Landgrave Karl von Hessen-Kassel had the octagon ("Giant Castle") with the figure of Hercules built between 1700 and 1717 by the Italian architect Giovanni Francesco Guerniero as the crowning glory of the 1.5-kilometer-long cascade complex.
A steep pyramid rises above the octagonal base, crowned by an 8.20 m high statue of Hercules. The work of the Augsburg goldsmith Johann Jakob Anthoni is a replica of the ancient Hercules Farnese.
