Between 1915 and 1917 heavy fights took place in the high Alpine areas of the Dolomites between Italian and Austrian-German forces.

Many of the military installations of that time are still visible today, fortifications, loopholes in rocks, rusty remnants of grenades.

The idea to preserve the old military trails and installations as part of a reconciliation project between Tyrol and Italy started soon after the Gruber–De Gasperi Agreement (1946).

The agreement intended to lead to more autonomy for South Tyrol, which had been separated from Austria in 1919.

Today the trail is a popular destination for hikers, mountain-bikers and other tourists.
