The two runic stones at Jelling (12 km/7 mi northwest of Vejle) with drawings and inscriptions, have provided considerable historical information. The smaller, which Gorm set up for his wife, bears the inscription, "Gorm the King set up this monument to Thyra his Queen, the pride of Denmark". Harald Bluetooth (940-85), the son of Gorm, embraced
Christianity; he had the mound on the south erected over a pagan cult site and set up the larger runic stone. On the latter is written, "This stone was erected to the memory of Gorm, his father, and Thyra, his mother, by Harald Bluetooth, that Harald who won for himself Denmark and all Norway and who made the Danes Christian". Harald transferred his seat from Jelling to Zealand, probably to Roskilde.
Between the graves and the runic stones a small church stands on the site where Harald Bluetooth had previously built a wooden church (11th C.), which was later altered on several occasions. In the present church can be seen copies of Romanesque wall-paintings by Magnus Petersen (1875); in the choir are modern paintings by J. T. Skovgaard.
