Bianzano is a comune in the province of Bergamo, in the Lombardy region of Italy. It sits at about 600 metres (2,000 ft) above sea level on a small plateau between the Cavallina and Seriana valleys.
The village has retained the original structure of its historic centre, which includes remains of minor fortified buildings. The imposing medieval Suardi Castle overlooks the valley.
Two other notable monuments are the shrine of Our Lady of the Assumption, dating to 1234, and the parish church dedicated to Saint Roch, dating to 1575.
