The garden parterre is still a visible feature of the French garden. As part of the transformation of the entire castle grounds by Sckell it was simplified, but retained its original size. The "Grand Cascade" was built by Joseph Effner in 1717. He was referring to a concept of François Roëttiers. The water falls in the middle of a two-part water staircase, the first stage being half round to the west, the second, deeper, is formed to the east. The cascade consists of symmetry which continues through the centre channel. The right side of the cataract was covered with pink marble in 1770. Originally a supporting architecture was to be provided, which was never executed. Instead, from 1775 to 1785, sculptures were added. Many were the work of Dominik Auliczek and Roman Anton Boos, who later added twelve decorative marble vases with mythological themes.
