GoKawiilPoland built its own Baltic port at Gdynia in the 1920s after Versailles left it without reliable sea access
After the First World War, the Treaty of Versailles granted the newly reconstituted Poland a narrow corridor to the Baltic Sea but no major port of its own, since it was hemmed in by Germany, East Prussia and the German-majority Free City of Danzig. In 1920 Polish authorities decided to construct a new port from scratch, choosing the small fishing and holiday village of Gdynia as the site for what would become the country's gateway to the sea.
