Tiryns is a Mycenaean archaeological site in Argolis in the Peloponnese, and the location from which the mythical hero Heracles was said to have performed his Twelve Labours.
Tiryns was a hill fort with occupation ranging back seven thousand years, from before the beginning of the Bronze Age. It reached its height of importance between 1400 and 1200 BC, when it became one of the most important centers of the Mycenaean world, and in particular in Argolis. Its most notable features were its palace, its Cyclopean tunnels and especially its walls, which gave the city its Homeric epithet of 'mighty walled Tiryns'. Tiryns became associated with the myths surrounding Heracles, as the city was the residence of the hero during his labors, and some sources cite it as his birthplace.
The famous megaron of the palace of Tiryns has a large reception hall, the main room of which had a throne placed against the right wall and a central hearth bordered by four Minoan-style wooden columns that served as supports for the roof. Two of the three walls of the megaron were incorporated into an archaic temple of Hera. The site went into decline at the end of the Mycenaean period, and was completely deserted by the time Pausanias visited in the 2nd century AD.
In 1300 BC the citadel and lower town had a population of 10,000 people covering 20–25 hectares. Despite the destruction of the palace in 1200 BC, the city population continued to increase and by 1150 BC it had a population of 15,000 people.
Along with the nearby ruins of Mycenae, UNESCO designated Tiryns as a World Heritage Site in 1999 because of its outstanding architecture and testimony to the development of Ancient Greek civilization.
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.
