The cemetery was built for the near Pitkäniemi mental hospital. Total of 426 patients were buried to the cemetery between 1902-1964 before it was abandoded. Because the human dignity of mental patients was not very high 100 years ago, only small tombstones or no tombstone att all were added to graves. The chapel was burned down more than half century ago.
There are also some remains of old trenches near the cemetery. Those were built by the Russian army during the First World War to defence Finland against the potential occupation of Germany.
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.
