The Trenchers of Monte Campolongo - not to be confused with the mountain of the same name and its fort exactly on the opposite western side of the Asiago Plateau - are a long and deep Italian trench from the First World War, dug on a promontory which dominates the final stretch of the Val Brenta. It had no active role during the Great War, but served as an extreme bulwark to prevent a possible invasion of the Austro-Hungarian army from Valsugana. Cleaned and recovered, it features walkways, outposts, tunnels and shelters in a dense and silent forest: today the vegetation largely covers the view, especially in summer, but at the time the view of the valley was clean. You can follow the winding of the trench from inside or from above, along a path complete with little bridges... or a little and a little!

Cave with a considerable development of over 400 meters. At the entrance it immediately divides into two narrow and winding branches: the Ramo dei Ghiri, on the right, and the Ramo dee Strighe, on the left. The tunnels are twisted, very narrow (so much so that the backpack is an impediment to leave at the entrance!), in total darkness, with protruding concretions and narrow passages that at a certain point force you to advance on all fours or to crawl. Entering it is quite impressive: avoid if you are afraid of closed and narrow spaces, complete darkness, bats, cave crickets, spiders (present in the initial meters) and various creatures of the darkness! According to legend, the anguane live near a water source or a stream, inside caves or grottos: hence the toponym 'buso' = hole in Venetian dialect, to be understood as a home or refuge. https://www.ecovicentino.it/esplorare-il-vicentino/la-valle-delle-anguane-e-la-carega-del-diavolo-a-laverda/

Two small and close together Italian shelters from the Great War, dug into the rock: part of the rear defensive line of the mountain range, as an extreme barrier on the southern edge of the Asiago Plateau against a possible Austro-Hungarian invasion attempt in the Po Valley.

Italian gallery of the Great War: part of the rear defensive line of the mountain belt, as an extreme barrier of the southern edge of the Asiago plateau against a possible Austro-Hungarian invasion attempt in the Po Valley. Narrow, straight, 60 meters long, with 3 exits: total darkness / front light. In the middle of Sojo Park, with a scary art installation inside!

Here the path goes through a small tunnel in the mountain, from which a passage branches off. We didn't dare to explore it without a flashlight :)
