The Mitterberg Fortress, located on the hill of the same name near Sesto, dates back to 1884-89. Two years before construction began, the Triple Alliance between the Austro-Hungarian Empire and the Kingdom of Italy was signed. To strengthen this defensive alliance, numerous forts were built along the country's borders and passes, including the Mitterberg Fortress on the southern slope and the Haideck Fortress on the northern slope of Sesto. The goal of the 427,000-krona fortification was to seal off the Kreuzberg Saddle and, if necessary, block access to the Puster Valley. The forts were connected by telephone and visual telegraph.
