Interior The real alteration occurred in the interior, where seven guest rooms and two ballrooms were created. The building is a highpoint of the late style of
Frederician Rococo, even though the
Neoclassical style was already largely set as the prevailing taste of the period. The halls were designed by Johann Christian Hoppenhaupt. The guest rooms were decorated differently with
lacquered, painted, or inlaid cabinets, whose costly
inlays of native woods decorated the entire wall from the ceiling to the floor. For paintings, the guest rooms have views of Potsdam, which document the town's design under Frederick the Great and were specially commissioned for the guesthouse by the king.
The Jasper Room In the middle of the building, under the cupola, lies the largest room, the
Jasper Room. The ballroom's walls are decorated with red
jasper and grey
Silesian
marble. The same colors are found in the floor design. The ceiling painting
Venus mit ihrem Gefolge (
Venus with her Retinue) was created by
Johann Christoph Frisch. Decorated panels from both
antiquity and the 18th century were attached to the background of red jasper.
The Ovid Gallery The second, large ballroom, located in the eastern part of the New Chambers is the
Ovid Gallery, decorated in the style of French mirrored rooms. On the long side of the room is a mirror stretching almost to the ceiling, across from which, on the garden side, are French doors. Frederick asked for the walls to be decorated with gilded reliefs of the liaisons of the ancient gods, which had been told of by the
Roman poet Ovid in his
Metamorphoses. The room's rich decoration comes from the workshop of the sculptors and brothers
Johann David Räntz and
Johann Lorentz Wilhelm Räntz. ==Selected collection highlights==
