Salorno, the gorge where the German-speaking world ends
At Salorno, in the province of Bolzano in Italy's far north, the Adige valley squeezes between Monte Alto and the Favogna plateau. Through this gorge runs the language border between the German-speaking and Italian-speaking areas, a line that took shape around 1600, hardened in the nineteenth century and ignores every political frontier. On 5 September 1946, on the margins of the Paris Peace Conference, Alcide De Gasperi and Austria's foreign minister Karl Gruber signed the agreement granting South Tyroleans schooling in their mother tongue and official use of German. That sheet of paper became Annex IV of the 1947 peace treaty.
