Eufemio Castle is mentioned in several historical sources, the oldest dating back to the first decades of the 12th century. It was described as an important place for the old town, thanks to its strategic position. In the 13th century, the importance of the Eufemio Castle grew considerably, as it was one of the main ones imperial castles of the reign of Frederick II of Swabia, whose guards guarded him during the battle against Muslims, who resided near the historic Segesta.
In the following centuries, the Eufemio Castle was inhabited by the various feudal lords who took turns at the command of Calatafimi Segesta, up to the 19th century, where it was used as prigione. Eufemio Castle remained in operation until 1868, only to be totally abandoned to itself, causing its state of degradation which, over time, saw the collapse of many of its parts. Today it is partially restored.
The Eufemio Castle would have been equipped with three towers, two still visible today in its remains, while there is no trace of the third, a fate shared also with the walls who would have wrapped it up to improve its defense system. Once you entered the Eufemio Castle, on the left there would have been the prisons, some walls of which have still been left engravings made, in all probability, by the prisoners themselves while serving their penalties. The Eufemio Castle would also have had a upper floor, which would have been used as a residence for the reigning feudal family.

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.
