Gdańsk Polish Post Office Museum
The Polish Post Office in Gdańsk was a symbol of Polish sovereignty within the Free City of Danzig (1920-1939). Its heroic defense against the SS on September 1, 1939, and the subsequent execution of its defenders make it a frontier site where the interwar border conflict became lethal. The museum now housed in the building documents the postal workers' resistance and the broader struggle for Polish cultural presence in the Free City—a struggle that directly affected Kashubian communities straddling the border.
