a pretty balcony. Inside, a skilful restoration has mixed original elements, such as the spiral staircase in oak wood, with modern materials and structures, such as the new steel and crystal staircase.
In the thirteenth-century stone sentinel, you can visit a permanent multimedia exhibition on traditions, first of all the devotion to Saint Albert the Norman and the penitential pilgrimage that the Petraioli perform in his honor every May 16.
Do not miss the view, which embraces the north of the Tavoliere up to the promontory of the Gargano, given by the beautiful crenellated roof terrace. To the south you can see the silhouette of the Devil’s Chair of Montecorvino (Volturino).
