Tignes Dam, 180m/590ft high, overlooks the Isère River in the Tarentaise Valley. The massive post-War project was inaugurated in 1953, when it was the largest arch dam in Europe and it is still the highest dam in France. The dam is decorated by a huge (18,000m²/59,000ft²) fresco, the largest in the world, depicting a giant, although now partly faded. The dam formed Lake Chevril, which lies in a hollow surrounded by mountains.
