Passo dello Stelvio

Before the end of World War I, it formed the border between the Austro-Hungarian Empire and the Italian Kingdom. The Swiss had an outpost and a hotel (which was destroyed) on the Dreisprachenspitze (literally, Three-Language-Peak). During World War I, fierce battles were fought in the ice and snow of the area, with gun fire even crossing the Swiss area at times. The three nations made an agreement not to fire over Swiss territory, which jutted out in between Austria (to the north) and Italy (to the south). Instead they could fire down the pass, as Swiss territory was up and around the peak.[4][5] After 1919, with the expansion of Italy, the pass lost its strategic importance.
