 Although the legend has never been confirmed by documents, it is the basis of the city coat of arms which shows a wolf escaping from the main tower of a castle.It reminds the daring escape of a noble named Lupo da Limonta ("Lupo" means wolf), who was imprisoned in the tower presently located in via Roma 7, which still shows a Visconti coat of arms engraved on its walls.During the fight for power between Visconti and Sforza families, the noble prisoner was helped free by a jester named Tremacoldo, thanks to a ruse.
