Arzviller, France - 09 24 2023: On a pole along the former Marne-Rhine Canal (Canal du Marne au Rhin) in the lock keeper's valley (Vallée des Éclusiers) in Lorraine hangs a sign with various route indications for walking, hiking and cycling tours. The Canal du Marne au Rhin fell into disuse after the construction of a new canal and a boat lift (Plan ecliné de Saint Louis Arzviller). Lock keeper's house No 2 is out of focus in the background.
