As a result of researches, studies and excavations in the santeliano countryside, the dynamics of medieval settlements have been reconstructed and traced. To date, the investigations, mostly concentrated on the high ground of Pianisi, have brought to light several testimonies and remains of the inhabited area with large sections of the walls of the upper terracing of the fortified village, the great tower that dominates the inhabited area and the church of Santa Maria ad Nives with its bell tower.

The Swabian-Angevin Fortress of Lucera dominates the Tavoliere delle Puglie plain from its privileged position. The fortress is the result of the achievements and military ingenuity of Frederick II and Charles I of Anjou.
