Orangerie

In the location's words:

The Orangery in Kassel is a magnificent baroque building and one of the city's most important landmarks. It is located in the heart of the Karlsaue state park, an extensive and idyllic park along the Fulda river. The Orangery was built in the 18th century on the orders of Landgrave Karl von Hessen-Kassel and was originally used to protect exotic plants such as orange trees in winter, hence the name "Orangery". Today, the building is a place for culture, science and recreation.
