Researchers have found that there were around 20,000 Nazi prisons, ghettos and camps in WWII, over 4 times the number they were expecting to catalogue.
The Encyclopaedia of Camps and Ghettos 1933-1945 aims to catalogue most of Adolf Hitler’s Nazi concentration camps, POW camps, prisons, and other persecution sites used during the Second World War. Project director Geoffrey Megargee of the US Holocaust Museum in Washington DC told Deutsche Welle that the first surprise he encountered in this endeavor was realising how far the network stretched.
“When the project started we thought we were dealing with perhaps 5,000, perhaps 7,000 sites. But as we started to get into the research for the encyclopaedia we started to see the numbers go up and up and up, and within a couple of years we were up around 20,000,” he said.
