History of Denmark between 500 BC - 400 AD
The Early Iron Age in Denmark covers the period from 500 BC until 400 AD and is divided into three periods: Pre-Roman or Celtic Iron Age (500 - 1 BC), Early Roman Iron Age (1 - 200 AD) and Late Roman Iron Age (200 - 400 AD).
In the time around 500 BC people began to extract iron from local deposits. People were no longer dependant on bronze from distant areas of Europe. In addition, iron was a much stronger and more suitable metal for weapons and tools. The farmers in the Early Iron Age lived together in small, fenced villages. That it was not always peaceful and friendly though is testified by the weapon offering from Hjortspring Mose. You can also read more about the woman from Huldremose, who was laid in the bog dressed in her finest clothes.
A new metal, silver, appeared in the time around the Birth of Christ. The large silver cauldron from Gundestrup is a good example of this. At the same time the Romans invaded large parts of western Europe. The Roman Empire’s proximity led to significant cultural and social changes in Denmark. In the princely graves from Hoby and Himlingøje you can see the result of the meeting with the Roman Empire.

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.
