The Hallwyl Palace was built 1893-1898 to the design of Isak Gustaf Clason for Count Walther von Hallwyl and his wife Wilhelmina. It was created to accommodate the office of the count and the extensive art collection of the countess. While the exterior of the building and the court is historical in style — borrowing architectonic elements from medieval prototypes and Renaissance Venice — it was technically utterly modern on its completion — including electricity, central heating, telephones, and bathrooms, while the elevator was a later addition.
The countess collected her artworks during her worldwide journeys in order to found a museum, and, consequently, the palace was donated to the Swedish State in 1920, a decade before her death. The collection encompasses some 50,000 objects, and the museum is still open to the public.
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.
