Built around 1060, the Château de Lormont probably saw Eleanor of Aquitaine stay here during her marriage to King Louis VII of France. The Prince of Aquitaine, also known as the Black Prince lived there. The archbishops of Bordeaux possessed the château in the 14th century. In 1453, negotiations to end the Hundred Years War also took place there. After having been successively destroyed and rebuilt, notably in 1626 by architect Henry Roche for the Cardinal Francis d'Escoubleau of Sourdis then to his brother Henri de Sourdis. The castle became national property in 1789.
Today the castle is private property. After a major renovation it was converted to house offices and also a restaurant.
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.
