The bell tower of Cassano d’Adda was commissioned by Beatrice Regina della Scala in 1381, in a period which was marked by the passage from the Lombard Romanesque style to the Gothic one. The bell tower is 42 meters high and represents a national monument. It originally served also as a lookout post on Gera d’Adda: that is the reason why it was open at the top. In 1861, the parish Don Milani equipped the tower with the current complex of eight bells.
