The Sanctuary of Maria Santissima Addolorata in Castelpetroso is located at the foot of Mount Patalecchia. Its neo-Gothic structure, its domes, spires and white stones make it stand out in the green of the surrounding forest. It was built following a miraculous event: on 22 March 1888, two peasant women, Bibiana and Serafina, were in the area known as "Cesa tra Santi", grazing two sheep. One of them was lost and the two women did their best to look for it.

The Acquaviva d'Aragona Castle, the medieval symbol of the town of Conversano, dominates the area from the highest point of the historic centre.
