Behind the small agglomeration of Boiano, on the Matese mountains, there are the ruins of the most ancient castle of Molise. Nearby were found traits of cyclopean walls that suggest a first fortification sannita reused in later periods. During the reign of Frederick II, the area is the scene of struggles between the representatives of the emperor and Judith, wife of Count Tommaso di Celano. In the Registrum Friderici II is made mention of the Civita: in a document of 19 October 1239 the emperor ordered to demolish the houses built near the fortress and to provide promptly to the maintenance of military structures.

The semi-rupestrian church of St. Vitus, almost suspended along the eastern edge of the ravine, is a symbol of the relationship between man and nature in the Gravina of Laterza.
