The Lagazuoi Open-Air Museum

Mount Lagazuoi is a veritable "rock castle" with pinnacles, rock towers and military bases inside the mountain.

During the Great War, the Italian and Austro–Hungarian troops dug shelters for soldiers and weapons into the rock faces, transforming this mountain into an impenetrable 20th-century fortress.

Today, you can visit the restored tunnels, trenches, emplacements and machine gun posts in the Lagazuoi Open-Air Museum.
Numerous routes will take you on a behind-the-scenes tour of a dramatic war fought at a high altitude that was unique in the history of man.

As of this summer, the visit is made even more engaging thanks to our new app that allows you, by means of QR-codes on the panels placed along the routes, to download texts, images and audio recordings that offer an insight into lesser known aspects of the First World War.

The app is free of charge. You can download it here or by scanning one of the QR codes on the museum panels.
It remains available offline, even in the tunnels, where there is no network signal.

The War on Mt. Lagazuoi

A video with graphic simulation that illustrates the Great War on Mt. Lagazuoi, the occupation of the mountain and the digging out of the tunnels.

The entire museum area is crossed by paths viable on foot. Almost all the tunnels and trenches have been cleared and restored thanks to the work of numerous volunteers. Restoration of the steps has granted easier access to the sloping stretches of the tunnels.

There are various visiting routes, some longer and more difficult, others shorter and easier.

There are four ways to reach the summit of Mount Lagazuoi,
the heart of the Open-Air Museum:

  • on the Frontline Trail, a wide and well marked hiking trail that runs along the WW1-frontline on Mount Lagazuoi. This easy hike is suitable for everyone


  • through the Lagazuoi Tunnel, excavated by Italian soldiers on the Martini Ledge to the fore-summit 'Anticima' of the Piccolo Lagazuoi as a mine tunnel, which exploded on 20th June 1917. This is the most daring tunnel system built during the First World War. It is almost one kilometre long and has been completely restored

  • on the Kaiserjäger Path, a challenging equipped path with some exposed sections but with well placed wire ropes. The Kaiserjäger Path was the communication way between the bottom of the valley and the high emplacements on Mount Lagazuoi, and was used for supplying food, munitions, and war equipment. The path has now been repaired and can be travelled for its entire length.
