About 70 meters from the shore of Urk lies a massive boulder in the IJsselmeer. This boulder was transported from Scandinavia to Urk during the Ice Age. The stone holds significant importance for the people of Urk. According to legend, Urk children do not arrive by stork; instead, they come from this 'Ommelebommelstién'.
When a child is about to be born, an expectant father must row out to the stone and, upon payment, receive his child there. The legend adds a whimsical detail: boys are twice as expensive as girls. This charming tale is deeply ingrained in local folklore and highlights the unique cultural heritage of Urk. The ‘Ommelebommelstién’ serves as a symbol of the town's connection to its past and the enduring nature of its traditions.
