Crossing the Vénéon, this superb stone humpback bridge dates back to the seventeenth century. It is an example of the know-how of our forebears, and the fact that this substantial project was undertaken at all is an indication of the importance of this valley. This bridge also constitutes built evidence of the age-old human occupation of the La Lavey valley. The arch of this bridge was restored in 1972. The structure was decrepit and the joints were completely re-grouted. As you cross the bridge, note the colour of the water of the Vénéon. This is due to fine particles in suspension, the result of erosion of the glaciers in the upper reaches of the Vénéon and dissolved silica from the feldspars contained in the crystalline rocks.
