The military memorial, which is the only ossuary of fallen Italian soldiers in Slovenia, opened in 1938 by Benito Mussolini.

The third defence line of the Italian army during the First World War was on the Kolovrat Ridge (1,115 m), which offers incredible views and connects the Italian Veneto Region with the Soča Valley. The lookout spots, the firing trenches, the artillery positions for machine guns and the caverns are particularly interesting due to various details, such as the spiral staircase in one of the caverns and partly due to the original use of materials in the wartime. Fans of the alpine scenery will be able to get fantastic views from here. They open up over the former battlefield of the Isonzo Front, all the way from the Kanin and Krn Mountain Range to the Friuli Lowland and the Adriatic Sea.

The church celebrates the fallen Austro-Hungarian defenders of the Isonzo Front battlefield (1915–1917). As the most beautiful World War I memorial in the area of the Republic of Slovenia, it was placed on the list of particularly important European historical and cultural heritage back in 2007 and received European Heritage label in 2018.
