The Oder–Neisse line (German: Oder-Neiße-Grenze, Polish: granica na Odrze i Nysie Łużyckiej) is the basis of the international border between Germany and Poland. It runs mainly along the Oder and Lusatian Neisse rivers and meets the Baltic Sea in the north, just west of the ports of Szczecin and Świnoujście (Former German names: Stettin, Swinemünde).[1]
