After the Italian forces conquered Mt. Sabotin in August 1916, the defenders retreated to their new defensive positions built on the south-western slope of Mt. Sveta Gora. The front positions were connected with the rear with a long tunnel dug under the so-called Hill of St. Francis of Asissi. The tunnel gave shelter to the battalion commanders and it even had a water trough. The tunnel is still well preserved and accessible. You can enter it from the south-western side of the hill, from the main road to Mt. Sveta Gora, near the X station of the via crucis. You have to bear in mind that part of the tunnel rises and you will have to climb up, using a steel cable for aid, this is why a headlamp and good hiking shoes are essential. Moreover, the ceiling is quite low in some parts so we recommend wearing a protective helmet. Due to the slippery terrain, do not enter the cave from the opposite direction.
