Museum
Geymüller Castle

In Vienna's 18th district, Währing, stands the Geymüllerschlössel, a small castle with an architectural blend of Gothic and Oriental elements. Built at the beginning of the 19th century, it now serves as a museum for the living culture of the Empire and Biedermeier periods.
History+
The castle was erected in 1808 and is named after its builder, Johann Jakob Geymüller. The building's architecture combines Gothic and Oriental stylistic elements. The Geymüllerschlössel changed hands multiple times. Later owners included Johann Heinrich von Falkner-Geymüller, whose lifestyle earned it the nickname “Verschwender-Villa” (Spendthrift Villa) and possibly made him the model for Ferdinand Raimund's play “Der Verschwender.” From 1888, it belonged to the textile industrialist Isidor Mautner, until it was mortgaged to the Austrian National Bank in 1929 due to economic difficulties.
