 Therefore signs of ancient settlements were not found here, but not far from municipality’s boundaries in Cogozzo not far from Viadana and near Coenzo were found traces of two Bronze Age villages called "terramare".The southern part of the territory still shows the signs of Roman "centuriation".Casale, the oldest inhabited centre, was founded on a river island; in 890 it was defined as ""insula iuxta Padum"" (island near Po) to become some century later ""Casalis Ripae Padi"" (that means Casale near Po riverside) because the river moved northwards.
