Polish Corridor
The Polish Corridor (German: Polnischer Korridor; Polish: korytarz polski), also known as the Pomeranian Corridor, was a territory located in the region of Pomerelia (Pomeranian Voivodeship, Eastern Pomerania), which provided the Second Polish Republic with access to the Baltic Sea, thus dividing the bulk of Weimar Germany from the province of East Prussia. At its narrowest point, the Polish territory was just 30 km (19 mi) wide.
