When Monturque Castle was exactly built is unknown. Archaeological findings suggests it was built during the reign of the Ummayad Caliphate (661–750 AD) on Roman remains.
The Castle was conquered by Ferninand III in 1240, and for a long time thereafter its ownership passed intermittently between the Crown and Nobility. One early record of this is from 1273, when half of the Monturque tower was awarded by Martin Sanchez to his grandson, Lope.
The well-preserved tower, Torre del Homenaje, stands in the center of the Patio de Armas. A sober and simple structure, this tower was the best equipped of the castle to house its guests, who would probably only spend short stays here, as it does not show signs of having been adapted for permanent accommodation. The castle and tower are located on Calle de Rafael de Lara.
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.
