Walk on the Paths of World War I: Itineraries and Points of Interest in Val di Fassa. 

In August 1914, Val di Fassa, part of the Austro-Hungarian Empire, became the battleground for conflicts between the Austro-Hungarian Army and the Italian Royal Army. The enemy forces concentrated their troops, particularly on the Marmolada (the white war), Costabella (mountain warfare), and Cima Bocche (infantry warfare). Trenches carved into the rock or soil, remains of barracks, and war relics in museums serve as lasting evidence. 

War sites, like the historical rings in the San Pellegrino area, are visitable and consistently maintained by the historical association "Sul fronte dei Ricordi" (On the Front of Memories). Others, like the legendary "City of Ice," have been forever erased by the relentless force of nature. 

The "Paths of the Great War" map, available for a fee (50% discount for Val di Fassa Guest Card holders), can be obtained at all tourist offices in the valley.
