Schönbrunn Palace

Probably the most popular sight in Vienna and not without reason. The palace complex with the extensive park, which visitors and locals like to use for walking and jogging, is simply fantastic. The building is fascinating not only from the outside, but also from the inside. The splendor of the rooms in the former Habsburg residence is incredible. Even a color was named after the castle: the Schönbrunn yellow.

Schönbrunn Palace is the most popular attraction in Vienna.
Schönbrunn Palace, built in its present form in the 18th century as a summer residence for Archduchess Maria Theresa, has been in Hietzing, Vienna's 13th district, since 1892. Its name goes back to a saying attributed to Emperor Matthias. He is said to have "discovered" an artesian spring here while hunting in 1619 and exclaimed: "What a beautiful fountain".
From 1638 to 1643 a palace was built in this area as a residence for the second wife of Emperor Ferdinand II, Eleonora Gonzaga. However, this facility was badly damaged in the second Turkish siege of Vienna in 1683. In 1687, Leopold I commissioned his heir to the throne, Joseph I, to have a representative new building designed by Johann Bernhard Fischer von Erlach for the castle, which was then far from the city gates.
It was not until 1743 that the palace and park were remodeled and expanded in their present form by Nikolaus von Pacassi and Johann Ferdinand Hetzendorf von Hohenberg under Maria Theresa, known as Empress since 1745. The Baroque palace was the summer residence of the kings and emperors of the empire from the mid-18th century until the end of the Holy Roman Empire in 1806, and of the Austrian imperial family from 1804 until the end of the First World War. During this time, the palace was almost continuously inhabited by a court of several hundred people and became a cultural and political center of the Habsburg Empire. During the Austro-Hungarian monarchy it also became k. k. called Schönbrunn Palace.
Schönbrunn is the largest palace and one of the most important and most visited cultural assets in Austria. The castle and the approximately 160-hectare park have been part of the UNESCO World Heritage since 1996. A main attraction in the castle park is the oldest zoo in the world that still exists, the Tiergarten Schönbrunn (16 ha). The palace and park are among the main tourist attractions in Vienna.
