Miranda del Castañar Castle, or at least the tower of homage, was probably built by Pedro de Zúñiga. By means of a small enclosure that serves as a gate, the tower is attached to another D-shaped tower and other remains that might belong to a previous fortress. The round loopholes are the usual 15th-century artillery loopholes.
Miranda was founded around 1215.The well preserved wall probably dates from that time. Prior to the death of Diego de Zúñiga, the fortress is taken by García Alvarez de Toledo, the Duke of Alba, who claimed to be entitled to have it.
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.
