Palais Wittgenstein, Renaissance Revival city palace in Wieden, Austria

The Palais Wittgenstein stood at Argentinierstraße 16 in Vienna's Wieden district, built 1871–73 by architect Friedrich Schachner in the Italian Neo-Renaissance style for a client named Franz Pranter. It served as the Vienna residence of the steel industrialist Karl Wittgenstein and his nine children, among them the philosopher Ludwig and the pianist Paul Wittgenstein. The building was demolished in the 1950s and replaced by a residential block.

Architect Friedrich Schachner designed the residence in 1873 for Franz Pranter before it was purchased by steel industrialist Karl Wittgenstein. The property changed hands and took on new importance under the ownership of Ludwig Wittgenstein's father.

The palace's name comes from the Wittgenstein family, who owned it from the late 19th century. Karl Wittgenstein, father of the philosopher Ludwig and the pianist Paul, retired at the height of his career to support the Vienna Secession and the Wiener Werkstätte, which in 1908 was commissioned to decorate the interiors. Hermine Wittgenstein lived there alone from the early 1930s until 1950.

The palace stood at Argentinierstraße 16 in Wieden until the Österreichische Länderbank bought it after 1945 and had it torn down in the 1950s; a residential building now occupies the site. Nothing of the palace remains to visit, but the address on the present Argentinierstraße can still be located.

Karl Wittgenstein, the owner and steel industrialist, stepped back from his career at its peak to dedicate himself to supporting artistic movements. From this palace, he financed important cultural initiatives including the Vienna Secession and the Wiener Werkstätte.
