19 Berggasse, Alsergrund, is the former residence and office of Sigmund Freud. It was Freuds home from 1891 until his flight to England in 1938, and is currently the site of the Vienna Sigmund Freud Museum. Most of the patients Freud treated during the development of his theories, of psychoanalysis, visited him at his Alsergrund office.
In addition, the park in front of the Votivkirche, on the corner of Währingerstrasse and Schottenring, was named after Freud, in memory of his frequent visits there.
