Biskops-Arnö was a palatial residence of the archbishop of Uppsala, built in the first half of the 1300s. After the Reformation it was left to decay and finally demolished in the early 1700's, when the present main building was erected. For nearly 200 years Biskops-Arnö was a seat of Colonel in the Royal Regiment.
In 1956 Biskops-Arnö moved to the foundation of the Association of the Nordic Institute, who placed there a Nordic education institute and a college. Biskops-Arnö is a great destination that offers both nature and culture. Make sure to visit the Gothic hall, a room with limestone player and grand pillars - a remnant of the old bishop's castle. Visiting groups can book a meal or coffee at Biskops-Arnö college who also have hostel during the summer.
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.
