Unlike the other three mills on the Lemene river, namely Stalis, Boldara and Portovecchio, located in the countryside or in small hamlets, those of Portograuro are located in the center of the largest town that the river meets. Portogruaro (simply said Porto, in Venetian language, and Puart in Friulano) has almost 25,000 inhabitants. The river enters from the north, flows by the cathedral and the municipality (the mills are here, in the heart of the town) and exits to the south, to reach the town of Concordia Sagittaria and the Adriatic sea.
Two wheels are left, both in motion. For those who watch from the bridge, they are preceded by a large an anchor placed on the ground at the apex of a small island; as the name implies, Portogruaro was a docking point for loading and unloading goods).
