A tour of L'Argentière-La Bessée on the trail of its industrial heritage&hellipNothing less than an open-air museum!

This trail takes you back in time! The route is punctuated by landmarks offering an insight into the history of hydroelectricity and the town's industrial past: compressors, water turbine, wagon, aluminium bar; the rich past of L'Argentière in a nutshell!

Description

Setting out from the Tourist Information Office of L'Argentière-La Bessée, follow the banks of the Durance towards the red bridge.

  1. When you come to the red bridge, cross it and then take the narrow footpath on the left. 
  2. Turn left and make a there-and-back detour to see the arch bridge: go past a garage to reach a promontory which takes you close to the bridge, and then retrace your steps. Carry on, passing the former Péchiney factory, and then take the Rue de l'Industrie where there is an exhibition of photographs on the walls.
  3. Turn right at the roundabout and cross the road to read the information panel on the Francis water turbine. Carry on towards the railway bridge and go under it through an underpass, to reach the explanatory panel about the Mines du Fournel wagon. Retrace your steps back to the Francis turbine panel and continue straight ahead, past the mobile compressor. At the next roundabout, go right to the impressive aluminium bar. 
  4.  From the aluminium bar, cross the road heading towards the station, to discover the shunting locomotive. Go back to the main road of L'Argentière-La Bessée and carry on towards the town hall ("Mairie"). After admiring the enormous ice-pick in front of the town hall, carry on towards the bridge which takes you across the Durance and back to the Tourist Information Office.

  • History

    The vertical compressor

    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. 

  • History

    Louis Leprince-Ringuet and L'Argentière

    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.

  • History

    The Péchiney factory

    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. 

  • History

    Former industrial area of L’Argentière-la-Bessée

    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.
  • History

    The Francis turbine

    The American James Francis developed the Francis turbine between 1849 and 1855. It is a “àreaction” turbine suitable for medium-sized waterfalls (with a water head of between 15 and 500 metres). The water enters the turbine and then circulates between the turbine blades, which are fixed, while the inner wheel is mobile. The pressure at the wheel intake is greater than the pressure at the outlet. 

  • History

    The mobile compressor

    In the mines, compressed air is used to remove dust and to create power for the drills. The mobile compressor holds compressed air in a resistant tank. This is brought to a high pressure via a pump (the compressor). The compressed air is then distributed to the mine machinery through a conduit system.

  • History

    The giant aluminium bar

    A young metal, aluminium is the most abundant metallic element on earth. Today, the aluminium industry is the second biggest after steel. 

    This enormous ingot was made in L'Argentière-La Bessée. 

  • History

    The light rail tractor

    A locomotive? No, its little cousin, the light rail tractor. This replaced manually pushed carts and horse-drawn vehicles. Less powerful than a locomotive, it travelled along narrow-gauge tracks which could be laid on different types of terrain. An information panel also described the role of this vehicle during the Great War.

  • History

    The old workers' housing districts

    Workers' housing districts were built to house the many workers who were employed at the Péchiney factory. These districts have now been demolished. The architecture of the houses varied according to the status of the employee. A town hall, a cinema, a bandstand and churches were also constructed.
