The city planner Lúcio Costa laid out Brazilia like an abstract bird. Costa gave the palace of National Congress (Congresso Nacional) building pride of place at the head of his bird. The building’s architect Oscar Niemeyer, heavily influenced by Le Corbusier saw the building as a monument to Brazilian Modernism.
For the next 50+ years the Brazilian Senate have been buying up art to hang on the walls & recently made these archives public.
So a selection, a kind of “best of” what the art buyers at the Brazilian Senate see as befitting their highest Federal office and representative of the nation’s modernism.
