Suddenly, out of nowhere, an interesting-looking, inscription-free metal sculpture appears at this intersection, where some extremely muddy forest paths meet. Hiking can only be recommended here in summer.Update: An almost identical sculpture has recently been erected in front of the Bentler Gallery in downtown Bonn!

I'm not sure about that... 🤔
But couldn't this sculpture be related to the "Sculpture Bank" in Remagen?

Art in the middle of the forest on a street lined with azaleas. Unfortunately without explanation.
