Baeza is a city and municipality of Spain belonging to the province of Jaén. It is now principally famed for having some of the best-preserved examples of Italian Renaissance architecture in Spain. Along with neighbouring Úbeda, it was added to UNESCO's list of World Heritage Sites in 2003.
Established in the Roman times, the sixteenth century was the golden era of Baeza (and nearby Úbeda). It grew rich from several industries, notably textiles, and the noble families, which were well connected with the Spanish Imperial state. They hired major architects of the era to design the present cathedral, churches, public buildings, and private palaces in the then-fashionable Italian style. The town's university building dates to 1533. The city declined in importance in the seventeenth century, with the only remaining industry consisting of local production of grain and olive oil. As few newer structures were built during this period, this had the effect of preserving the town's Renaissance legacy.
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.
