Jelling Church, a Romanesque stone church built around 1100, is the fourth on its site and a key part of the Jelling UNESCO World Heritage Site, symbolizing the transition from paganism to Christianity in Denmark. Its history is intertwined with Kings Gorm the Old and Harald Bluetooth, who built the first wooden church on the site as a tomb for Gorm, which was later reburied under the current church. The church is known for its frescoes, including the 12th-century Romanesque frescoes found in the chancel.
