Stutthof was a
Nazi German concentration camp built in a secluded, wet, and wooded area near the small town of
Sztutowo 34 km (21 mi) east of the city of
Gdansk in the former territory of the
Free City of Danzig. The camp was set up around already existing structures after the
invasion of Poland in World War II, used for the imprisonment of Polish
intelligentsia. The actual barracks were built in the following year by hundreds of prisoners enslaved in specialized commandos. Stutthof was the first camp outside German borders, in operation from September 2, 1939, and the last camp liberated by the
Allies on May 9, 1945. More than 85,000 victims died in the camp out of as many as 110,000 inmates deported there.
