History
The Ortler Alps were part of the Italian front during World War I. In this area, the Austro-Hungarians and the Italians dug in during a trench war fought at altitudes above 3,000 m (10,000 ft) for most of the war. Some trenches are still visible today, and war relics continue to be found in the area.
