Museo all'aperto della Grande Guerra — Sass de Stria

Sass de Stria preserves trenches and rock galleries from the First World War near Passo Valparola. The open-air museum records an Austro-Hungarian mountain position between the Lagazuoi and Col di Lana sectors.

Why it matters

The mountain's position helped defend approaches towards Val Badia and the Pusteria valley. Its fortifications show how observation, supply and shelter shaped warfare on the Dolomite front. The surviving remains place military history within the terrain that determined it.

What to notice

Communication trenches, galleries and firing positions cut into the rock reveal the relationship between defensive works and the mountain's natural forms. Covered passages offered protection from enemy fire, while observation points commanded the surrounding approaches. Later restoration made these structures part of a landscape of remembrance.

Context and history

Italian attacks began in the summer of 1915, followed by further fighting in October. Second Lieutenant Mario Fusetti died during the action of 17–18 October; his patrol's story became closely associated with the mountain. The restored positions commemorate the experience of the opposing armies without separating the remains from their high-altitude setting.
