Barn was built in the late eighteenth century. He was a farm owned by the castle. The cellar of the building is brick, while the top two floors granary is wooden. Inside there are two rooms for storing grain and a small hole in the front door for the cat, who guarded the grain. In 1996, the granary has been renovated, but since 1998 there you can see the exhibition "The Art of the People of Spis."
