Heraclea was an ancient city of Magna Graecia. The ruins of the city are located in the modern comune of Policoro in Basilicata. It was a Greek colony, but founded at a period considerably later than most of the other Greek cities in this part of Italy. The foundation of the city is placed by Diodorus in 432 BCE. It became famous as the site of the first major battle of the Pyrrhic War in 280 BCE in which king Pyrrhus of Epirus defeated a Roman army on the head of a coalition of Southern Italian Greek city states.
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.
