In the location's words:

Wilhelmsthal Castle near Calden, not far from Kassel, is considered one of the most beautiful rococo castles in Germany. It was built in the 18th century under Landgrave Wilhelm VIII and originally served as a summer residence and hunting lodge. The palace is surrounded by an extensive park with lakes, watercourses, visual axes and staffage structures that are typical of rococo garden design. The elegantly furnished interiors with original furniture, fine stucco ceilings and precious wall coverings are particularly worth seeing. Today, the castle is a popular excursion destination for culture and nature lovers - a place that combines baroque splendor and idyllic scenery.
