In the center of the village of Bianzano stands an ancient castle whose history is still partly shrouded in mystery: a square-plan building whose corners are aligned with the four cardinal points. Two defensive walls, of which remains are found today, surround the structure in the center of which stands an imposing keep. What saved this castle from destruction during the period of the Republic of Venice was the intuition of the Suardi family, who decided to remove the battlements from the walls to make it resemble a dwelling as much as possible and not a fortress. Their coat of arms is still found today on the entrance portal to the castle.

The current Terzi Castle has very ancient origins, dating back to the Early Middle Ages. It was originally a fortified Benedictine monastery, destroyed by Charlemagne's Frankish army in the 8th century. Rebuilt as a castle in the 9th/10th century, it belonged to the Mozzo family and then to the Suardo family, who extended their dominion over the entire valley, also owners of the Bianzano Castle. In the 15th century, following the imposition by the Venetian Republic of the demolition of every stronghold present in the territory of the Serenissima, the Suardo family, in order to avoid its destruction, made it a stately home. Finally, the property passed to the Terzi family, who sold it in 1930, by then completely abandoned and in ruins, to the British countess Winifred Terni de Gregory. From 1937 to 1945, she renovated the property as it appears today, including the gardens. Currently the entire complex is temporarily rented for important events or weddings.

13th century castle of the Suardo Counts. Every year, in August, there is a historical reenactment: "In 1367, Giovanni di Baldino Suardo and Bernarda Visconti, daughter of Bernabò, Lord of Milan, recently married, arrived in the village of Bianzano where the Castle that their father Baldino had given them stood. The people of Bianzano welcomed the couple with great celebrations, frescoing the atrium and entrance portal of the Castle in their honor. The Bianzano branch of the Suardo family was born, and is still alive today. The reenactment, therefore, stages the arrival of Giovanni Suardo and Bianca Visconti at the Castle and the celebrations that ensued."
