 It is probable that Stroncone, along with other Guelphic parts centers such as Narni and Miranda, suffered significant damage during the passage of imperial troops, the Lanzichenecchi, in 1527.The signs of subsequent reconstruction are still evident in many buildings, especially in the isolation of the municipal building and in the walls.The political and economic influence of the minor brothers in the life of the city from the fifteenth century should not be forgotten, so as to favor Stroncone as in the main centers of Umbria, the birth of a mountain of Pietà (1466) and of a Monte Frumentario (1489) with the aim of combating illicit and immoral economic activities.
