Stutthof was a Nazi German concentration camp established in a secluded, wet, and wooded area near the small town of Sztutowo(German: Stutthof) 34 km (21 mi) east of the city of Danzig in the former territory of the Free City of Danzig. The camp was set up around existing structures after the invasion of Poland in World War II, used for the imprisonment of Polish leaders and intelligentsia. The actual barracks were built the following year by hundreds of prisoners.
Stutthof was the first Nazi concentration camp set up outside German borders in World War II, in operation from 2 September 1939. It was also the last camp liberated by the Allies on 9 May 1945. It is estimated that between 63,000 and 65,000 prisoners of Stutthof concentration camp and its subcamps died as a result of murder, epidemics, extreme labour conditions, evacuations, and lack of medical help. Some 28,000 of them were Jews. In total, as many as 110,000 people were deported there in the course of the camp's existence. About 24,600 were transferred from Stutthof to other locations.
