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.
