Alanís castle has Arab origins. The town was conquered by Ferdinand III in 1249 and the castle was rebuilt in 1392. It has a hexagonal floor plan, with a tower and barbican, which has now disappeared. Its walls are 2.3 metres wide and 6.5 metres high, leaving only one access to the enclosure on the north side, from where the village can be seen.
Th castle was attacked by the French during the Napoleonic occupation, who dynamited one of its walls, the southwest one, and the ruins are still preserved today.
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.
