Trevejo Castle origin dates back to before the 12th century when a Muslim fortress stood in its place, serving as the basis for its construction in the 15th century. The original fortress was conquered by Alfonso VII of León, who handed it over to the Order of the Temple. In 1184, by order of King Fernando II of León, it passed into the hands of the Order of St. John of Jerusalem. Two years later, the same monarch decided to give it to the Order of Santiago. Over the course of history, it also came to belong to the Order of Alcántara.
During the French invasion of the peninsula, the castle was destroyed to prevent Spanish guerrillas from taking refuge in it.
Today, the homage tower and a large part of the wall still resist the passage of time. At the foot of the castle, there are a series of anthropomorphic stone tombs, allegedly containing the remains of some of the warrior monks who were initially owners of the castle.
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.
