The Karlevi Runestone, designated as Öl 1 by Rundata, is commonly dated to the late 10th century. It is one of the most notable and prominent runestones and constitutes the oldest record of a stanza of skaldic verse.
The runic inscription on the Karlevi Runestone is partly in prose, partly in verse. It is the only example of a complete scaldic stanza preserved on a runestone and is composed in the "lordly meter" the dróttkvætt. It is notable for mentioning Thor's daughter Þrúðr and Viðurr, one of the names for Odin, in kennings for "chieftain." In the second half of the stanza a reference is made to Denmark, but it is not clear what exactly this means in this poetic context.
The stone is contemporary with the Battle of the Fýrisvellir and it is consequently possible that the stone was raised by warriors who partook in it, in memory of their lord. The inscription, which is on a granite stone that is 1.4 meters in height, is classified as being in runestone style RAK. This is the classification with inscriptions with runic text in bands that have no attached dragon or serpent heads and the ends of the runic bands are straight. The non-runic inscription on the reverse side appears to be accompanied by a small Christian cross and a Norse pagan Thor's hammer, or Mjöllnir.References:
Varberg Fortress was built in 1287-1300 by count Jacob Nielsen as protection against his Danish king, who had declared him an outlaw after the murder of King Eric V of Denmark. Jacob had close connections with king Eric II of Norway and as a result got substantial Norwegian assistance with the construction. The fortress, as well as half the county, became Norwegian in 1305.
King Eric's grand daughter, Ingeborg Håkansdotter, inherited the area from her father, King Haakon V of Norway. She and her husband, Eric, Duke of Södermanland, established a semi-independent state out of their Norwegian, Swedish and Danish counties until the death of Erik. They spent considerable time at the fortress. Their son, King Magnus IV of Sweden (Magnus VII of Norway), spent much time at the fortress as well.
The fortress was augmented during the late 16th and early 17th century on order by King Christian IV of Denmark. However, after the Treaty of Brömsebro in 1645 the fortress became Swedish. It was used as a military installation until 1830 and as a prison from the end of the 17th Century until 1931.
It is currently used as a museum and bed and breakfast as well as private accommodation. The moat of the fortress is said to be inhabited by a small lake monster. In August 2006, a couple of witnesses claimed to have seen the monster emerge from the dark water and devour a duck. The creature is described as brown, hairless and with a 40 cm long tail.
