Piast Canal
Poland
The Piast Canal (Kaiserfahrt, Kanał Piastowski) is a ship canal that connects the Szczecin Lagoon in the estuary of the Oder river with the Baltic Sea via the Świna river. The eastern part of the Świna is bypassed by the canal, providing a more convenient south-north connection for large ships from the Baltic to reach the industrial city of Szczecin (Stettin) more easily.
