The construction of the Marmionda Castle dates back to the 12th century, shortly after the beginning of the invasion of Al-Andalus by the Almohads (1147), who ended the Almoravid empire. In 1167, it was conquered by the Christian king of León, Fernando II, who handed it over to the Order of the Temple. Almost thirty years later, in 1196, it was recaptured by the Almohads. In 1213, it was definitively reconquered by Alfonso IX of León, who gave it to the Order of San Julian del Pereiro, later known as the Order of Alcántara.
From Visigothic times to the Middle Ages, there was no better defensive element for the inhabitants of the Alagón Valley than this castle. It was a strategically well-positioned fortress, south of Coria and on the way to Cáceres, with a prior passage through the Tajo River valley. Throughout its history, various reforms took place, with the 16th century being the last of some importance. It was abandoned from the second half of the 17th century.
It is of a square base and consists of the following elements: a pair of circular towers, the keep on the northeast side, and a second tower on the northwest side that was recently reconstructed and restored but whose aesthetics disrupt the overall harmony of the ensemble; large walls (curtains) crowned with crenellations with pyramidal tops; a barbican in front of the wall; an extensive courtyard; and a large cistern.
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.
