Lysá nad Labem was firstly mentioned in the Chronica Boemorum, with its existence mentioned in 1034. In the 13th century, a castle was built here and until the reign of the Luxembourgs, the town was property of the Czech queens. Since 1291, there has been evidence of Lysá being a town. In that year, Queen Judith of Habsburg issued a charter to unite the settlements of the Lysá estate into one economic unit.
During the Hussite Wars the town suffered a lot. At the turn of the 15th and 16th century, the Smiřický family of Smiřice rebuilt the dilapidated castle into a late-Gothic castle. In 1548, Emperor Ferdinand I added Lysá to the intimate dominion as a hunting centre. After a large fire, he had the castle rebuilt in the Renaissance style.
The sustainable development of the town was stopped by the Thirty Years' War. In 1647, Lysá was acquired by the empire general Johann von Sporck and then the town began to flourish. After the general's death, his son Franz Anton von Sporck began to reign. He made the most important changes in 1696 when the Augustinian monastery was restored and the new parish church and the Chapel of Three Kings were built.
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.
