The first written mention of Íscar was in the year 939 AD in Muslim chronicles. The remaining Christians reconquered Iscar in 1086 AD. Build on the ruins of its ancient fortress, Iscar’s Castle stands majestic looking over the village. The oldest preserved parts of this fortress (probably dating back to the 13th century) are remains of the curtain wall and the inside structure of the tower. To provide a defence against possible attacks from the west side, weak point, the enclosure was re-enforced in the second halfof the fifteenth century for defensive purposes.
At the back of the Main Tower, a large defensive spur, flanked by two turrets transformed the ground floor into the shape of a pentagon.In this side also a new body was added as a defensive barbican, with a small artillery barrier with three circular barrel turrets. And for safety a Moat was dug into the limestone rocks whose access was by a drawbridge.
On one of these turrets appears the shield of Pedro de Zúñiga y Avellaneda and his wife Catalina de Velasco y Mendoza, IICounts of the Miranda del Castañar, which dates this work at between 1478 and 1493.
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.
