Bobastro is the ruins of an old castle in the Province of Málaga. The castle was of Roman origin, but rebuilt by Umar ibn Hafsun during his rebellion against the Caliphate of Cordoba in the 9th century.
There had been a structure at the site since Roman times. In 880 AD, Umar ibn Hafsun settled in the ruins of the old castle of Bobastro near Ardales, in which he incited the muwallads and mozarabs to join his cause against the unfair, heavy taxation and humiliating treatment they were receiving at the hands of Abd ar-Rahman II and his successors. The rebels constructed a church within the castle which lasted until the end of their autonomy on January 19, 928.
In 888 AD, Al-Mundhir of Córdoba was murdered at Bobastro by his brother Abdullah ibn Muhammad al-Umawi, who later succeeded him.
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.
