The four hills which punctuate the landscape to the left hosted as many fortresses built between the 10th and 11th centuries. These were natural and fortified outposts defending the Castle of Canossa.
Interesting geological-environmental routes in the territory are the sign of a remarkable naturalistic landscape.
With the exception of Bianello, which was recently restored, the only remains of the other towers are a few ruins. In May/June every year is the celebrated Historical Matilde di Canossa Procession.
