Forte Tre Sassi Museum, Military history museum in Passo Valparola, Cortina d'Ampezzo, Italy.
Forte Tre Sassi Museum is a former fortress in the Dolomites housing artifacts from the First World War. The collection includes weapons, uniforms, photographs, and objects left behind by soldiers stationed here during the conflict.
The fortress was built in 1897 as an artillery post for the Austro-Hungarian Empire. Later it was reinforced to strengthen its defenses against the growing military threats of the period.
The name "Tre Sassi" comes from three large rock formations visible on the site. Walking through, you notice how the exhibits focus on the soldiers' daily routines and struggles living at such high altitude.
The museum sits at high elevation and requires decent physical fitness for the approach. Warm clothing is essential, as temperatures remain low throughout the year.
From the fort you can see five mountain passes at once, making it a strategic vantage point. This view reveals how well defenders could control the surrounding area.
