In the outskirts of Mtskheta are the ruins of Armaztsikhe fortress (3rd century BC). Armaztsikhe was the residence of the Kings of Iberia. This is one of the oldest cities of the Antique Era, which is not fully explored yet. It is also called like Georgian Acropolis. The Greek historian Dio Cassius mentioned this place in his book “The history of Rome”. He wrote that in 65 years BC, Roman Senator Gnaeus Pompeius invaded Iberia and reached this Acropolis too.
Archaeological investigations began in 1943 and three main cultures were identified: the oldest finds were dated to the 1st century BC to 2nd century AD, the central findings on the 3rd-5th centuries, and the latest to the 6th century. Consequently Armaztsikhe was destroyed by the Arabs in the 8th century. There are a royal sarcophagus, vestiges of the ramparts, a fortified tower and supporting pillars, foundation walls of the palace, a bath house, a wine cellar, a pre-Christian temple and a canal system.
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.
