Jelling is one of Denmark's most important historical sites. In 1994 the monuments were included on UNESCOs list of historical monuments particularly worthy of preservation, the World Heritage List (thus joining among other things Stonehenge and the Great Wall of China).
In the tenth century, at the highest point in the landscape west of Vejle, the kings Gorm the Old and Harold Bluetooth created a monument that is unique in the Nordic context. The oldest feature is the remains of a huge ship-shaped stone circle - then came the rune stones and the mounds, and finally the church.
Gorm the Old's rune stone links the royal couple Gorm and Thyra to a kingdom called Denmark. The story continues on Harold Bluetooth's rune stone, which describes a central event in the history of Denmark: the King's acceptance of Christianity on behalf of his whole people. For that reason the stone is often called "Denmark's Certificate of Baptism".
