Reggio Calabria Castle was originally built before 540 AD and enlarged by the Normans and later by the Aragonese in 1459. Throughout the centuries it has been restored and enlarged by its conquerors.
The building began to decay in the very early 19th century. Various collapses and demolitions had dotted its history until the recent and radical restoration that brought it back to its original splendor. Today it is the seat of expositions and art exhibitions.
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.
