Polish Corridor
Preserved but no longer current.
The territory given to Poland by the Treaty of Versailles to enable her to have access to the Baltic Sea. It followed roughly the line of the Vistula and reached the sea to the west of Danzig (declared a free city) and the port of Gdynia was built by Poland for her commerce. The Corridor cut off East Prussia from the rest of Germany and was one of the causes of irritation which eventually led to World War II.
Era: ca. 1898 (Victorian)
