Jerez de los Caballeros Castle dates back to the 13th century. The castle stands on the western part of a hill, around which the town of the same name extends. Since the Neolithic it was inhabited by Phoenicians, Celtic Betures, who were initially known as 'Ugultiniacum', Romans, Visigoths, Muslims and chivalric orders such as the Temple and Santiago settled chronologically in these territories.
The current castle was built by the Templars, who refused to lay down arms when the order was suppressed, and came to a sticky end. You can wander around at will, but it's basically just the impressive walls that are preserved, with pretty gardens dotted around.
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.
