Palacio Salvo, at the intersection of 18 de Julio Avenue and Plaza Independencia, was designed by the architect Mario Palanti and completed in 1925. Palanti, an Italian immigrant living in Buenos Aires, used a similar design for his Palacio Barolo in Buenos Aires, Argentina. Palacio Salvo stands 100 metres (330 ft) high, including its antenna. It is built on the former site of the Confiteria La Giralda, renowned for being where Gerardo Matos Rodriguez wrote his tango "La Cumparsita" (1917.) Palacio Salvo was originally intended to function as a hotel but is now a mixture of offices and private residences.

Fluidity of racial categories aside, the "biologification" of race in Brazil referred above would match contemporary concepts of race in the United States quite closely, though, if Brazilians are supposed to choose their race as one among, Asian and Indigenous apart, three IBGE's census categories. While assimilated Amerindians and people with very high quantities of Amerindian ancestry are usually grouped as caboclos, a subgroup of pardos which roughly translates as both mestizo and hillbilly, for those of lower quantity of Amerindian descent a higher European genetic contribution is expected to be grouped as a pardo. In several genetic tests, people with less than 60-65% of European descent and 5-10% of Amerindian descent usually cluster with Afro-Brazilians (as reported by the individuals), or 6.9% of the population, and those with about 45% or more of Subsaharan contribution most times do so (in average, Afro-Brazilian DNA was reported to be about 50% Subsaharan African, 37% European and 13% Amerindian).
What do people with less than 60-65% of European descent usually cluster with?
Afro-Brazilians

There is a wide consensus that the racial categories that are common in everyday usage are socially constructed, and that racial groups cannot be biologically defined. Nonetheless, some scholars argue that racial categories obviously correlate with biological traits (e.g. phenotype) to some degree, and that certain genetic markers have varying frequencies among human populations, some of which correspond more or less to traditional racial groupings. For this reason, there is no current consensus about whether racial categories can be considered to have significance for understanding human genetic variation.
Some genetic markers have varying frequencies among what populations?
