Buronzo, located in an ideal position for strategic control over the surrounding area, began to build its Castle in the thirteenth century. A particular type of Castle, rare in the Vercelli area, was built: a group of medieval fortified houses whose defense was guaranteed by the garrisons present in each of them. The structure was renovated several times.

Over the centuries, the Buronzo families faced many crises and wars, but already in the seventeenth century the Castle had lost its military role.
