The cannon post "Fuss Nabois" (or "At the foot of the Nabois") is a big cave dug in an erratic boulder in which two 90 mm firing weapons were installed. These were quite powerful weapons as their range was about six kilometres and their weight was more than a ton. Most likely they were moved here from one of the forts of the Val Canale once the conflict began.
One of the cannons was housed in the cave and today you can still see the concrete base with the semi-circular track that allowed the cannon to rotate. The other instead was positioned inside a fort in wood and cement, which today has been reconstructed. Walking inside the tunnel (you will need a torch) you can reach the stairs that used to lead to the open-air post.
