The scenic Freisaal Castle dates from the Middle ages. The oldest record of the building dates back to 1392. The name is derived from 'Freudensaal', meaning 'pleasure hall'. Its original purpose was just that: to serve as a pleasure castle for Prince Archbishop Pilgrim II. von Puchheim. Ernst von Bayern re-modelled the building in 1549.
A fundamental change in the building′s structures was caused by construction work done in 1907, which transformed Freisaal Castle into a somewhat messed up villa. However, frescos in the second floor by Hans Bocksberger the older from 1558 remained preserved, one of the paintings showing Prince Archbishop Michael von Kuenburg moving into Salzburg. Today, Freisaal Castle is private property and is not open to the public.
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.
