Near the Generator Cave you can visit Mt. Ermada Cave, the most famous amongst those included in the Museum. Discovered only in 1969, this cave used to accommodate the Austro-Hungarian troops who fought on the frontline.
You can access it both through its natural and artificial entrance, the latter excavated to facilitate the passage of soldiers.
The natural entrance leads to a slide of soil and stone concealing the terraced flooring built by the military to accommodate the troops. At its end, a central cavity opens up, which can be reached also from the artificial entrance; it is about a hundred metres long but in better conditions than the natural entrance.
The central cavity hosts several remains of the Great War. On the walls, you can still see the metal brackets with insulators made of porcelain, an unmistakable sign of the presence of electricity, while several calcareous concretions have been ruined by the fumes of the generators that were deployed to make the cave a liveable place. Continuing the descent into the cave, a concrete staircase on the right can be climbed (with caution) to reach a plan, where you can see some petrified jute bags.
