教皇派と皇帝派
In the Middle Ages the Castle of Breno had two towers, one belonging to the Guelph family Ronchi, the other to the Ghibelline family Alberzoni. In the 1397 peace of Breno between Guelphs and Ghibellines, the representatives of the community of Breno sided both with the Ghibellines and the Guelphs.
