Forces Motrices

The Bâtiment des Forces motrices, French for "Power plant building", is the power house of a former hydro power plant and waterworks in Geneva called Usine des Forces Motrices, later Usine des Forces Motrices de la Coulouvrenière.

The structure is positioned near the point where the River Rhône flows out of Lake Geneva towards Lyon. It was created between 1883 and 1892 to exploit the flow of the river to provide water pressure to feed the city's water supply and a hydraulic power network. Furthermore, the weir of the structure was designed to regulate the level of the lake.
