The history of Herttoniemi Manor dates back to the 16th century. The Herttoniemi area is probably named after Laurens Hertoghe who might have been the first owner of the manor. The heyday was in the late 1700’s, when the manor was owned by Augustin Ehrensvärd. He led the construction of Suomenlinna fortress.
The present main building originates from the beginning of 19th century, when the manor was owned by admiral Carl Olof Cronstedt. The old porcelain factory was changed as the new main building and the park was established around it.
Today Herttoniemi park is an artistically unique milieu. The combination of baroque and English garden is one of the greatest in Finland. The main building functions as a manor museum and the park is open to the public. There is also an old old farm brought from Sipoo which is an outdoor museum.
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.
