<P> A barnstar ( or barn star , primitive star , or Pennsylvania star ) is a painted object or image , often in the shape of a five - pointed star but occasionally in a circular `` wagon wheel '' style , used to decorate a barn in some parts of the United States , and many rural homes in Canada . They have no structural purpose but may be considered lucky , akin to a horseshoe mounted over a doorway . They are especially common in Pennsylvania and frequently seen in German - American farming communities . </P>
