Canossa is a comune and castle town in the Province of Reggio Emilia, Emilia-Romagna, northern Italy. It is the site where Holy Roman Emperor Henry IV did penance in 1077, standing three days bare-headed in the snow, in order to reverse his excommunication by Pope Gregory VII. The Walk to Canossa is sometimes used as a symbol of the changing relationship between the medieval Church and State.
As of December 2014m Canossa has a population of 3,854, and borders the comuni of Casina, Castelnovo ne' Monti, Neviano degli Arduini (PR), San Polo d'Enza, Traversetolo (PR), Vetto, and Vezzano sul Crostolo. The town was formerly known as Ciano d'Enza, while Canossa was the name of only the castle, now in ruins, once belonging to Matilda of Tuscany, and nearby hamlet, which lie some 8 km east of the town. The new named was decided in 1992.(Wikipedia)
