It is a municipality in the province of Perugia, located on a promontory, along the Northern shores of Lake Trasimeno: from this vantage point it is possible to admire a superb panorama over the Umbrian countryside and the lake. It is divided between an old main centre, with typical medieval characteristics and surrounded by ancient fortified walls, and a newer area equipped with touristic, sport and bathing facilities. It is an excellent departure point to reach the interesting towns in the nearby, Isola Maggiore and the small village of Castel Rigone, famous for the presence of the Church of Miracles, a splendid example of the Renaissance. The local economy still preserves the tradition of fishing and the processing of iron and copper manufactures.
The area has been inhabited since the Roman times: not far from Passignano, in 217 B.C., took place the historic battle between the Romans and the army of Hannibal that saw victory of the latter. During the Middle Ages, once the fortress was completed, the urban core started to emerge. Passignano submitted the domain of different local Lords: after Uguccione II, it was the turn of the city of Perugia, that for a long while, contended this rule between the cities of Florence and Arezzo, until 1520, when it was acquired by the Baglioni. Later the town belonged to the Oddi, until it passed to the Della Corgna. The latter ceded the fief to the Grand Duchy of Tuscany in 1643.
