This is a permanent outdoor exhibition located on the Westerplatte, where World War II broke out. Split into four parts, the first shows the life of the peninsula from its formation and development as a spa resort which lasted up until WWI. The second focuses on the development of the Polish Military Transit Depot in the inter-war years which leads into the third part and the defence of the peninsula in September 1939. The final part shows the significance of Westerplatte in the collective consciousness of Poles and its effect on the policies of the communist government up to 1989. It's well worth viewing and gets the history of the area across very well and very concisely.
