The Winter Palace of Prince Eugene (German: Winterpalais Prinz Eugen), also known as the City Palace (German: Stadtpalais), is a high-Baroque palace in the Innere Stadt district of Vienna, Austria. Located on a narrow street at Himmelpfortgasse 8, the palace was used as the winter residence of Prince Eugene of Savoy, who spent his summers at the Belvedere. The Winter Palace was designed and constructed by Johann Bernhard Fischer von Erlach from 1695 to 1700, and by Johann Lukas von Hildebrandt from 1702 to 1724 following his predecessor's plans.
The palace was acquired through auction by Empress Maria Theresa for the imperial court in 1738, along with most of the prince's other buildings. In 1752, the palace was converted by Nicolò Pacassi into the seat of various state institutions. The palace housed the Finance Ministry of the Austrian Empire from 1848 to 1918 and the dissolution of the Habsburg Empire. Since 1919, the palace has housed the Federal Ministry of Finance. From 2007 to 2013, the palace was extensively renovated. The Winter Palace of Prince Eugene is considered "one of the most magnificent Baroque edifices in Vienna".
In 1694 and 1695, Prince Eugene of Savoy purchased several old houses on Himmelpfortgasse in Vienna, including an early Baroque theater. In 1695, Johann Bernhard Fischer von Erlach won the prestigious and lucrative contract to build a palace at this location for the prince. In 1697, Fischer von Erlach began constructing the seven-bay palace, and by 1698, painters were already working on the ceiling frescoes. Fischer von Erlach's construction manager was Andrea Simone Carove. The stonemasonry was done by the Viennese master Johann Thomas Schilck. The large portal with side reliefs—Hercules fighting the giant Antaeus on the left, and Aeneas saving his father from burning Troy on the right—was sculpted from Kaiserstein by Lorenzo Mattielli. During this first phase of construction, the remarkable staircase with Kaiserstein steps and the Atlas figures were completed. The sculptures from Zogelsdorfer stone in the stairway were executed by Giovanni Giuliani. Material deliveries were made by master Reichardt from Moenchhof Fux.
