« King Harald ordered this monument in memory of Gorm, his father »
Harald Bluetooth, Runic inscription on the large Jelling Stone, circa 965

The story that haunts this land

Your quest for the decree begins at the foot of Nordhøjen, Jelling's northern mound. Erected around 959-965, this mound, 65 meters in diameter and 8-10 meters high, was excavated in 1820, revealing it may have housed the tomb of Gorm the Old, Harald Bluetooth's father. As an archivist, you examine the surroundings, where the Jelling Monuments, classified as a UNESCO World Heritage site in 1994, attest to the importance of this site for the history of Jelling and Denmark. Augmented reality allows you to visualize the original burial structures, helping you understand Viking burial practices and the status of the rulers.

A few steps from Nordhøjen, you arrive at the Jellingstenene, the famous Viking runestones. The large stone, erected by Harald Bluetooth around 965, is the first to mention the name 'Denmark' and proclaims the Christianization of the country. Standing 2.42 meters high and weighing about 10 tons, it is an essential historical document. The small stone, erected around 960 by Gorm the Old in memory of Thyra, his wife, reveals the family ties of the early kings. Your mission drives you to decipher the runes, revealing the words carved by the Vikings who shaped the cradle of Denmark. These stones are the heart of Jelling's heritage.

Your journey then takes you to Jelling Kirke, Jelling Church, built of stone around 1100 on an earlier Christian site dating from 934. This church, with its 35-meter-high bell tower, had its interior restored in 2004, revealing 19th-century Neo-Romanesque frescoes. It is here that the tombs of Gorm the Old and Harald Bluetooth were believed to have been placed before being moved. As an archivist, you study the evolution of Christianity in Sjaelland, and how this faith replaced ancient Viking beliefs. AR tools show you the original structures and architectural evolutions of the edifice.

Continuing your exploration, you discover the Skibssætningen, a 67-meter-long ship-shaped stone setting, located south of the church. Built around the 10th century, contemporary with the mounds, this arrangement is visible in the UNESCO park. These structures are crucial for understanding Viking funerary rituals and the symbolism associated with ships. Augmented reality helps you visualize the size and scale of this stone ship, and how it integrated into the sacred landscape of Jelling, forming an integral part of the Jelling monuments.

Finally, your mission leads you to the Palisaden, a circular palisade reconstructed with 162 concrete pillars, demarcating a 12-hectare sacred site around the Viking monuments. This fortification, dating from the 10th century and rebuilt in the 1940s, offers a panoramic view of the entire complex. As an archivist, you understand the importance of this demarcation for the protection of Sjaelland's treasures and monuments. The Kongernes Jelling exhibition center, inaugurated in 2017, located at Parvis de Kongernes Jelling, Gormsgade 23, 7300 Jelling, offers an interactive exhibition on the Jelling Stones and the Viking history of Jelling, open Tuesday to Sunday from 10 am to 4 pm in 2026. You leave Jelling with a deep understanding of its central role in Denmark's history, an interactive visit that brought the runes and Viking kings to life.
