To the source of the Birs on an old Roman road.
"One beautiful morning in late autumn I decided to visit the famous Pierre Pertuis rock tunnel. There are many interesting facts to be discovered about the source of the Birs and its peculiarities. As I walk along the path, I come across information panels with texts of poets and writers, one of them Goethe, who had also passed by here at one point in the past. The texts were translated into dialect and are beautifully illustrated. Furthermore, the panels present geological facts and details about the origin of the rock tunnel, which all of a sudden appears before me, and about the Roman road of old times."
