Majdanek, or KL Lublin, was a German concentration and extermination camp built and operated by the SS on the outskirts of the city of Lublin during the German occupation of Poland in World War II.
 Although initially purposed for forced labor rather than extermination, the camp was used to kill people on an industrial scale during Operation Reinhard, the German plan to murder all Jews within their own General Government territory of Poland.
 The camp, which operated from October 1, 1941, until July 22, 1944, was captured nearly intact, because the rapid advance of the Soviet Red Army during "Operation Bagration" prevented the "SS" from destroying most of its infrastructure, and the inept Deputy Camp Commandant Anton Thernes failed in his task of removing incriminating evidence of war crimes.
 Therefore, Majdanek became the first concentration camp discovered by Allied forces.
 Also known to the "SS" as "Konzentrationslager Lublin", Majdanek remains the best preserved Nazi concentration camp of the Holocaust.

The Częstochowa Ghetto was a World War II ghetto set up by Nazi Germany for the purpose of persecution and exploitation of local Jews in the city of Częstochowa during the German occupation of Poland.
 The approximate number of people confined to the ghetto was around 40,000 at the beginning and in late 1942 at its peak – right before mass deportations – 48,000.
 Most ghetto inmates were delivered by the Holocaust trains to their deaths at the Treblinka extermination camp.
 In June 1943, the remaining ghetto inhabitants launched the Częstochowa Ghetto uprising, which was extinguished by the "SS" after a few days of fighting.

The Białystok Ghetto (Polish: "getto w Białymstoku" ) was a World War II Jewish ghetto set up by Nazi Germany between July 26 and early August 1941 in the newly formed "Bezirk Bialystok" district of the Third Reich within Nazi occupied Poland.
 About 50,000 Jews from the vicinity of Białystok and the surrounding region were herded into a small area of the city, which was turned into the "Bezirk's" capital.
 The ghetto was split in two by the Biała River running through it "(see map)".
 Most inmates were put to work in the forced-labor enterprises for the German war effort, primarily in large textile, shoe and chemical companies operating inside and outside its boundaries.
 The ghetto was liquidated in November 1943 after the Białystok Ghetto uprising was crushed.
 All its inhabitants were either killed locally, or transported in Holocaust trains to the Majdanek and Treblinka extermination camps.
Auschwitz concentration camp (German: "Konzentrationslager Auschwitz" , ] , also "KZ Auschwitz " or "KL Auschwitz ") was a network of German Nazi concentration camps and extermination camps built and operated by the Third Reich in Polish areas annexed by Nazi Germany during World War II.
 It consisted of (the original camp), Auschwitz II–Birkenau (a combination concentration/extermination camp), (a labor camp to staff an IG Farben factory), and 45 satellite camps.
Bełżec (] , in German: Belzec ) was a Nazi German extermination camp built by the SS for the purpose of implementing the secretive Operation Reinhard, the plan to eradicate Polish Jewry, a key part of the "Final Solution" which entailed the murder of some 6 million Jews in the Holocaust.
 The camp operated from to the end of .
 It was situated about 0.5 km south of the local railroad station of Bełżec, in the new "Distrikt Lublin" of the semi-colonial General Government territory of German-occupied Poland.
 The burning of exhumed corpses on five open-air grids and bone crushing continued until March 1943.
Sobibór (or Sobibor , or , ] ) was a Nazi German extermination camp built and operated by the SS near the railway station of Sobibór during World War II, within the semi-colonial territory of General Government of the occupied Second Polish Republic.
 The camp was part of the secretive Operation Reinhard, which marked the deadliest phase of the Holocaust in German-occupied Poland.
 The camp was situated near the rural county's major town of Włodawa (called "Wolzek" by the Germans), 85 km south of the provincial capital, Brest-on-the-Bug (Brześć nad Bugiem in Polish).
 Its official German name was "SS-Sonderkommando Sobibór".
 Jews from Poland, France, Germany, the Netherlands, Czechoslovakia and the Soviet Union (including Jewish-Soviet POWs), were transported to Sobibór by rail.
 Most were suffocated in gas chambers fed by the exhaust of a large petrol engine.
 Up to 200,000 people were murdered at Sobibór and possibly more.
 At the postwar trial against the former "SS" personnel of Sobibór, held in Hagen two decades into the Cold War, Professor Wolfgang Scheffler estimated the number of murdered Jews totalled a minimum of 250,000.
 This would make it the fourth worst extermination camp, after Bełżec, Treblinka, and Auschwitz.
The Umschlagplatz (German: "collection point or reloading point" ) was a holding area set up by Nazi Germany adjacent to a railway station in occupied Poland, where the ghettoised Jews were assembled for deportation to death camps during the ghetto liquidation.
 The largest such collection point consisted of a city square in occupied Warsaw next to the Warsaw Ghetto, used for several months during daily deportations of 254,000 – 265,000 Warsaw Jews to the Treblinka extermination camp.
 A monument was erected in 1988 on Stawki Street, where the "Umschlagplatz" was located, to commemorate the deportation victims.
 Another prominent example included the Radogoszcz station "Umschlagplatz" adjacent to the Łódź Ghetto where prisoners were brought under military escort for deportations directly to Chełmno (Kulmhof) and Auschwitz extermination camps.
