On June 23, 2013, the Commission of the United Nations Educational, Scientific and Cultural Organization in Phnom Penh, Cambodia, decided to include the Wilhelmshöhe Mountain Park in the List of World Cultural and Natural Heritage sites to be included. The approximately 560-hectare World Heritage site is the first mountain park in the world to receive this honor. UNESCO thus recognizes the facility as an outstanding and unique example of European architectural and garden art.
The origins of the design date back to the 1680s. The park extends from the monumental Hercules building over the 350-meter-long cascade system down to Wilhelmshöhe Palace and beyond. The garden artistically designed facility is considered one of the largest in Europe and forms a unique cultural monument.
