From 5th to 12th august 2006, an international working camp took place close to the Frinds of Nature house “La Serment” at La-Chaux-de-Fonds in Switzerland, during which young Friends of Nature revitalized a drying stone wall. The activity was covered by media, and thus contributed to the creation of awareness and regional identity in the Jura. 16 juveniles from Hungary, France, Germany and Switzerland took part in the event.
