Schadau Palace is situated in the Schaudaupark, and was built between 1846 and 1854 according to the plans of Pierre-Charles Dusillon in the Gothic Revival style, for the banker Abraham Denis Alfred de Rougemont
Since 1925 the castle has belonged to the city of Thun and contains a restaurant and the Swiss Gastronomy Museum. Between 1972 and 1992 the façade of the castle was renovated by the city's own quarrymen.
The oldest known surviving panorama was completed in 1814 by Marquard Wocher, and is on display at the Schadau Castle, depicting an average morning in the Swiss town of Thun. As of today it's owned by the Gottfried Keller Foundation.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
