Located in south central Germany near the border with the Czech Republic, Flossenbürg was a concentration and labor camp with an extensive network of satellite camps. Many of its inmates—labeled political enemies, criminals, or “asocials” by the Nazis—were assigned to work in the nearby granite quarries. Few Jews were imprisoned here until 1944 when thousands arrived from Hungary and Poland on death marches. Protestant theologian and anti-Nazi conspirator Dietrich Bonhoeffer was hanged here on April 9, 1945. More than 90,000 persons were imprisoned in Flossenbürg over the course of its existence, about a third of whom died in the camp.
