The Russian Chapel is erected in memory of, and as a warning against, the senselessness of the world wars. Between 1916 and 1917 the Russians themselves built a neat little chapel of round timber and bark. It has two small towers in the familiar Russian shape. Around the little church and along the road are Russian graves.
Vršič had strategic importance during the First World War, since it enabled the Austrian army easier access to the Isonzo front. The supply of war material went on without interruption. Vršič also had to be passable in all the winter months. Enormous quantities of snow were thrown off the road by Russian prisoners of war under the supervision of Austrian soldiers. One day an enormous avalanche buried the Russian camp. More than three hundred prisoners and some ten guards met their death under the snow.
