Jadovno concentration camp
The Jadovno concentration camp was a concentration and extermination camp in the Independent State of Croatia (NDH) during World War II. Commanded by a member of the Ustaše Militia Juraj Rukavina, it was the first of twenty-six concentration camps in the NDH during the war. Established in a secluded area about 20 kilometres (12 mi) from the town of Gospić, it held thousands of Serbs and Jews over a period of 122 days from May to August 1941.
