At the outbreak of the war, the area was heavily reinforced. The new defensive line descended from the Marzola, touching its lower peaks such as Dos dei Corvi, following the ridge to Mount Chegul. From there, the entrenched field extended to the Cimirlo Pass, guarded by the modern fortifications of Mount Celva, which also controlled the southern side of the Civezzano Barrier.
Mount Celva was transformed into a major stronghold, with many of its structures still visitable today.
Climbing toward the summit, one can see the “Path of the 100 Steps”, a long staircase built into the rock, and a large trench running across the lower part of Celva.
Below the summit, tunnels lead to two armored domes that once stood on the top.
From this sector too — particularly from Chegul and Celva — there are magnificent views of Trento, the surrounding mountains, and the Valsugana.
