Jelling Runestones

The Jelling Runestones erected in the 10th century are very important to the Danes. They represent the founding act of the nation.

One of the two stones relates the conquest of Denmark and Norway as well as the conversion of the Danes to Christianity.

The Jelling Runestones are two 10th-century runestones in Jelling, Jutland. They are the most important stones in Danish history and were erected on the initiative of Kings Gorm and Harald Bluetooth. The Great Jelling Stone contains a depiction of Christ and an animal.The stones lie near two burial mounds (the older one dates from 958/59), between which Jelling Church was built around 1100. The entire ensemble was declared Denmark's first UNESCO World Heritage Site in 1994.

Here is some information in German:
The town of Jelling [ˈjɛleŋ] or Jellinge [ˈjɛleŋə] is located in central Jutland, northwest of Vejle. Royal Jelling is one of Denmark's most important archaeological sites. Between Denmark's largest burial mounds (North and South mounds) lies a stone church from around 1100 AD, which was built over older wooden churches. In front of it are the Thyrastein and the Haraldstein. The ensemble of church, burial mounds and rune stones was declared a World Heritage Site by UNESCO in 1994. The square has had cult significance since the Bronze Age. Not far from Viborg is Mammen, where an ornamental ax inlaid with silver wire, appropriate to this period, was found. But it was 10th century kings who gave Jelling its importance today.

The outline of the approx. 350 m long stone ship surrounded by stone steles is impressive. The original ship can no longer be made out without the enclosure.
