 The name "Molinella" comes from the Italian word for mill, "molino"; That is because during the Middle Ages there was a large number of watermills in this area.The village was created before the 14th century on a hillock between the "marshes of Marmorta and Marrara" and just south of the Po di Primaro river.The village was a "Customs place" on the border between "Bologna Territory" and "Ferrara Territory" until the 18th century.
