Vestiges and Witnesses: Archaeological Finds from the Nazi Euthanasia Institution of Hartheim as Objects of Research and Education

In Hartheim Castle, more than 30,000 people became victims of National Socialist euthanasia programs. In the course of building the memorial at the end of the 1990s, numerous structural remnants of the killing institution were found. In 2001 several pits with structural elements, some human remains, as well as belongings of people murdered were found by chance in the former castle garden. This contribution establishes the meaning these items have for research, as well as considerations and discussions about the possibilities of presenting the vestiges in museum form and how to use the latter for teaching projects.
