Saint-Guérin Dam

The Saint-Guérin Dam is a concrete arch structure that curves across a mountain valley in the Savoie region, creating a large water storage basin behind it. The curved design allows the barrier to withstand the immense pressure exerted by the stored water.

Construction was completed in 1961 as part of a larger hydroelectric development strategy for the Savoie region. The project responded to France's need for increased energy production in the decades following World War II.

The reservoir created by the structure became a landmark that shaped how locals relate to the alpine landscape around them. From the vantage point of the dam, you witness how infrastructure and nature coexist in this mountain region.

A walking path runs along the right edge of the lake and provides access to viewpoints where you can see both the structure and surrounding mountains. Visit on clear days to fully appreciate the views and the scale of the construction against the landscape.

Since 2015, the dam has been outfitted with specialized monitoring equipment that tracks how the structure responds to earthquakes and changes in water levels. This continuous observation helps engineers ensure the safety and stability of the construction over time.
