The Fort of Infernet, located in the Susa Valley, is one of the fortifications of the region, built between the 19th and early 20th centuries as part of the Italian defensive system against potential French threats. This fort is located at about 2,800 meters above sea level and is strategically positioned to control the surrounding valleys. The Infernet was designed primarily as a high-altitude battery, with a robust structure capable of housing cannons and a limited crew. Its dominant position offered a strategic view of the valley and important control over the connections between Italy and France. Today the site can be visited, although in not perfectly preserved conditions, and is an interesting destination for hikers and military history enthusiasts

Tallest military fort in Europe. The climb is long and tiring and very crowded in the months of July-August but once at the top every effort is rewarded
