History

It appears with the toponyms Audelassum, Audelascum or Audelasci since the Longobard era among the possessions of the Abbey of San Colombano di Bobbio, included in the territory of the monastic court of Casasco. In the Middle Ages Avolasca belonged first to the committee and then to the episcopate of Tortona. Only later it was enfeoffed to several Genoese families and followed the events of the Grue valley.
