Trieste too for centuries if i recall correctly, also Milan and Venice spent some time under Habsburgs, so yeah old Habsburg Monarchy really connected vast areas of Central, Eastern and Mediterranean parts of Europe (Empire spread on territory of what is now modern Ukraine all they way to Italy, from north where it controlled parts of Poland with Krakow all the way to what is now Albania on Adriatic, it was huge and incredibly ethnically diverse country). Of course with modern times things change, people all around the world are all now much more linked, but i guess these kind of old links still got some importance in people mindsIndeed, and of course Italy has a land border with Slovenia, and is just across the water from Croatia. Bound to be a connection, especially as, as you say, the Sudi Tirol area of Italy was part of the same Austro-Hungarian empire for a long time.
