The Celebration of 1111 refers to the famous historical event in which the emperor Henry V, after having given Matilda di Canossa as Imperial Vicar, enters the Castle of Bianello and, in front of Donizone, Arduino della Palude, the Bishops of Reggio and Parma, the German Knights and the Benedictine friars, toast the event just completed, which sanctions the rediscovered peace between the two.
