Le Chantier des Forts de l'Esseillon
Organised by Les Forts de l'Esseillon
18+ years Help restore the Forts de l'Esseillon! from June 30 to August 23, 2025
At the beginning of the 19th century, five original mountain forts were erected as a precaution against intrusion across the Alps. Our association is making them accessible, safe and in keeping with the original construction, and opening them to the general public.
