 The place was known as Mansio ad Arnum, as evidenced in the Tabula Peutingeriana, and it is probable that in the area there was a bridge that, during ancient Rome, permitted the crossing of the river Arno.During the 5th and 6th centuries AD, the area faced threats of barbarian invasions, and the population left the plains and relocated to the surrounding hills.This phenomenon reached its peak during the 10th century, during the time of power struggles between the great families Guidi, Cadolingi and Alberti.
