The Luisenburg Rock Labyrinth is a felsenmeer made of granite blocks several metres across and is part of the Großes Labyrinth Nature Reserve near Wunsiedel in Germany. For a long time its formation was believed to have been caused by natural disasters such as earthquakes. Today it is known that processes such as weathering and erosion over a long period are much more likely to have been responsible for the formation of the rock labyrinth.
