The location is indicated by the name of Bellona or Bellonia, and it was an important road junction, whereas it was along the shortest route that linked Cortona to Perugia, and on the road connecting the Upper Tiber Valley to Lake Trasimeno. On 25 June 217 BC, the Carthaginian and Roman troops clashed in the valley of the Niccone River, at Bellona; the Romans, veterans who escaped from the battle of Trasimeno, were defeated. These events are remembered by a large number of local place names: Pugnano, Monte Corvino, Peggio (now Preggio), Pian di Marte.
