The Schlosshotel Bad Wilhelmshöhe Conference & SPA is situated right at the heart of a glorious landscape – the UNESCO World Heritage Site Bergpark Wilhelmshöhe. As Europe's largest landscape park, the Bergpark Wilhelmshöhe is unlike anything else in the world. It covers an area of 240 hectares and merges into the Habichtswald nature park. Part of the mountain park - 100 hectares - is also home to some renowned spa gardens. The Bergpark Wilhelmshöhe, with its breathtaking and unique water art and features, became a UNESCO World Heritage Site in June 2013.
In place of the former hunting lodge of Maurice, Landgrave of Hesse-Kassel, one of the last large buildings of absolutism was constructed during William IX's reign, the classicistic summer residence of Schloss Wilhelmshöhe (1786–98), which today ranks among the most attractive museum sites in Germany. Nowadays, the central block of the palace is used as an art museum. Here you can find, among other things, painting collections from the "Old Masters", including world-famous pieces by Rembrandt and Dürer.
In addition to the summer palace, the Löwenburg (1793–1801) was also constructed during William IX's reign. Today, it is seen as one of the most important examples of the continent's neo-Gothic ruin architecture, home to valuable, medieval, early modern and romantic features and layout.
This replica of the ancient statue of Hercules Farnese reigns supreme atop the building, standing 8.25 metres tall and designed using copper sheet, the first colossal figure of the modern era north of the Alps. It was the model for later monuments such as the Hermann Monument and the Statue of Liberty. The visitor platform, measuring 28.5 m in height, can be accessed by stairs.
At the foot of the Hercules, water art provides for a stunning spectacle every year. The cool water gushes down through the cascades, the Steinhöfer Wasserfall, the Teufelsbrücke, and flows via the aqueduct down to the palace pond, where it reaches its final destination at the Große Fontäne, whose natural pressure makes the water shoot 52 metres into the air. This unique work of art is to become a World Heritage Site.
North of the residential palace, directly opposite the Schlosshotel, you find the Ballhaus, or ballroom building, built originally as a theatre (1808–09) during the reign of King Jérôme, an early work by architect Leo von Klenze. This building hosts special exhibitions of the Kassel state museums during the summer months.
