Alkoven

The Hartheim killing centre (German: NS-Tötungsanstalt Hartheim, sometimes translated as "Hartheim killing facility" or "Hartheim euthanasia centre") was a killing facility involved in the Nazi programme known as Aktion T4, in which German citizens deemed mentally or physically unfit were systematically murdered with poison gas. Often, these patients were transferred from other killing facilities such as the Am Spiegelgrund clinic in Vienna. This was initially a programme of "involuntary euthanasia" permitted under the law ostensibly to enable the lawful and painless killing of incurably ill patients; these murders continued even after the law was rescinded in 1942. Other victims included Jews, Communists and those considered undesirable by the state. Concentration camp inmates who were unfit for work, or otherwise deemed troublesome, were also executed here. The facility was housed in Hartheim Castle in the municipality of Alkoven, near Linz, Austria, which now is a memorial site and documentation centre.

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 program known as Aktion T4, in which German citizens deemed mentally or physically unfit were systematically murdered with poison gas. After the official end of Aktion T4 in August 1941, the facility was used to murder Jews, communists, and other concentration camp prisoners under a program known as "Action 14f13". In this capacity it was known as the Hartheim killing centre, where the Nazis murdered a total of 30,000 people.

The Innbach is a river in Upper Austria with a length of approximately 59 km (37 mi). Its source is near Gaspoltshofen at the foot of the Hausruck hills and empties into the Danube at Wilhering. Its drainage basin covers 196 km2 (76 sq mi). After Gaspoltshofen, the Innbach passes the towns of Kematen am Innbach, Pichl bei Wels and Bad Schallerbach, at the mouth of the Trattnach. Near Eferding, it joins with the Aschach and a few kilometers later flows into the Danube downstream of the Ottensheim-Wilhering Power Station . Due to its high volume, many mills were once located along the Innbach. The Innbach is populated with many species of fish, among them: brown trout, brook trout, bullhead, minnow, grayling, gudgeon, rainbow trout, chub, barbel, roach, rudd, spirlin, perch, nase, dace, bleak, carp, bream, burbot, pike, zander, and catfish.
