The history of Upper Venosta Valley gives an insight into the conflicts between the Habsburg rulers and the people of Grisons. Thus, today we can admire impressive historic monuments, over 40 castles and palaces. Some are in ruins and only the vestiges of buildings remain, many however, were preserved from decay.

Of the best-preserved castles in South Tyrol is Churburg Castle above Sluderno/Schluderns. Erected in the 13th century, the medieval buildings were later converted into a Renaissance residence. One can see frescoes, chambers and chapels, as well as Europe's largest armour collection. It is also worth visiting the Lichtenberg ruin and Rotund Castle in Tubre/Taufers, as well as Fürstenburg Castle and the Fröhlich tower, as one of the five towers in Malles/Mals.
