The L’Argentière-la-Bessée green route ("Voie Verte")

In 1910, a 22-year-old engineer, Gilbert Planche arrived in L'Argentière-La Bessée to take advantage of the water here and open a large aluminium factory. The vertical compressor is the forerunner of the pneumatic drill. The mine operators needed a large quantity of coal and compressed air helped to accelerate coal output. In 1852, Swiss physicist Jean-Daniel Colladon invented the pneumatic drill. The vertical compressor enabled the production of compressed air which powered a drill and simplified coal excavation. The compressor is placed vertically on its support, hence its name. 

Louis Leprince-Ringuet was the director of the Physics Laboratory of X ("X" being a polytechnic school in Villeurbanne) established in L'Argentière. During the summer of 1942, he took in several Jewish students, thus saving them from the Nazis and deportation to Auschwitz. A panel presents the discoveries made by Louis Leprince-Ringuet in this laboratory. A text by Bernard Lévi is also displayed. As a young Jewish student, he took part in research at the laboratory during the summer of 1942. In it he thanks the scientific team for helping him to escape the anti-Semitic barbarism.

This French electro metal company established itself in L'Argentière in 1907. The construction of the aluminium factory started in 1909 and it opened its doors in 1910, powered by the electricity plant built by Gilbert Planche. With it, L'Argentière became an industrial town. The economic crisis of the 1970s and the rise of foreign sources of supply led to the factory's closure in 1985. It was partially demolished in 1988. The workers left the town and in order to prevent the abandonment of L'Argentière, a restructuring project was launched. 

On the two walls of these now-disused industrial structures, you can read the history of L’Argentière-la-Bessée. The town is marked by its industrial past, in particular by the presence of a hydroelectric power station built between 1907 and 1909 to harness the power of the mountain waterfalls. At the time, it was the most powerful power station in Europe. Other industries were also established here, like the Société du Quartz Fondu fused quartz works and the aluminium factory which provided livelihoods for a large number of workers.

The Durance is the biggest river in Provence. Its source rises in the municipality of Montgenèvre at an altitude of 2,390 metres, and it flows down to meet the Rhône to the south of Avignon. This is a "pluvio-nival" river, that is to say, its flow depends on the natural addition of water due to snowmelt and rainfall. It thus constitutes a real playground for kayakers from across Europe.

The source of the Fournel rises in the Fournel valley, in the heart of the Parc National des Écrins, and flows into the Durance near the white water stadium. It is known as a high alpine canyon offering lots of sport and leisure possibilities, and is the most popular in the Haut Val Durance. It is ideal for an introduction to vertical activities, in particular thanks to the presence of several jumps, toboggan runs and rappel sites. Access is authorised from April to October and is regulated because it is located upstream from an EDF water intake, which presents a real hazard.

As part of its restructuring after the closure of the industrial site, the town of L'Argentière-la-Bessée opted for sports tourism, exploiting the natural elements present on the site, that is to say, water. Standing at the beginning of the longest navigable section of the Durance river, in 1993 the municipality decided to establish itself as a major white water centre by creating this stadium which covers a 400-metre stretch. So thanks to its reputation and its ideal situation, every year this stadium hosts several elite competitions at national and international level.
