The Viennese City Park (German: Wiener Stadtpark) extends from the Parkring in the First District of Vienna up to the Heumarkt (a street, literally translated as hay market) in the Third District and is visited both by tourists and by native Viennese. The total surface area is 65,000 m².
Even as early as in the Biedermeier period, the glacis before the Karolinenstadttor (Caroline City Gate) was a popular site of entertainment. During the demolition of the city walls and the creation of the Vienna Ringstraße in its place, the mayor at that time, Andreas Zelinka, promoted the project of creating a public park on the territory. The park was designed in the style of English gardens by the landscape painter Josef Selleny, while the plans were made by the city gardener Rudolf Siebeck. On 21 August 1862 the park was opened, becoming the first public park in Vienna.

On the southern shore of the Wienfluß, the so-called Kinderpark (Children's park) was created in 1863, which is today still used mainly as a playground and for sports. The Karolinenbrücke (Caroline Bridge), which was built in 1857 (since 1918 it is known as Stadtparkbrücke - City Park Bridge) connects it to the Stadtpark proper on the northern side of the river. After the regulation of the Wienfluss, the whole river area was rebuilt by Friedrich Ohmann and Josef Hackhofer between 1903 and 1907, with a gate out of which the river flows, pavilions and stairs to its shorts. The architecture, together with the U-Bahn station by Otto Wagner, is among the sights of the park.
At the water glacis, a spa pavilion was built, in which mineral water with healing properties was served. The current Kursalon building was built between 1865 and 1867 according to plans of Johann Garben. The opulent building in the historicist style of the Italian renaissance is located next to the Johannesgasse.
