The Castle of Fadrell is located in the municipality of Castellón de la Plana. It is a castle of Muslim origin, built between the 11th and 13th centuries.
The castle, with an irregular shape, consisted of four enclosures that adapted to the terrain in a stepped manner. In the upper enclosure is the Alcazaba with three semicircular towers, along with remains of walls and cisterns.
The intermediate enclosure, Albacar, which contains the former, has three more towers and houses the Hermitage of La Magdalena.
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.
