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.

The photographical reproduction of this work is covered under the article 48 of the Brazil copyright law, which states: Works permanently located in public places may be freely represented by painting, drawing, photography and audiovisual processes.

Warning: FoP is allowed in Brazil, including commercial use, to some extent. Artworks placed in locations with access to the public can be freely represented by photography, painting, drawing and audiovisual means. Commercial use is allowed, as long as the artist's work is properly attributed, the representation does not consist in a reproduction. The existing jurisprudence consistently allows commercial use of artworks under FoP, as long as the artwork is accessory, and not detached from its surrounding elements, and therefore not unfairly used to produce revenue that by law belongs to the artist. Violation of those rights is frequently punished by Brazilian courts with pecuniary indemnisations to the offended party.
