Château de Cornusson was originally a medieval castle first mentioned in 1157. It was rebuilt in the 16th-17th centuries by La Valette-Parisot family. It saw some action during the Wars of Religion and held out several times against Protestant forces.
The Vignes family from Puylaroque acquired the château by marriage in the late 17th century. Apparently, it was pillaged during the Revolution and left in a terrible state. After that, it passed through various hands and sank into the obscurity of rural French life.
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.
