"The dyke must be made and will be made… and what will happen to people, their properties, belongings, houses, lives?” Bois Sylvaine (extract from an interview with a 92-year old man who used to live in Fornet, Valgrisenche, Aosta). In 1959, the villages of Sevey, Suplun, Beauregard, Chappuis and Fornet were flooded by the water overflowing the basin of Beauregard dyke, which was built regardless of landslide hazard and the instability of the surrounding mountains. People had to leave their land, houses, valley lives and their roots. Some found a new home in France, others in a less distant valley. In 1962, soon after the Vajont tragedy, the water level of the dyke was reduced for security reasons from 80 million cubic metres of water to 5 million and as a consequence the ruins of the village of Fornet emerged. The villages were never repopulated, but every year some people return to their homeland valley answering the ancestral call of the mountains.
