Often labeled as the "forgotten camp," Stutthof was the first concentration camp built outside of Germany by the Nazis. Constructed in September 1939, it was also the last camp to be liberated by the Allies in May 1945. Out of the 110,000 Jews and others held here, an estimated 70% were killed by lethal injections, firing squads, hanging, or gas chamber. The barracks and crematoria, the "hospital," the "holocaust stake" (a memorial on the site of an excavated mass grave), and the exhibits in the museum give you an unnervingly vivid and harrowing picture of the atrocious and inhumane conditions the inmates here endured. Note: Children 13 and under are not admitted. On-site, there is a shortage of English information. The guided tours in English cost 140 z per group (up to 40 people) and must be confirmed in advance via e-mail (firstname.lastname@example.org). The tour takes 1 1/2 to 2 hours.
