The Hadamar Euthanasia Centre (German: NS-Tötungsanstalt Hadamar), known as the "House of Shutters", was a psychiatric hospital located in the German town of Hadamar, near Limburg in Hessen, from 1941 to 1945.Beginning in 1939, the Nazis used this site as one of six for the T-4 Euthanasia Programme, which performed mass sterilizations and mass murder of "undesirable" members of German society, specifically those with physical and mental disabilities. In total, an estimated 200,000 people were murdered at these facilities, including thousands of children. These actions were in keeping with the eugenics ideas about racial purity developed by National Socialist ideologues. While officially ended in 1941, the programme lasted until the German surrender in 1945. Nearly 15,000 German citizens were transported to the hospital and murdered there, mostly in a gas chamber. In addition, hundreds of forced labourers from Poland and other countries occupied by the Nazis were murdered there. Hadamar and its hospital fell within the American occupation zone after the war. During 8–15 October 1945, United States forces conducted the Hadamar Trial, the first mass atrocity trial in the years following World War II. They prosecuted doctors and staff on charges of murdering citizens of allied countries, namely, forced labourers from Poland and other countries. The US had jurisdiction for these crimes under international law. Several people were convicted and executed for these crimes. After the German courts were reconstructed under the occupation, in 1946 a doctor and nurse were prosecuted by Germans for the murders of nearly 15,000 German citizens at the hospital. Both were convicted. The hospital continues to operate. It holds a memorial to the euthanasia murders as well as an exhibit about the Nazi programme.
