Näsby estate belonged to Uppsala archbishop in 1300s and in 1520s it was donated to Kristina Nilsdotter (Gyllenstierna). In 1571 it was acquired by Gustav Axelsson Baner. Originally built in the 1660s and designed by Nicodemus Tessin the Elder, the current Näsby Castle is located in the picturesque and natural setting of Näsbyviken. The castle was burned to the ground in 1897, but was rebuilt according to the original design on the initiative of Carl Robert Lamm and Dora Lamm who moved into the castle in 1905. Parts of the old castle garden still exist and are well preserved. Today Näsby is a conference center with a hotel and restaurant.
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.
