The Suardi were a Ghibelline-allied noble family in medieval Bergamo. Their Guelph opponents were the Colleoni.[1]
In the 14th-century, the family was allied with the Visconti of Milan; Giovanni Suardi even married one of the daughters of Lord Bernabò. Guiscardo Suardi was a 13th-century bishop.
Suardi Castle still stands in Bianzano on a hilltop above the Cavallina and Seriana valleys. Suardi Tower is located in Trescore Balneario. The Suardi Chapel at Trescore Balneario is decorated with 16th-century frescoes by Lorenzo Lotto.
