The festival traces its origins back to a 14th-century dispute between Chieti and Bucchianico over the borders. As the Chieti army approached the walls of Bucchianico, the townspeople faced a perilous situation. However, in a dream, Sant’Urbano appeared to the hereditary Sergentiere, leader of the militia from the Tatasciore family, and suggested a clever strategy. The men, adorned with red and blue bands and colorful feathers, ran along the battlements, creating an illusion of a larger defense force. Meanwhile, led by the Banderese, the countryside population sought refuge within Bucchianico’s walls. The ruse succeeded, dissuading Chieti from attacking.

Today, the festival commemorates this historic event. Women don elegant traditional dresses and carry enormous baskets filled with handmade crepe paper flowers, reciting the rosary. Young girls, known as “pacchianelle,” proudly balance these baskets on their heads. The men construct carts, some representing aspects of peasant life, while the Banderese family creates carts symbolising items brought by displaced peasants seeking shelter within Bucchianico’s walls: bread, bed, wood, and wine. Traditionally on the Sunday before  May 23, the procession, led by the Banderese family, commences, carrying the ribboned calf, the patron saint’s image, and donations. After reaching the Monument to the Fallen, the sergeant welcomes the Banderesi, entering through the church of Sant’Urbano Papa. The celebration continues with various traditions, including breakfast with veal stew, paying homage to the Chieti soldiers’ meal before the siege. The festival culminates on May 26 with a grand parade through Bucchianico’s main churches, offering Ceri at the reliquary of Sant’Urbano.
