Hellig kilde – ’holy spring’. In Norse folklore and legends, springs were endowed with magical powers. Three holy sources e.g. sprung from the Nordic tree of life, Yggdrasil. In the Middle Ages, visiting holy and miraculous springs became popular; and many of the spring names were inspired by the pagan god names such as Odin, Tor and Freja. Individual as well as collective journeys to holy springs were taken; some of the collective ones even turned into festivals or fairs. A holy spring was indeed considered a mythological place.
