Château de Saint-Denis-sur-Loire dates originally from the early Middle Ages. It was enlarged in the 13th century and acquired by Philippe Hurault in 1341. It still belongs to the successors of Hurault family. The castle was again restored in the 18th century.
This place is very famous, thanks to its thermal mineral water resort from more than a thousand year. During the 16th century Catherine de Medici and Marie de Medici, Queens of France, visited several times there. The baths were restored in 1851 and bottled mineral water was brought also to Paris.
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.
