With Faeto and Celle di San Vito, Castelluccio completes the settlement system developed along the Celone valley. The agglomeration, in fact, gathered around the massive circular tower, strategically dominates the entire valley from which it takes its name.
The origins of the town date back to the early eleventh century, at the time of the Byzantine domination of Daunia. The site, built in an area of archaeological finds, provided a strategic observation point on the Traiana road and a very important garrison guarding the nascent Troia. The urban structure, originally equipped with walls and two large gates, Pozzo and Piscero, was centered on the circular tower that still dominates the town. The mighty construction was part of a larger plan of territorial reorganization operated along the subapennine cordon by the catapano Basilio Boiannes, representative of the authority of the Eastern Empire in Puglia, in the defensive function of the border with the Longobard Duchy of Benevento.
The defensive character of the tower is evidenced by the compact shape engraved by small openings and by the elevated position of the entrance reachable with a removable wooden ladder in case of attack. Near the tower stands the parish church dedicated to St. John the Baptist, built in the middle of the last century, which preserves interesting evidence of the Baroque era. The church of Santa Maria delle Grazie, dating back to the 16th-17th centuries, is rich in precious furnishings.
