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.

Saint Jacob's church is assumed to be the oldest church in the valley and is thought to have been built by the lords of Stetteneck around 1200. It was first mentioned in records in 1246. The dedication of the church to Saint Jacob, guardian of travellers, is due to the fact that it lies on Troi Paian trade route. The church is equipped with local baroque sculptures, with the originals being stored in the museum.

This site is part of the tour "San Giacomo and its over-500-year-old farms".
