The Gold Hall was used as the Duke’s throne room. The golden stucco decorations on the background of two-coloured stucco marble, made by Johann Michael Graff, create a glamorous atmosphere indispensible for an audience hall. The ceiling painting, made by Francesco Martini and Carlo Zucchi, depicts the apotheosis of Duke Ernst Johann.
The White Hall was initially designed as a chapel, but in the second construction period it was transformed into a ball-room. The stucco decorations on the walls depict different pastoral scenes as well as the four seasons and four elements of the world.
The Grand Gallery served as a banqueting hall were tables were laid within the court’s reception hours. It took fourteen years to restore the ceiling painting, whereas the work on the wall painting was discontinued in 1992 and was only resumed in 2010.
The Small Gallery displays Rastrelli’s early style as it has retained its appearance from the first construction period. Initially, the Small Gallery was planned as an antechamber to the chapel.
The Oval Porcelain Cabinet completes the staterooms. Forty-five rocaille consoles support a collection of Chinese and Japanese porcelain vases.
