According to :
It was Charlemagne who donated these lands to the Church of Reggio Emilia, which in turn, through the Bishop Maltraversi Nicholas, sold it in 1050 to Boniface of Canossa.
In 1115 the Countess Matilda of Canossa, daughter of Boniface, enfeoffed the family the territory to the reggianese family Roberti.
From 1115 to 1430, this feud took the name of “Martino de’ Roberti”.
The castle was destroyed in 1157 by Emperor Barbarossa and the Roberti rebuilt it surrounding it with a moat always full of water, drawbridge and enclosing it with wall and two mighty towers.
In 1346 the Roberti allied with the Este family.
In 1353 the Gonzaga besieged and destroyed the castle, which was again rebuilt.
