The Winterpalais des Prinzen Eugen is a Baroque city palace built for Prince Eugene of Savoy, the military commander whose grander summer residence became the Belvedere. Its rooms are a reminder that Vienna's aristocratic life was not confined to the big garden palaces outside the old centre.
The building later served state offices and has been used for exhibitions tied to the Belvedere. Even if you only pass by, the facade adds a fine Baroque note to a walk through the Innere Stadt.
