Castello Suardi, Medieval castle in Bianzano, Italy.

Castello Suardi is a fortification with a square layout, double walls, and two defensive towers built in stone with carefully cut ashlar work at its base. The structure retains its medieval architectural form and defensive features in their original arrangement.

A stone on the courtyard portal bears the date 1233, but historians question it: wall remains and a tower base found nearby suggest the castle came after the village. The first document mentioning it dates from the 14th century, when it belonged to the Suardi family. In 1367 Giovanni Suardi married Bernarda Visconti, daughter of Bernabò, regent of the Duchy of Milan, and received the castle as a gift. To avoid demolition ordered by the Republic of Venice, the Suardi removed the battlements and covered the structure with a roof, turning it into a residence.

The entrance hall displays frescoes from the Lombard school showing playful putti and four cardinal virtues. These decorations reflect the artistic taste of the Suardi family who lived and ruled from this place.

Visits are possible through guided tours arranged by the Bianzano Town Council or the Pro Bianzano Cultural and Tourist Association. It is recommended to contact one of these organizations in advance to arrange a tour.

The historical reenactment of Giovanni Suardi's 1367 marriage to Bernarda Visconti, daughter of Bernabò Visconti, regent of the Duchy of Milan, is held annually on the first weekend of August and involves the whole village of Bianzano. Giovanni received the castle itself as a gift on the occasion of the wedding.
