The Dymaean Wall (Teichos Dymaiōn) or Kalogria Castle is a prehistoric acropolis in western Achaea, Greece. The fortress stands in a strategic position on a rocky hilltop, north of the Prokopos lagoon, near the village of Araxos. It was built in the Mycenaean period, probably around 1300 BC, but human occupation of the site started already around 3500 BC. It was deserted in the 18th century AD. During World War II it was used by occupying Italian forces, who built a number of military installations on the site and damaged the prehistoric fortifications.
It was named the Dymaean Wall after the nearby ancient city of Dyme. During the war between the Achaean and the Aetolian Leagues (220–217 BC) it was seized by king Philip V of Macedon.
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.
