Estepa castle was known in the Islamic period as Hisn Istabba, and was taken by Spanish king Fernando III on 15 August 1241.
The city walls that still surround the old town on the San Cristóbal hill were first built in the tenth century by the Moors, renovated by Almohad invaders in the twelfth, and again reconstructed when Estepa fell to the Christian Order of Santiago in the thirteenth century. The keep inside the walls was built against attacks from Granada in the fourteenth century, and at 26 metres offers sweeping views of the town and surrounding countryside.
A defensive tower built by Lorenzo Suárez de Figueroa, Master of Santiago, it carried out defensive and logistical functions, measuring 26 metres high by 13 metres wide. On clear days, you can see Sierra Nevada from the roof.
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.
