Castel Roncolo is a medieval castle located a few kilometers from Bolzano. The castle is located on a rock spur in the Sarentino Valley. The Castle was built in 1237 by the will of the brothers Friedrich and Beral von Wangen. The Castle was abandoned and underwent a phase of decline. Only in the nineties and early 2000s the castle was restored and the original structure was re-established. Inside, the castle has the original layout and can still be visited today. Even today the medieval frescoes are in perfect condition with scenes regarding: ladies and knights, chivalrous scenes, ball games, hunting, fishing and dance scenes, naked men and animals, episodes from the stories of Tristan and Isolde. The frescoes of the castle are a rich testimony of the past, of the nobility, clothing and taste of the time. Certainly of great value is the so-called "Summer House", where inside there are the scenes of the legend of "Tristan and Isolde". The castle today hosts temporary exhibitions and medieval events related to court life and knightly culture.
