The Nazis murdered their victims at a wide variety of sites, including vehicles, houses, hospitals, fields, concentration camps and purpose-built extermination camps.

All the camps were located in the General Government area of German-occupied Poland, with the exception of Chelmno, which was located in the Reichsgau Wartheland of German-occupied Poland.
In the period leading to the Final Solution, Nazi Germany created eight major euthanasia extermination centers to carry out the systematic genocide of the disabled.
