Scientific and technical heritage at La Norma
So-called "white coal" comes down from the glaciers and is used to power hydroelectric plants and generate energy from torrents. Water also powers the turbines at ONERA (Office National d'Etudes et de Recherche Aérospatiale), the giant wind tunnels where model airplanes and rockets are tested.
Discover how hydroelectricity works "from torrent to current" with guided tours of the Avrieux EDF power station.
Another scientific curiosity and technical feat is the Chappe telegraph, the forerunner of telecommunications. After a short hike through the mountain pastures, the Chappe telegraph at Courberon offers an exceptional panoramic view of the valley, and it's easy to understand why this part of the optical communication line linking Paris to Venice was installed here.
