The town has a rich calendar of events. Holy Week processions take place at night and wind through the streets of the town, enlivened by the participation of the three religious companies dedicated to charity work since the Middle Ages who, dressed in traditional hoods, recite prayers carrying crosses and statues.
The entire month of May is dedicated to the exhibition of local gastronomic and handicraft products and agricultural machinery, as well as cultural events such as conferences and exhibitions, during the Castiglionese May.
On the third Sunday in June, the Palio dei Rioni is held: the ancient horse race in the round in which the districts of Porta Fiorentina, Cassero and Porta Romana compete. On Sunday morning outside the Rivaio Church, the horses and jockeys who will compete are blessed; in the afternoon, a costume parade is held with ladies, knights, priors and armed men, accompanied by musicians and flag-wavers. In Piazza del Comune, the reading of the challenge is held, followed by the parade of all the figures and the majestic ox-drawn cart leading the Palio. At 7 p.m., in the round of Piazzale Garibaldi, the long-awaited race begins.
The Castiglioni Film Festival returns every year in the last week of July at the Cassero Archaeological Area. On the program, outdoor screenings of films and meetings-interviews with actors, directors of national and international fame.
During the days of Ferragosto (15 August), the historic center of Castiglion Fiorentino comes alive with events that harken back to the 1950s and 1960s during the Vintage Festival. Handicrafts, vintage clothing and objects, musical entertainment, along with typical menus: a dive into the fun, colors and style of the rock 'n roll and swing years.
The Living Nativity is a tradition involving hundreds of extras, men, women and children of all ages. The re-enactment, which usually takes place on December 26 through the alleys of the historic center, reproduces various scenes from life at the time of Jesus: Herod's court, Roman soldiers, shepherds, taverns, the fishermen's village, and, more generally, typical scenes from the culture of the time, providing the visitor with a fascinating journey through ancient crafts and old traditions.
