The New Chambers in Sanssouci Park, Potsdam, were constructed for King Frederick the Great of Prussia from 1771 to 1775. The building, which stands to the west of Sanssouci Palace, serves as a complement to the Picture Gallery, which lies to the east. Both buildings flank the summer palace.
The chambers replaced an orangery, which had been built at that site in 1745 on plans by Georg Wenzeslaus von Knobelsdorff and held the terraces' potted plants during the winter months. Ramps, on which the tubs were taken in and out, serve as reminders of the building's original use. Master builder Georg Christian Unger was commissioned to turn the orangery building into a guesthouse. The building's basic elements were left alone, as were its size and floor-to-ceiling french doors. The most obvious change was the addition of a cupola on the middle section. The similarities between the architecture of the New Chambers and that of the Picture Gallery are such that the both buildings can be mistaken for the other.
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 Frederican Rococo, even though classicism was already largely set as the prevailing taste of the period. 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.
In the middle of the building, under the cupola, lies the largest room, the Jasper Room. The ballroom's walls are gloriously 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 in 1774 by Johann Christolph Frisch. Decorated panels from both antiquity and the 18th century were attached to the background of red jasper.
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 wished that the walls be decorated with gilded reliefs of the liaisons of the ancient gods, which had been told by the Roman poet Ovid in his Metamorphoses. The room's rich decoration comes from the workshop of the Bayreuther sculptors and brothers Johann David Räntz and Johann Lorentz Wilhelm Räntz.References:
The Château de Chaumont was founded in the 10th century by Odo I, Count of Blois. The purpose was to protect his lands from attacks from his feudal rivals, Fulk Nerra, Count of Anjou. On his behalf the Norman Gelduin received it, improved it and held it as his own. His great-niece Denise de Fougère, having married Sulpice d'Amboise, passed the château into the Amboise family for five centuries.
Pierre d'Amboise unsuccessfully rebelled against King Louis XI and his property was confiscated, and the castle was dismantled on royal order in 1465. It was later rebuilt by Charles I d'Amboise from 1465–1475 and then finished by his son, Charles II d'Amboise de Chaumont from 1498–1510, with help from his uncle, Cardinal Georges d'Amboise; some Renaissance features were to be seen in buildings that retained their overall medieval appearance. The château was acquired by Catherine de Medici in 1550. There she entertained numerous astrologers, among them Nostradamus. When her husband, Henry II, died in 1559 she forced his mistress, Diane de Poitiers, to exchange Château de Chaumont for Château de Chenonceau which Henry had given to de Poitiers. Diane de Poitiers only lived at Chaumont for a short while.
Later Chaumont has changed hands several times. Paul de Beauvilliers bought the château in 1699, modernized some of its interiors and decorated it with sufficient grandeur to house the duc d'Anjou on his way to become king of Spain in 1700. Monsieur Bertin demolished the north wing to open the house towards the river view in the modern fashion.
In 1750, Jacques-Donatien Le Ray purchased the castle as a country home where he established a glassmaking and pottery factory. He was considered the French "Father of the American Revolution" because he loved America. However, in 1789, the new French Revolutionary Government seized Le Ray's assets, including his beloved Château de Chaumont.
The castle has been classified as a Monument historique since 1840 by the French Ministry of Culture. The Château de Chaumont is currently a museum and every year hosts a Garden Festival from April to October where contemporary garden designers display their work in an English-style garden.
