The model for the Hercules of Kassel was the so-called Farnese Hercules, a monumental statue of Greece over 3 m high. Sculptor's Lysipp, handed down as a Roman copy of the marble sculptor Glykon, in the National Archaeological Museum of Naples.
The Hercules is a copper statue of the Greek demigod Heracles (Latin: Hercules, Germanized Hercules) in the mountain park Wilhelmshöhe in Kassel (North Hesse, Germany). It is 8.25 m in size. The statue, which is regarded as a landmark of the city of Kassel, is located at the top of a pyramid standing on the Octagon, the Giant Castle. Today, the name "Hercules" stands not only for the statue, but also for the entire building, which is also the starting point of the summer water features in the Bergpark. The Octagon and the Hercules go back to different construction phases. Since 23 June 2013, Hercules - as part of the Wilhelmshöhe Mountain Park - has been listed as an example of absolutist architecture in the UNESCO World Heritage List.
The castle-like Hercules was built between 1701 and 1717 according to designs by the Italian Giovanni Francesco Guerniero. The entire complex, including the cascades before the Hercules after the client, Landgrave Karl von Hessen-Kassel, also bears the name Karlsberg and under this term is a Baroque aspect and the western conclusion of the Wilhelmshöhe mountain park, both spatially and historically.
