Discover all our routes on www.viaggiatorelento.com Following the fortification of Brestovec during the Great War, it was decided to also dig a gun tunnel. The excavation work for the gun tunnels, carried out by the 3rd Company of the 5th Mining Engineer Regiment, began in January 1917 and was completed the following August. The work was equipped with 8 positions for 149/A pieces, served by a long battery corridor overlooking numerous cavities and secondary tunnels (reserves, shelters for gunners, etc.). There is no news about the actual military use of the work: a couple of months after its completion, in fact, it was abandoned due to the collapse of the Isonzo front following the defeat of Caporetto. It is worth remembering the engraving found in a nearby trench "Let's fly to peace" which has now become the motto of the renovation of the entire tunnel. It should be noted, however, that it was partially reused by the Italian Army during the Cold War, when the entire Brestovec was refortified to control the border of the Iron Curtain which ran a short distance away.
