Serbian copyright law allows 2D reproductions of permanently publicly displayed works, i. e. the full Freedom of Panorama (translation of relevant Article 51):
Article 51:
It is permitted to make two-dimensional reproductions of works permanently located on streets, squares or other open places accessible to public, and to distribute such reproductions, without author's permission or paying author's fee.
In accordance with Article 41, "the name of that work's author and the source from which the work was taken shall be quoted."
