a historical reconstruction by Franca Manenti Valli of the Castle of Canossa in the time of Countess Matilda of Tuscany.
After some occasional neolitic settlements, the hills between the valleys of the river Enza and Secchia, were colonized by romans who developed there famous centres like Luceria, not far from what is today called Ciano. On the same cliff of Canossa, some findings suggest the hypothesis of an ancient roman blockhouse for this important residential centre. After the dark period of the Late Middle Ages, when the Lombard and Byzantine invaded the land devasting it, Atto Adalberto, a Lord from a Lucca family, decided to build here a fortified system that had its most significant dimensions between the XI and the XII centuries. Meanwhile a net of villages was developing all around saving pastures and cultivations from the savage woods. But it is just under Matilde, the Great Countess, that these lands got a continental reputation, playing an important role in the quarrel between the Pope and the Emperor. Matilde's feud was extremely powerful, covering from Mantova to Lucca, to Florence, to the Po's mouth. She was an european woman, from an important family operating internationally, from Italy to Lorraine. She gave a fundamental impulse to the origin of the University of Bologna; she was also one of the main responsible of the reformation of the church engaged by Gregorio VII. After the matildic renaissance, the local history witnesses first the predomination of the commons, then the power of local noble families. Between the 1425 and the 1427 the largest part of the matildic territories suffered the invasion of the Estensi family, who hold them for centuries.
