Old railway viaduct. Was never equipped with a rail, then submerged by the dam.

Lake Serre-Ponçon, located on the border between the departments of Hautes-Alpes and Alpes-de-Haute-Provence, is the largest artificial lake in mainland France and the second largest in Europe. Created by a huge dam in the 20th century, it offers turquoise waters, sunny beaches and a rich history. Explore the Muséoscope du Lac to discover how the dam was built and transformed the landscape and the lives of the inhabitants.
