A big chunk of perforated rock. The perforations are about 2000 years old. When the Romans discovered the Sea of Rocks (Felsenmeer) in the Odenwald they immediately saw its value and started to use the granite for their building projects. Since smaller chunks are easier to transport than huge rocks they started to work on the stones there and then in the middle of the forest. And sometimes they abandoned their work.
