Over the 12 years of use as a concentration camp, the Dachau administration recorded the intake of 206,206 prisoners and deaths of 31,951. Crematoria were constructed to dispose of the deceased. Visitors may now walk through the buildings and view the ovens used to cremate bodies, which hid the evidence of many deaths. It is claimed that in 1942, more than 3,166 prisoners in weakened condition were transported to Hartheim Castle near Linz, and were executed by poison gas because they were deemed unfit.[15]:137[21]
Bergen-Belsen [ˈbɛʁɡn̩.bɛlsn̩], or Belsen, was a Nazi concentration camp in what is today Lower Saxony in northern Germany, southwest of the town of Bergen near Celle. Originally established as a prisoner of war camp,[1] in 1943, parts of it became a concentration camp. Initially this was an "exchange camp", where Jewish hostages were held with the intention of exchanging them for German prisoners of war held overseas.[2] The camp was later expanded to accommodate Jews from other concentration camps.
