It is raining when we reach Pacentro. Gianfranco is waiting in the main square, dominated by the fine church of Santa Maria Maggiore, and a splendid stone fountain in the middle. The church goes back to the late 16th century, and shows a belltower with a peculiar pyramidal cuspid and, right of the portal, a ceramic sunclock. Under umbrellas, through the steep medieval lanes, the escorted tour begins. We pass the Chiesa di San Marcello, the most ancient religious building of Pacentro, originally called Chiesa della Trinità: founded in 1047 by Adalbert a monk from San Clemente a Casauria, was destroyed by a fire and then rebuilt and reopened by Berardo bishop of Forcona in 1166.
In the 15th century the castle became the residence of the Caldora-Cantelmo family. Jacopo Caldora was born in Castel del Giudice on 1368 and married Rita Cantelmo. Jacopo did not take any nobility title and was happy with his name - When the king offered him more honors, after his key role in the defeat of Braccio da Montone, he said his own Caldora name was his greatest honor already. He was also the Lord of Bari, Vasto, Monteodorisio, Arce, Trivento, Palena, Anversa, Valva, Campo di Giove. After the defeat of Braccio da Montone, his power was so great that the King himself started to fear. Then his son Antonio Caldora sided with the Anjou against his sovereign, Ferdinand of Aragon. The rebellion was defeated in a historical battle near Montorio on 7 may 1486, and the Caldora lost all their possessions. Meanwhile fire weapons had been introduced, and in the 15th and 16th centuries rounded walls were added to better defend the inside quarters from artillery fire. After the fall of the Caldora, the castle and fiefdom saw a number of different lords. From the castle walls and enclosures, a great view of the little town below and the mountains and hills in front.
