The Pignatelli castle, with its beautiful crenellated towers, dominates the Volturno plain on the Isernia-Venafro road. In the past it was a key point of entry into the "Contado del Molise" as a lookout on the Via Latina. A first settlement nucleus, in the places where today the castle rises, dates back to the Samnite age. The origins of the castle-fortress instead date back to the Lombard period, when the population was forced to retreat to face the violent Saracen raids. It was with the Norman domination, however, that the castle, for purely military needs, was enlarged compared to the original Lombard structure and strengthened with the erection of walls, which also included some homes. In 1193 the entire country paid dearly for its deployment against the Emperor Henry VI in favor of the Norman Tancredi.

The Port of Tricase is a now a dynamic extended museum, a place where knowledge relating to the traditions of the sea and the coast can be developed, collected, exchanged and further explored.
