 The Hørdum stone was discovered in 1954 during trench work adjacent to the church in Hørdum.Before the historical significance of runestones and picture stones was understood, they were often reused as materials in the construction of roads, bridges, walls, and buildings.The image on the stone illustrates a legend recorded in the "Hymiskviða" of the "Poetic Edda", in which the Norse god Thor fishes for Jörmungandr, the Midgard serpent.
