In the Roman times the city of Peqin was known by the name of Clodiana, an Illyrian-inhabited territory. The foundations of the castle are thought to date from the Roman period, the time of the construction of the Via Egnatia. Its walls at one point had a height of around 12 metres. The castle was later rebuilt and expanded during the Turkish occupation of Albania, at which time it was passed into the control of the Sipahi (lord) of the local fief, who added a palace and a harem. The last resident of the castle was Demir Pasha.
The castle was equipped with subterranean tunnels which served as exits several km away from the city in difficult times. Similarly, clay pipes have been found in the walls of the castle, which archaeologists believe is an indication that water was supplied from outside the castle during wartime.
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.
