The castle of Villar Dora is a medieval feudal residence, among the best preserved of the Susa valley. It was built in the 13th century to the rocky hill which has been occupied since Roman times. The castle was renovated in Gothic style in the 14th century by Provana family. In the early 20th century, Count Antonielli d'Oulx carried out restoration works that returned the original medieval aspect to the central body of the castle.
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.
