Bergpark Wilhelmshöhe, Kassel, Germany (UNESCO)

The Mountain Park Wilhelmshöhe in Kassel, Germany is the largest hillside park in Europe and second largest in the world. Construction began in the late 17th century under the rule of the Landgraves of Hesse-Kassel. Its completion took about 150 years. Originally it was laid out in the Baroque Style and later changed into an English landscape garden.
In 2013 it was added to the UNESO World Heritage list.
