Gabersee is notable for its psychiatric hospital that was used for an euthanasia programme during Nazi Germany and was used as a post-World War II displaced person camp in the American sector before it reopened in 1953 resuming normal activity.

[1] After the Second World War during the American occupation zone, the clinic was used as a displaced persons camp for Jewish survivors.

Here, and in another former euthanasia camp in Attel (today another borough of Wasserburg) around 2000 Jewish persons from Poland, Hungary, Romania and Czechoslovakia were housed between 1946 and 1950.

Although the camp was under de-jure control of the United Nations Relief and Rehabilitation Administration (UNRRA), the US-Government gave it so much sovereignity that it functioned as a de-facto independent municipality.

[2] After the military occupation of Germany ended, the camp ceased operations in 1950 and most of the jews moved to the US, Canada, Australia or Israel, the most popular destination, despite being only created two years ago.

Today, as part of the kbo-Inn-Salzach-Klinikum, it stands as a leading institution in psychiatry, psychotherapy, psychosomatic medicine, geriatrics, and neurology.
