 It is probable, however, that the settlement has arisen during the Middle Ages, perhaps starting with a small defensive element, a sighting tower guarded by some important aisles important for that time.Stroncone was, in fact, in a border area between the Longobard Duchy of Spoleto and the territory under the control of the Byzantines.Right from the name of one of the Dukes of Spoleto, Ugo, it would derive that of the center, obtained from the original "castrum Hugonis", corrupted in "Castrugone", "Strungone" and finally "Stroncone".
