One of the largest rocks of Nordic Bronze Age petroglyphs in Scandinavia is located in Tanumshede locality, Tanum Municipality. In total there are thousands of images called the Tanum petroglyphs, on about 600 panels within the World Heritage Area. These are concentrated in distinct areas along a 25 km stretch, which was the coastline of a fjord during the Bronze Age, and covers an area of about 51 hectares. Tanumshede rock carvings have been declared as a World Heritage Site by UNESCO.
Scandinavian Bronze Age and Iron Age people were sophisticated craftsmen and very competent travelers by water. (Dates for ages vary with the region; in Scandinavia, the Bronze Age is roughly 1800 to 500 BCE) Many of the glyphs depict boats of which some seem to be of the Hjortspring boat type carrying around a dozen passengers. Wagons or carts are also depicted.
Other glyphs depict humans with a bow, spear or axe, and others depict hunting scenes. In all cases the pictures show people performing rituals. There is a human at a plough drawn by two oxen, holding what might be a branch or an ox-goading crop made of a number of strips of hide.
The rock carvings are endangered by erosion due to pollution. To the dismay of some archaeologists, some have been painted red to make them more visible for tourists.
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.
