Hartheim

In 1940, the Hartheim Castle in Austria was converted into a Nazi euthanasia facility for the Aktion T4 program. Between 1940-1944, the Nazis sent patients deemed mentally or physically disabled, prisoners from nearby concentration camps, and civilian forced laborers to the facility, where they were killed.
