The Karlsaue is located on the western bank of the river Fulda southeast of the city centre of Kassel, near the central Friedrichsplatz.
In the southwest the Karlsaue borders to sport facilities like the Auestadion and the ice skating rink.
The impressive historical park was created on an almost entirely flat terrain; it contains many man-made lakes, canals and fountains.
The main palace Orangerie was built by Landgrave Charles between 1654 and 1730 as an “exotic winter garden” until the beginning of the Second World War.
A botanical highlight is the “Siebenbergen” island, which was redesigned by court gardener Hentze in 1822.
