To commemorate the terrible martyrdom of the saint, for which the town is named, a fire festival, called Focarazza, is held in Santa Caterina di Roccalbegna. An oak trunk, called Stollo, with garlands of ivy is raised. On the following day, this ‘stollo’ is the object of contestation among the districts of this town in the province of Grosseto. The team that catches the ‘stollo’ burns it and spreads its ashes to ensure good harvest.
