In this area are the remains of defensive works that the Austro-Hungarians planned and began to build but which they were unable to complete due to the precautionary retreat of the lines at the beginning of the conflict.
Mount Vignola should in fact have housed a fort of the fortified belt of Vallagarina which from Baldo should have reached as far as Pasubio.
In fact, the Austro-Hungarian Empire was unable to carry out these projects and in 1915 the lines were pulled back, allowing a rapid Italian advance.
Once you reach the top of this mountain you will understand why it was chosen by the imperial genius as the seat of a fort. The gaze ranges from Pasubio to the Small Dolomites, the Lessini and even to Garda, the Adamello, the Presanella, the Brenta. But even more interesting is to see how the entire course of Vallagarina and Adige can be observed from north to south.
Also note the great impluvium for the collection of rainwater from the barracks still in perfect condition, built by the Austro-Hungarians. In the vicinity there are also the ruins of the barracks dismantled by the locals to rebuild their homes at the end of the war.
On the top of Monte Vignola there are some circular concrete posts for the anti-aircraft artillery built by the Italian troops after 1915.
Continuing on you can see 2 suggestive tunnels dug into the rock by the Italian military engineers, crossing scraps of drilling material and bases for the cableway that went up from the valley floor as well as the ruins of Italian barracks and artillery posts.
