This is the Registro Civil de la Ciudad de Buenos Aires. I know this because it is written above the entrance. I also know that it was built to commemorate something, presumably the establishment of the Registro Civil, between 1886 & 1943 because these two years are written elsewhere on the façade. More I can't really tell you other than the fact that there are three very nice Art Deco lamps hanging in the entrance.
