The fort is at a 10-minute walk from the Télégraphe mountain pass. It overlooks the Maurienne Valley and offers greats views on the Arc valley.
It is open only in summer and with guides.


Built between 1885 and 1893, the fort du Télégraphe is located on the site of an old Chappe telegraphy relay station which linked Paris to Milan.
Its polygonal architecture (Séré de Rivières style) is well adapted to the spectacular geography of the area. The fort has also been used as a command post during the Italian offensive around Valloire and Valmeinier (Battle of the Alps - 10 to 25 June 1940)
