Anundshög is the largest tumulus in Sweden. It has a diameter of 60 metres and is about 9 metres high. Assessments of the era of the mound vary between the Bronze Age and the late Iron Age. A fireplace under it has been dated by radiocarbon dating to sometime between AD 210 and 540.
Some historians have associated the mound with the legendary King Anund, while others regard this as speculative. It is purported also that the name is taken from the large runestone at the site, the central stone in a row of 15 alongside the mound, re-erected in the 1960s and apparently marking out the route of the Eriksgata. The inscription on the runestone reads: "Folkvid raised all of these stones after his son Heden, Anund's brother. Vred carved the runes."
At the foot of the mound are 2 large stone ships placed end to end, 51 metres and 54 metres long. The site was a thing-place and the ship settings may be associated with this function.
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.
