Architecture is an indication of how a society wants to be seen. It has the ability to mask its age and sometimes its sources of reference. It is difficult for an uninformed walker to sense the time contained in the surrounding walls. Being cultural subjects or individuals modelled under the historical chronology of the West gives us a framework to vaguely classify architectural forms. But in a city of the New World, like Buenos Aires, these forms respond to the echo of multiple sources of inspiration, which implies a complex game in the correspondence between the specific historical forms and moments.
