Jelling is a historical site located in Denmark, known for its significant Viking Age monuments. It features two large burial mounds and two runestones, which are considered some of the earliest examples of written Danish history. The site is often referred to as the "birthplace of Denmark" due to its connection to the unification of the Danish kingdom. The larger of the two runestones, known as the Jelling Stone, was erected by King Gorm the Old in the 10th century. It commemorates his wife, Thyra, and marks the transition from paganism to Christianity in Denmark. Today, Jelling is a UNESCO World Heritage site, attracting visitors interested in Viking history and culture.
