Recently restored, it allows you to explore a long stretch of trench with a fascinating underground shelter. One of the historic sites of the Karst region worth exploring.

Suggestive location, recently renovated: the walkway is lit by floor lamps, from there there are various rooms with exhibitions and historical reconstructions. There is a staircase that leads outside where you can enjoy the view of the Vallone.

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.

During the excavation by Italian soldiers of the Joffre trench in Monfalcone, in the first moments of the Great War, an underground cave without any outlet was discovered. The fortuitous discovery allowed the Italian troops to gain shelter against enemy cannon fire and was named “Virgin” Cave. The cave has two entrances 12 meters apart and access is facilitated by stairways carved into the rock and above the main entrance there is a plaque with a female figure holding a palm branch in her hand.

Very simple path, suitable for everyone, which leads to an open-air museum dedicated to the First World War. Trenches, caves, tunnels and works of art make it easier to understand how life was lived on the front.
