Teutoburger Wald, Nordrhein-Westfalen
The Externsteine are among the most impressive natural monuments in Germany
The Rock formation is exciting, because their cultural-historical significance is still not fully understood. It is known that the mountain chain originated about 80 million years ago.
The Lower Cretaceous sandstone was placed vertically in the area of the Externsteine and since then shaped by erosion. Today, the stones can be climbed through two staircases. You should definitely go up, because you get from 40m height a great view of the Teutoburg Forest and the Wiembecketeich.
