Architecture Moderne du XX siècle de la Ville de M by Stanislaw Warwas
Montevideo is known for its Ciudad Vieja (Old City) which is mostly in Art Deco style with Palacio Selvo as the most iconic building. When I visited Uruguay Palacio Selvo was not open to visitors. It had antennas hanging over its top which made any attempt to take a decent photo of the monument fail. On postcards some photo shop was discretely applied to remove it. Now I read they are planning to dismantle the antenna.
The Ciudad Vieja is not spectacular and despite the fact it is the only such example of Art Deco I visited I guess there are other better examples available.
