The larger Jelling stone, raised by King Harald Bluetooth in the 10th century and located at Jelling in southern Denmark, bears an inscription that states Harald 'made the Danes Christian' and commemorates his parentage and achievements. The Jelling complex (two runic stones and associated burial mounds) is widely regarded as a key monument marking the transition to Christianity and the consolidation of royal power in Denmark during the Viking Age. The site is a UNESCO World Heritage Site because of its clear historical importance.
