Jelling is a small town located in the southern part of Denmark, known for its historical significance as the site of two large burial mounds and two runestones that date back to the Viking Age. The Jelling stones are considered to be Denmark's most important historical monuments and are regarded as a symbol of Denmark's conversion to Christianity in the 10th century. The larger of the two stones is also known as the Jelling Stone, or the Gorm Stone, after King Gorm the Old, who is believed to have been buried in one of the mounds. The smaller stone, called the Harald Stone, commemorates Gorm's son, Harald Bluetooth, who is credited with uniting Denmark and introducing Christianity to the country. Together, the Jelling stones provide important insights into the cultural and religious changes that occurred in Denmark during the Viking Age.
