The Vätteryd grave field, also known as Vätterydshed, dates from the Iron Age. The grave field consists of 183 menhirs, 15 stone ships - the largest 25 m long and 8 m wide - and 2 circles. Many of the stone ships are so damaged that all that remains are parts smaller than half the original size.
In the beginning of the 19th century, Vätteryd, with about 600 menhirs, was considered the largest grave field in Scandinavia. The research conducted between 1955 and 1957 made clear that the site had been a place of cremation burials. The grave goods found - such as bronze jewelry, glass and bronze pearls, and bronze wire - were taken to various museums in Stockholm.
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.
