That marks quite an increase from the seven thousand Nazi camps and ghettos that researchers expected to find when they began their work thirteen years ago. The figure doesn’t just include death camps like Auschwitz (photo) but also, among others, some thirty thousand forced labor camps and five hundred brothels filled with sex slaves.
“The numbers are so much higher than what we originally thought,” said Hartmut Berghoff, director of the German Historical Institute in Washington, D.C. Researchers now estimate that as many as twenty million people died or were imprisoned in the sites they have identified, in an encyclopedia that is expected to have seven volumes by 2025.
