The castle of Salemi is one of the best preserved castles in Sicily. Inside, the library and the resurgence museum are housed. The castle has Norman origins and dominates the town with its trapezoidal shape and square, 20 meters high, corner towers, and a cylindrical tower.
The castle was built by Norman King Roger around 1077 to the site of Roman-Arab fort. Frederick II altered it in the 13th century.
In 1441, on December 11, in the castle of Salemi a confederation made up of Salemi, Trapani, Mazara, Monte San Giuliano and by the barons of Castelvetrano and Partanna was formed which undertook the defense, and bore the costs, of the Queen White and Royal House of Aragon. Salemi was, therefore, more fortified and garrisoned during the raids of the Turks.
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.
