Matrera Castle was built in the 9th century by Omar ibn Hafsún to defend Iptuci, the most advanced city of the Cora de Ronda. However, Mount Pajarete was a place of human settlement since Antiquity.
In the 13th century, it was conquered by San Fernando, who rebuilt it. Nevertheless, at the beginning of the XIV century, it returned to Muslim hands, being definitively reconquered by Alfonso XI in 1341. However, being located in the middle of the Moorish Border or Band was besieged by the Muslims of Granada in 1408 and in 1445.
By 2010, only a few walls of the castle remained standing, and the ruins were further damaged by rain in 2013. A restoration project was launched in 2010 and completed in 2015. Parts of the tower were rebuilt with lime plaster similar to samples found on the site, with large, plain blocks defining the original shape of the castle.
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.
