Saint Germain castle in Montjovet played an important part in the history of Val d’Aosta. Few traces remain of its original structure and its construction date is not known for certain. At the end of the 13th century, the Savoy became the owners, replacing the Montjovet family. As already happened in Bard, in this case too, the pretext was provided by the abuse of power that Feidino Montjovet acted on villagers and wayfarers. The castle was later sold to the Challant family but returned to the Savoy in 1438, when Amadeus VII installed a garrison there, which remained active until 1661, when it was transferred to the fortress in Bard, leaving Montjovet castle open to decay.
References: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.
