The fortified complex represents one of the best-preserved examples of Lower Medieval military architecture in the province of Brescia. The castle was traditionally called Oldofredi because of the presence in Iseo of this noble Ghibelline family, who were friendly to the Visconti and the Scaligeri and fierce opponents of the Republic of Venice.

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.
