query: How many Nazi concentration camps were there in Poland?
passage: German camps in occupied Poland during World War II
German-occupied Poland contained 457 camp complexes. Some of the major concentration and forced labour camps consisted of dozens of subsidiary camps scattered over a broad area. At the Gross-Rosen concentration camp (to which Polish nationals were expelled from the annexed part of Poland) the number of subcamps was 97.[2] Under Auschwitz, Birkenau, and Auschwitz III (Monowitz) with thousands of prisoners each, the number of satellite camps was 48; their detailed descriptions are provided by the Auschwitz-Birkenau State Museum.[3][4] Stutthof concentration camp had 40 subcamps officially and as many as 105 subcamps in operation,[5] some as far as Elbląg, Bydgoszcz and Toruń, at a distance of 200 kilometres (120mi) from the main camp.[6][7]
passage: Catholic Church in the 20th century
In Poland, the Nazis murdered over 2500 monks and priests while even more were sent to concentration camps. The Priester-Block (priests barracks) in Dachau concentration camp lists 2600 Roman Catholic priests. Stalin staged an even more severe persecution at almost the same time. After World War II historians such as David Kertzer accused the Church of encouraging centuries of anti-Semitism, and Pope Pius XII of not doing enough to stop Nazi atrocities.
