Alytus mound is the only preserved witness of the foundation of the town and it dates probaly from the 11th century. It is said that a wooden castle was standing here in the 14th century that was burnt down later by the Teutonic Order. The detailed route to Alytus castle is described in Teutonic “The Description of Lithuanian Roads”, this castle defended the main roads to Trakai and Vilnius from crusaders.
An impressive panorama of the town opens from the mound, while its foot is decorated by an exposition of sculptures “Ancestors of Alytus Mound”.
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.
