Val-Cenis - Lanslebourg-Mont-Cenis

Built in 1861by the young kingdom of Italy that equipped Mont Cenis with several forts, 1/2 hour on foot.


Since 1861, the priorities of the Kingdom of Italy have been unity and the defence of the territory. Thus, he equipped the site of Mont-Cenis with several forts, including that of Ronce. Built at an altitude of 2286 m, it offers a very beautiful panorama of the Mont-Cenis lake.
At the end of the 19th century, the young Italy wanted to ensure the control of Mont-Cenis, a millenary transalpine axis. It was in a context of diplomatic tensions with France that Italy fortified Mont-Cenis by equipping it with several forts. The fort of Ronce, which dominates the whole pass, was built from 1877 to 1880 on a circular plan with two levels of fire, adapted to the new possibilities of rifled artillery.
