Santiago del Arrabal was built in 1245-1248 at the orders of Sancho II on the site of an older church and a mosque that is known to have been used since 1125. Many characteristics of the mosque have remained in the present building which is built in the Mudéjar architectural style. The church is named after Saint James (Santiago) of the outskirts (Arrabal). The patrons of the church during its foundation were members of the Diosdado family, knight commanders of the Order of Santiago.
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.
