The Ducal Palace of Béjar was built after 1203 by Alfonso VIII. Although these already very reduced in the XIXth century, they still conserve some square and round towers and part of their perimeter bordering the oblong hill on which the old part is based. Béjar was a royal place, but with Enrique III, in 1396, it passed to the lordship of Diego López de Zúñiga or Estúñiga, whose successors will hold the title of dukes of that place, granted by the Catholic Monarchs.
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.
