Château d'Urtubie still belongs to the same family since its construction in 1341. Additions and improvements were carried out in the 16th and 18th centuries and the castle is today a historic monument, furnished and decorated with refinement .
The stones of Urtubie tell six centuries of history of the Basque Country . King Louis XI sejourned in the castle in 1463 and Louis XIV raised the domain to the status of viscounty in 1654. In the 19th century Soult then Wellington were known to the castle during the Napoléonic wars.
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.
