Sofiensaal
In May 1938, Richard Suchenwirth founded the NSDAP Austria section there. During the war, the venue was used to collect the Jews (who were later deported). The building was restored to its former glory by Carl Appel in 1948. In the 1950, DECCA installed the most modern recording studio in Europe in the rooms. The studio was used until the 1970s, to make recordings of the Vienna Philharmonic Orchestra, amongst others.
