Until the end of World War I the border between Austria-Hungary and Italy ran over Marmolada, so it formed part of the front line during that conflict. Austro-Hungarian soldiers were quartered in deep tunnels bored into the northern face's glacier, and Italian soldiers were quartered on the south face's rocky precipices. It was also the site of fierce mine warfare on the Italian Front. As glaciers retreat, soldiers' remains and belongings are occasionally discovered.
