Quart castle is a set of buildings arranged within a fortified perimeter, which respects the natural contour of a difficult rocky slope.The donjon (keep) standing on the highest point of the rock, the functional layout of individual buildings, the chapel and the winding passageways, are evidence of an early or Germanic fortified structure, although current architectural evidence point to more recent periods, as do the first narrative sources, which suggest its origins go back to the end of the 12th century (around 1185).
After the death of Henry of Quart in 1377, the castle and fiefdom went to the Savoys, who sold it to Philibert Laschis in 1550, who in turn sold it almost immediately to the Balbis. In the 17th century, the castle belonged first to Count Nicholas Coardo and then to the Perrone of San Martino, who gave it the Municipality of Quart in 1800.
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.
