Pont Coppet

Pont Coppet is a stone bridge built in 1626 that spans the gorge of the Fier river on the boundary between the villages of Sales and Vallières in Haute-Savoie, France. A single powerful arch stretching 22.5 metres carries its narrow, 4-metre-wide roadway high above the water, and today the same crossing that once bore carts and armies welcomes walkers and cyclists.

Who built the bridge, and why here?

The bridge was commissioned by Charles Emmanuel I, Duke of Savoy, who in the early 17th century wanted a shorter, more direct route between Chambéry and Geneva. Cutting straight across the Fier gorge at this point avoided a long detour through Rumilly, shaving several kilometres off the journey — a gain that mattered for both trade and military movement across the duchy. The year 1626 and the carved Savoy coat of arms still mark the stonework of the arch, alongside gargoyles designed to drain rainwater and stone wheel-guards meant to protect the parapet from cart axles.

What history has this bridge witnessed?

The best-known moment in the bridge's history came in March 1629, when French troops led by King Louis XIII and Cardinal Richelieu crossed it — a passage tied to the broader conflict over the succession of Mantua. For more than two centuries afterward, Pont Coppet remained the principal crossing on the Chambéry–Geneva road, carrying trade and military traffic between Savoy and Geneva.

Why did the bridge stop being the main route?

Pont Coppet's role as the region's key crossing ended when a new road was built through the Val de Fier valley in the 1860s, culminating in the opening of the Mottet bridge in 1864, which offered an easier, wider passage for growing wheeled traffic. From that point the old stone bridge gradually faded from the main transport network, though it was never abandoned — locals kept using it as a pedestrian shortcut across the gorge.

What should visitors know before going?

Erosion of the foundations set into the gorge's rocky walls eventually threatened the bridge's stability, prompting a thorough restoration between 2001 and 2002. Its historical and architectural value was formally recognised when Pont Coppet was listed as a French historic monument in November 2015. Today the bridge is fully open to pedestrians and cyclists, and the view down into the Fier gorge from its parapet is striking in any season. It makes a worthwhile stop for anyone exploring the Rumilly and Albanais area, pairing a short walk with a solid dose of local history.
