The castle in the current form was probably erected between 1450 and 1475, at the initiative of the Visconti di Brignano transforming the previous 14th-century quadrangular fortification with a surrounding moat.

[3] In 1442 Filippo Maria Visconti donated the castle to the noble De-Isacchi family from Treviso.

Shortly after, it passed to the Visconti di Brignano, who gave it the present form.

The castle then had several owners: the Visconti-Aimi di Brignano, who resided in the nearby Palazzo Visconti di Brignano Gera d’Adda, the Marquises Bigli, and finally, the Marquises Crivelli.

[2] The Pagazzano territory was disputed over the centuries by surrounding ruling forces, and various Visconti descendants.
