Schloss Hartheim, also known as Hartheim Castle, is a castle at Alkoven in Upper Austria, some 14 kilometres (9 mi) from Linz, Austria. It was built by Jakob von Aspen in 1600, and it is a prominent Renaissance castle in the country. The building became notorious as one of the centers for the Nazi killing program known as Action T4, in which German citizens deemed mentally or physically unfit were systematically killed with poison gas. After the end of Action T4 (August 1941), these killings were extended to include Jews, Communists and others considered undesirable by the state who were imprisoned in concentration camps. These people stem from various countries in the world. In this capacity it was known as the Hartheim Killing Facility. In sum 30.000 people (18.000 people with handicaps and mentally ill people, about 12.000 concentrations camp prisoners and forced laborers) were killed in Hartheim until the end of the year 1944.
