Argentina has no "freedom of panorama" provision in its copyright law. At least some think there is de facto freedom of panorama in Argentina regarding buildings:
It is uncontroversially accepted that buildings can be reproduced by paintings or photographs, without this reproduction infringing copyright.
Se ha admitido pacificamente que los edificios puedan ser reproducidos mediante pinturas o fotografías, sin estimarse que esta reproducción lesione los derechos de autor.
