Axel Oxenstierna palace in the Old Town of Stockholm was designed by architect Jean de la Vallée to Chancellor Axel Oxenstierna and the construction started in 1653. The palace became the headquarters for the 1668-1680 Swedish Central Bank and after a series of state institutional policy.
The palace is uniquely conserved in particular to the exterior. There are state historic building since 1935 and is one of the Swedish architectural art's most significant and well-preserved works.
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.
