At the Oberalp Pass at 2,044 meters, not only is the obligatory "passport photo" waiting at the Oberalp Pass sign, but also the only lighthouse in the Alps. It comes from Rotterdam, where the original lighthouse can be found in the Maritime Museum, which once stood in Hoek van Holland, at the mouth of the Rhine into the North Sea - thus completing the circle from the source to the mouth.
