Castillo de Bujalance was built in the 10th century during the Caliphate of Abd-ar-Rahman III. It is a clear example of Muslim military architecture in Al-Andalus. It subsequently underwent several modernizations, most recently in 1512, which were paid for by Queen Joanna of Castile.
It is rectangular in shape, measuring 59 metres north-south and 51 metres east-west. The castle's original name, 'tower of the snake', and the fact that it had seven towers, led to the current name of the city and its coat of arms. In 1963, the Ministry of Culture declared the site a Bien de Interés Cultural monument. Currently, its courtyard is used as a cultural space, which is in the process of being cataloging, restored and reconstructed. Highlights include the Festival of Theatre, Music and Dance (Nights at the Citadel) and Andalusian Dinner during the summer months.
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.
