Palais Schwarzenberg is a Baroque palace in front of Schwarzenbergplatz, Landstraße, the 3rd district of Vienna, Austria. It is owned by the princely Schwarzenberg family.
Construction started in 1697 under the architect Johann Lucas von Hildebrandt and finished with alterations in 1728 under Johann Bernhard Fischer von Erlach. Construction was supervised by master builder Anton Erhard Martinelli.
The palace was commissioned by the Obersthofmarschall Heinrich Franz Graf von Mansfeld and Prince von Fondi, but he died while the Palace was being built. The unfinished property was finally bought in 1716 by Prince Adam Franz of Schwarzenberg, who had it completed.
