Stettin Lagoon

The Stettin Lagoon spreads across the mouth of the Oder behind the islands of Usedom and Wolin. River water reaches the Baltic through three outlets: the Peenestrom to the west, the Świna between the islands and the Dziwna to the east. The lagoon offered a sheltered waterway between the Oder and the sea, though its shallow waters and separate passages required navigators to find their way through a complex coast.
