The Skopje Aqueduct is the only aqueduct in Macedonia, and one of three largest and well preserved in the former Yugoslavia.
The question of when the Skopje Aqueduct was built is unclear. There are three theories, it may have been built during the reign of Rome (1st century), during the reign of Byzantine Empire (reign of Emperor Justinian I) or during the reign of Ottoman Empire. According to this latest theory the aqueduct was built in the 16th century for the many Turkish public hamams.
This aqueduct was in use until the eighteenth century. Only about 386 meters with 55 arches of this structure of stone and brick remain.
References: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.
