Trujillo Alcazaba was built originally the 12th century. The city changed hands several times between Christians and Arabs in the 12th century and was finally conquered by Fernando III in 1233. The castle was reformed after Reconquista and again in the 15th century.
Surviving years of abandonment, the French invasion, the Carlist War, the Republic and the Civil War, the Castle is the center of Trujillo’s life. It was declared a historical-artistic monument in 1925 and acquired by the city council in 1929. The last reforms that were made were the construction of a first chapel to house the stone image of the city’s patroness saint in 1546, and later, in 1951, the demolition of such chapel to build a larger one inside between the two main towers (albarran towers), from where the image of the Virgin remains today looking towards her town.
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.
