The Alpine Wall (Vallo Alpino) was an Italian system of fortifications along the 1,851 km (1,150 mi) of Italy's northern frontier. Built in the years leading up to World War II at the direction of Italian dictator Benito Mussolini, the defensive line faced France, Switzerland, Austria, and Yugoslavia. It was defended by the "Guardia alla Frontiera" (GaF), Italian special troops.^[1]
