Auschwitz was a complex of over 40 concentration and internment camps. It was by 1942 the largest Extermination camp in the Nazi empire. It was a major site in the “Final Solution” the Nazi plan to murder European Jews. Auschwitz is broken down into 3 main camps Auschwitz-I, Auschwitz-II, and Auschwitz-III with many sub-camps surrounding them. Auschwitz has become a symbol of terror all over the world and visiting the massive complex today is a reminder of an almost unthinkable past.

The Dachau concentration camp was set up just weeks after Adolf Hitler had been appointed Reich Chancellor in 1933. The camps were set up to hold “political Prisoners” but quickly developed into a forced labor camp and grew in size to over 100 sub-camps. The camp was used as a model for all other Nazi forced labor camps, It was also used as a “school of violence” for the SS Nazi forces. 200,000 people were imprisoned here from 1933 until the American liberation in 1945. After the war, the camp served various purposes including an American Military base until 1965 when it became a memorial.

The Sachsenhausen Concentration camp was the closest to the Nazi capital of Berlin and held prisoners that the Third Reich wanted dead. The camp operated from 1936 until the end of the war in 1945. The camp was then reused by the Soviets from 1945 -1950 who also committed crimes against humanity at the camp. The camp is now a memorial open to visitors and also acts as a research center.

Terezin is a former Military fortress that turned into a concentration camp under Nazi occupation of Czech lands. In 1939 the Prague Gestapo Police prison was set up in the fortress and later in 1941, a Jewish ghetto was created. The camp was not built as an extermination camp but the conditions lead to over 33,000 deaths with many prisoners later being transported to the Mauthausen Concentration Camp. The Czech government retained a military garrison on the site until 1996. When the fortress was decommissioned and abandoned. However, in 1994 a permanent exhibition was installed and today the site is a memorial, museum, and also acts as a research center.

The Treblinka camp was located in the forest east of Warsaw. It operated from 23 July 1942 until 19 October 1943. The camp was made and used for operation Reinhard a deadly phase of the “final solution.” The Nazi plan was to exterminate Polish Jews in the General Government district of German-occupied Poland. In the 16 months of operation, it is estimated that between 700,000 and 900,000 Jews were killed in its gas chambers. A larger estimation than any other Nazi Concentration camp outside of Auschwitz. After the war, in 1959 the Polish Government set up a large stone memorial consisting of over 17,000 stones. Later in 1964, Treblinka was declared a national monument of Jewish martyrdom. Today, there is an exhibition center at the camp and it is a branch of the Siedlce Regional Museum. You can visit the official Museum website here.
