Lagazuoi Open-Air War Museum

On the 2,835-metre summit of Mount Lagazuoi, above the Falzarego Pass on the historic border of South Tyrol, lies one of the most dramatic First World War sites in the Alps, an open-air museum of restored tunnels, trenches, and positions from the brutal mountain front of 1915–1917. When Italy declared war on Austria-Hungary in 1915, the front line ran directly through these peaks, and Italian and Austro-Hungarian soldiers fought a grim 'White War' at altitudes above 2,700 metres, exposed to cold, avalanche, and artillery as much as to each other. On Lagazuoi the Italians drove a daring system of galleries, some three kilometres in total, up through the rock from the Cengia Martini ledge toward the fore-summit in an attempt to mine the Austrian positions above; the Austrians tunnelled in turn, and the mountain was repeatedly shaken by enormous mine explosions whose craters still scar the cliffs. In the 1990s a cross-border project cleared and restored the main tunnel and side galleries to their original extent, fitting them with fixed cables and walkways so that visitors can descend through the mountain itself, passing observation slits, magazines, and dormitories cut into the rock. The site forms part of a wider five-square-kilometre open-air museum that also includes the Italian batteries at Cinque Torri, the Austrian positions at Sasso di Stria, and the Tre Sassi fort museum at the Valparola Pass. Reached by cable car from the Falzarego Pass or on signed front-line trails, Lagazuoi is at once a place of remembrance and a spectacular Dolomite viewpoint.
