|Article 25a(4) of the Finnish copyright law permits panorama freedom for buildings, both exteriors and interiors, regardless of whether the place is public (laws of privacy do apply).
Freedom of panorama (article 25a(3)) does cover taking photos (or otherwise reproduce in pictorial form) of art in or in the immediate vicinity of a public place, but the reproductions may not be used commercially (and thus not uploaded to Commons), when the work of art is the central element of the picture. Pictures of works of art permanently located in public places can be used non-commercially or as illustrations to texts in newspapers and periodicals. Published works of art may according to article 25 also be used e.g. as illustrations to scientific texts or criticism.
