Kassel is home to the 38th UNESCO World Heritage site in Germany: Wilhelmshöhe Park was added to the famous list of world cultural and natural heritage sites on 23 June 2013. The UNESCO World Heritage committee paid tribute to Wilhelmshöhe Park as a unique baroque fusion of art, technology and architecture.
The landscaping of Wilhelmshöhe Park began in 1696 on the initiative of Landgrave Karl of Hesse-Kassel. Covering 240 hectares, it is Europe's biggest hillside park and includes numerous sights such as the fountains, Wilhelmshöhe Palace, the great Hercules statue and the artificial ruins of Löwenburg Castle.
Wilhelmshöhe Park joins five other UNESCO World Heritage sites in Hessen: Lorsch Abbey, the Roman Limes and the boundary of the Roman Empire, the Upper Middle Rhine Valley, Messel Fossil Pit Site and Kellerwald-Edersee National Park, part of the World Natural Heritage Ancient Beech Forests.
