World Map at Lake Klejtrup

The World Map at Lake Klejtrup is a miniature world map built of stones and grass in Klejtrup Sø near the village of Klejtrup, Viborg Municipality, Denmark.

In 1943, Søren Poulsen, a local farmer, was working on the drainage of the surrounding meadows when he found a stone shaped like the Jutland peninsula. This inspired him to create a small world of his own. During the winter months, with the use of primitive tools, he placed big stones carefully on the ice. When spring arrived, the stones could easily be tilted into place, and in this way the World Map took shape. Some of the stones used weighted more than 2 tonnes.
