In fact, the Cathedral dates back to the second half of the year 1000, and was built on the ancient remains of Messapian, Roman and early Christian villages. It has also suffered numerous assaults and has been destroyed and rebuilt several times. One episode above all is certainly the Turkish invasion of 1480, during which one of the saddest pages for the city was written: inside the cathedral, in fact, the faithful and members of the clergy who took refuge within these walls to escape the attack were massacred. The Christian site was defrauded and turned into a mosque, and the artistic treasures it contained were destroyed, until the church and the whole city were liberated by the Aragonese.
