The Castle of Archidona was built by the Arabs in the 9th century and rebuilt by Alhamar, the first Nasrid king, in the 13th century. In 1462 Archidona was conquered by the Conde de Osuna, beginning to expand outside the walls to occupy the area it currently has. After the Christian conquest, the new population center and its most prominent urban representation in the Plaza Ochavada, the 18th century curious octagonal shape is established; in her red brick and white lime are combined.
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.
