Since 1793, every year, on August 25, 26 and 27th, the celebrations and a solemn procession with ride in honor of Saint Oronzo, the protector of the White City in Ostuni. Have been taking place. In 1657 Ostuni and other small cities in Terra D’Otranto me and Marco were not touched by plague thanks to a miracle which popular belief attributes to Saint’Oronzo.For this reason people from Ostuni are devotees. They walk in procession to the Sanctuary built in honor of Saint Oronzo on the ridges of Monte Morrone.
