Val di Sole boasts a history that has been written over the course of millenniums. Some thousands of years before Christ the Celts settled here, followed by the Rhaetians and Romans. After that, the Franks passed through the area, then the prince-bishops of Trento and finally the Austro-Hungarians ruled. In the 19th century, Irredentistic movements arose; in World War I, Val di Sole was frontier land, and after World War II the emigration phenomenon accelerated. With so much history as a background, Val di Sole treasures rural buildings, strongholds, castles, palaces and churches, where sometimes you find real "hidden jewels".
