The Austrian–Italian border is a 404 km (251 mi) land border along the Alps between the Republic of Italy and the Republic of Austria. Although a border between Austria and Italy has existed since the 1861 Proclamation of the Kingdom of Italy, most of the current modern-day border was only established in 1920, after the First World War. It has been an EU internal border since 1 January 1995. The border was last changed in 1947.
