The region of Italy known as Trentino-Alto Adige or South Tyrol has an interesting history. It became part of Italy as a spoil of World War 1, and many of its residents have never been entirely comfortable with Italian control. It is a breathtakingly beautiful region, where German is heard more than Italian. The unique nature of this area has resulted in it being given a great deal of autonomy; Trentino-Alto Adige often does things its own way.
