Mountain land restoration collection

These photographs take us to the mountains and forests, streams and glaciers, landscapes and villages of the past, where we meet the inhabitants and the foresters. Most of the photographs come from the Archives Nationales.

This photographic ensemble comes from the former administration of the ENEF. It was produced in the context of a large-scale policy on the restoration of mountain land (RTM).It is an outstanding collection of several thousand photographs relating to the work undertaken in the mountains to combat the catastrophic floods that occurred between the 1880s and the First World War. Among others, it documents dams, nurseries, planting works, canals, torrents, avalanche paths and landslides.

Photographic campaigns were carried out on these same sites at regular intervals. This historical approach was invested with scientific objectivity, because at the time, photography played the role of witness, or even of proof. It served as a form of "propaganda" intended to legitimise this strategy, which was launched on a large scale (18 departments involved) in all the mountainous areas of France, and which also had a long-term perspective.

The photographs are supplemented by other documents such as drawings, sketches, plans and sections. They are all captioned and documented according to a precise protocol, which gives this exceptional collection a unique scientific and technical value.

    Dykes, groynes, dredging and channels also work in the mountains

    The civil engineering works described here often, but not exclusively, concern the alluvial cone, i.e. the hill formed by the deposits of the torrent as it flows into the valley. This is often where homes and infrastructure are located. These structures provide direct and immediate protection for people and their property and complement the work carried out in the reception basin.

    Natural Risks

    Live brush check dams, grass seeding and reforestation, indirect protection

    Since the 1860s, government departments have been working to secure natural and human habitats threatened by erosion and mountain torrents. Civil engineering and environemental engineering techniques are used to stabilise banks and reduce the slope of torrents.
