Now the Sigmund Freud Museum in Vienna is located in Freud's former practice and spacious apartment in Vienna at 19 Berggasse. and covers his life story and the history of psychoanalysis. This house in Alsergrund was newly built when Freud moved here in 1891. The previous building on the site, once the home of Victor Adler, had been torn down. In 1938 Freud was forced to leave German-annexed Austria due to his Jewish ancestry, and fled to London. His old rooms, where Freud had lived for 47 years and produced the majority of his writings, now house a documentary centre to his life and works. The influence of psychoanalysis on art and society is displayed through a program of special exhibitions and a modern art collection. The Vienna museum consists of Freud's former practice and a part of his old private quarters. Attached to the museum are Europe's largest psychoanalytic research library with 35,000 volumes, and the research institute of the Sigmund Freud Foundation.
