Considering a trip to the Dolomites and the Veneto this August, with visits to Venice (not again!), Padua, Verona, Castelrotto (Kastelruth), etc. Apparently the people in the Dolomites do not really think of themselves as Italian (they had been part of the Austro-Hungarian Empire until WW1, and Mussolini Italianized the names).
Found out there are many villages up there in the Dolomites where the people mostly speak Ladin (not to be confused with Ladino). Several million people in the Veneto speak Venetian, too. People in Castelrotto speak German.
Photos below of Castelrotto, which looks more alpine-German or Swiss than Italian. It's the south Tyrol:
