The former hospital of Altona was built between 1859 and 1861 with a castle like atmosphere. Despite manifold expansions (for example the 1927 created residential home for nurses) the hospital was given up in 1970, because of the new building in Othmarschen.

Nowadays the building complex is home of the “Staatliche Fachschule für Sozialpädagogik” (College of Social Pedagogy). Long floors and class rooms are on all three floors, in the first floor is also a 100 square meter large conference room and in the basement there is a canteen with an entry to the atrium and the park behind the building. In the former building of the residential home for nurses are especially rooms for music, handcrafts and art.
