During the war, the mountain was the scene of intense mining warfare where over 30,000 kilograms of explosives were detonated in a single mine shaft.
The tunnels were originally constructed to protect troops from the harsh climate and direct artillery fire during the winter months.
The 'Lagazuoi Tunnel' is a complex network of man-made galleries that descends roughly 1,100 meters through the mountain interior.
The temperature inside the tunnel system remains consistently low, even during the peak of the summer season.
The museum site is part of the Great War circuit, connecting various historical locations throughout the Dolomites.
The Italian army occupied the summit of Piccolo Lagazuoi while the Austro-Hungarian forces held the nearby Tofana di Rozes.
Monte Lagazuoi Piccolo is home to an extensive open-air museum detailing the WWI Italian Front. Visitors can explore restored trenches, tunnels, and machine-gun posts carved directly into the Dolomite rock face by soldiers between 1915 and 1917. The site acts as a memorial to the 'War of Mines,' where opposing Austrian and Italian forces detonated explosives to collapse enemy positions. The tunnels are accessible to the public, though they require specific gear for safe navigation. The mountain peak provides an elevated vantage point overlooking the Falzarego Pass and the surrounding Fanes-Sennes-Braies Natural Park. The site is managed by the local tourism infrastructure which maintains the preserved battlements and historical markers. It remains one of the most significant sites for studying high-altitude alpine warfare in the 20th century.
The terrace at the top of the cable car station offers panoramic views of the Tofana group and the Marmolada glacier.
A high-powered headlamp is essential, as the tunnels are completely dark and require both hands for navigating ladders.
Sturdy, waterproof hiking boots are necessary due to the often wet and slippery conditions inside the mountain galleries.
Check local weather reports specifically for the mountain peak, as conditions can change rapidly compared to the valley floor.
Attempting the tunnels without proper lighting equipment or attempting to explore off-trail areas where historical ordnance may still be unstable.
The site is typically closed during the late autumn and spring months when the cable car is not in operation for seasonal maintenance.
Respect the site as a war memorial; refrain from removing any artifacts or disturbing the tunnel structures.
