Fuensaldaña Castle construction started in the 13th century, but it is not until the 15th century that the structure acquires today's configuration. It was built by the Vivero family. The family became linked to the region's history when the future Catholic Monarchs got married in their castle.
Inside, the building was shaped as a 'U' around the cortyard, which today has been made into the parliament floor. During the Comunidades war, it was peacefully occupied by the comunero troops. The castle was the General Assembly of Castilla y León.
Inside the keep are four vaulted halls out of ashlar masonry. The keep, like the curtain walls, is also equipped with round towers at its corners, two nice turrets and battlements.
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.
