It is located on the summit of Monte Grappa between the provinces of Treviso and Vicenza, at 1,776 meters above sea level. Access to the memorial is via the Strada Cadorna, built by the army on the orders of General Luigi Cadorna to bring construction materials for the fortification on Monte Grappa in 1917.
