This picturesque Umbrian city has a history that spans many eras. The city wall and arch are Etruscan; the sixth-century Sant'Angelo church was built atop a Roman temple; the town's cathedral is both Gothic and Renaissance. If you have a sweet tooth, visit the famous Perugina chocolate factory; if you have a full set of sweet teeth, visit during the Eurochocolate festival, held in October, when the entire town reportedly smells of chocolate.
