The Royal Tobacco Factory, an 18th-century industrial building was, at the time it was built the second largest building in Spain, second only to the royal residence El Escorial. It remains one of the largest and most architecturally distinguished industrial buildings ever built in that country, and one of the oldest such buildings to survive.
Since the 1950s it has been the seat of the rectorate of the University of Seville. Prior to that, it was, as its name indicates, a tobacco factory: the most prominent such institution in Europe, and a lineal descendant of Europe's first tobacco factory, which was located nearby. It is one of the most notable and splendid examples of industrial architecture from the era of Spain's Antiguo Régimen.
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.
