According to the legends, Al-Mansur (legendary Moorish leader) was defeated near Calatañazor Castle in a bloody battle against Christian troops in 1002. The fortress originally had two quadrangular towers on the corners and a keep. Later on, circular towers were added to the southern wall and semi-circular ones next to the main entrance. The current appearance dates mainly from the 14th century.
The castle is part of the walled village of Calatañazor but separated from it by a dry moat that was cut out of the rock. On the castle's irregular enclosure there are ruins of several towers and the keep, which is situated next to the entrance over the moat.
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.
