Argentina has no "freedom of panorama" provision in its copyright law, neither are buildings mentioned among works to which copyright apply. 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.”
