The castle Monforte rises with a quadrangular plant on the calcareous rock of the mountain, it rises to escarpment with of the circular towers places to the edges and with a great rectangular tower, a mastio. The windows are few and square, at equal distances. The walls end with Guelph merlons. The castle was built in 1100 by Ugo II of Molise, above a Samnite settlement. The whole fortification underwent important changes after the earthquake of 1348 and took its present shape in the middle of 1400 by Nicola di Monforte, who later completed the fortification of the castle and of the town of Campobasso. The geographic position of the feud of Campobasso was the best in absolute that allowed the control of the junction between Abruzzo and Puglia and that between the kingdom of Naples and the Adriatic Sea.

The Finibus Terrae Sanctuary Complex, which includes the area of the sanctuary and the lighthouse, is one of the most evocative places on the southernmost tip of Apulia.
