The largest and best preserved of the five forts of the Nava entrenched camp, built between 1880 and 1888 right on the summit of the pass. Today it can be visited and houses the Pro Loco tourist information office, a small geological museum and, in summer, exhibitions and events in its vaulted halls.
Built between 1880 and 1888 to bar the French route towards Piedmont, the entrenched camp of Nava is an imposing Savoy defensive system made of five forts: Centrale, Richermo, Pozzanghi, Bellarasco and Montescio. It has been a protected national heritage site since 1994.
