Located inside the former Frauenbad (Women’s Bathhouse) near the tram terminus, this interesting museum showcases the work of its namesake Arnulf Rainer, who was born in Baden in 1929. A recalcitrant art-school dropout, he began painting in a surrealist style before developing his idiosyncratic multimedia and performance works.
This includes the infamous painting with chimpanzees episode where Rainer attempted to mimic the work of a number of painting apes only to be chased by one of his unwilling collaborators. The museum has retained the delightful marble features of the Biedermeier bathhouse from 1815, making it all the more worth a visit. Exhibitions change twice a year.
