The famous general peace that had held the bridge of Minerva in Breno, pompously and solemnly ratified with great oaths in 1397, was short lived and feuds took up so much that in 1403, the fortress of Niardo, which stood on the "Dos del Castel", became the refuge of the usual Baroncino Nobili from Lozio, which often away from their land in the narrow and well defended Lozio valley, just niardese departed from the castle for his bloody expeditions and for the numerous raids that many deaths and property damage produced between the Ghibellines.
