The last metres of the spectacular military road of the 52 Gallerie, in the memorial zone of the Pasubio.
Most mountain paths are recent tracks, first opened by shepherds and valley inhabitants, then consolidated by the Alpine Clubs and local authorities. But some paths have more complex or ancient histories, from old mule tracks to military roads, bearing witness to the different roles these routes have played over the centuries. They were often used for strategic purposes, such as reaching alpine villages and defence in wartime, or to make trade (or smuggling) and communication between valleys easier.
Some of the routes in this section have ancient histories, such as the Via Mala cut into the Cardinello gorge, which saw Napoleonic troops pass through. Many routes have a military background, often linked to the First World War, such as the Linea Cadorna, a system of fortifications and trenches built between 1916 and 1918 along the border between Italy and Switzerland, or the spectacular Strada delle 52 Gallerie. On these paths we can see up close the traces left by the troops and reflect on the hardships and challenges soldiers faced in such harsh surroundings.
Walking the historic trails of the Alps is especially fascinating because it lets you immerse yourself in a kind of open-air museum. Along these routes, hikers can discover remarkable works of engineering, such as bridges, tunnels and terraces, that bear witness to the skill and tenacity of the people who built and travelled these routes over the centuries.
Good to know about historic trails
The Strada delle 52 Gallerie was built over a few months of 1917 by the 33rd Miners Company of the engineers, led by Lieutenant Giuseppe Zappa, to supply the Pasubio front line out of reach of enemy fire; of its roughly six and a half kilometres, more than two run through tunnels. In the same year, on the Lagazuoi, Italian and Austro-Hungarian troops fought a war of mines, digging tunnels beneath each other's positions and detonating charges that changed the very shape of the mountain. Those tunnels are now part of an open-air museum with free entry, but they remain dark, damp and narrow, so a head torch is essential and a helmet is a good idea.
Not every historic trail is military. In Valle Gesso the mule tracks and former military roads date partly from the time when Victor Emmanuel II, having secured exclusive hunting rights in 1857, had the royal hunting lodge of the Valasco built, now a mountain hut; the Tracciolino was opened in the 1930s as a service track for the dams of Val dei Ratti and Val Codera, with a small railway. As for the remains of the Great War, Italian Law 78 of 2001 recognises their historical value and governs their protection: the practical rule is to take nothing away and to report anything that looks significant.
