The festival commemorates, with flag-waving and archery tournaments in medieval costumes, a meeting of Federico Barbarossa with papal envoys that took place in 1155. When the most powerful and feared man of the time, Federico Barbarossa, reached Siena to meet with the papal envoys and emerged from the rendezvous as emperor.
Since 1962, every third Sunday in June this historical event is commemorated in San Quirico. Two days of folklore, tradition, entertainment and fine cuisine.
