Near the border stone 111, the official Kilometre Zero of the Western Front, there was a wooden observation post of the Swiss army during the First World War. This Poste d'observation N°2 offered a view of the French and German lines, while Switzerland maintained its neutrality 1. The post was a symbol of the tense calm at this unique border location, where three armies followed each other closely. Today, the site has been partly reconstructed and forms a special historical point along the hiking and cycling path in the far south of Alsace.
