There is hardly anything left of Stetteneck Castle, and its position near Saint Jacob's church near Pincan could only be confirmed in 2000 thanks to archaeological excavations. Yet the castle played an important role in the development of the village and new supplies were brought mainly to San Giacomo to provide for its inhabitants. The Stetteneck family was wiped out at the start of the 14th century for political reasons.

Wolkenstein Castle, today a ruin, was a fortress set in Stevia rock face at the start of Langental valley (then Ciastel de Val). There used to be two castles standing here to safeguard Trai Paian long-distance path. Today's castle was built around 1200 and later taken over by Meinhard II, who elevated it to a court seat and equipped it with supplies. After 1370, the castle passed into the hands of the Wolkenstein family.
