The town hall was originally built as a church in the 15th Century. During the reformation in the 16th Century Gustav Vasa gave the church to the people of Arboga and its new purpose was to be the town hall. However the king used the house as his own private residence instead. His daughter, Cecilia, Countess of Arboga, also lived here in 1570. From 1640 to the present day Arboga’s town council has had offices here. The present appearance dates from the renovation made in 1725-1759.
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.
