''Praça dos Três Poderes'' (Portuguese for ''Square of the Three Powers'') is a plaza in Brasilia. The name is derived from the encounter of the three federal branches around the plaza: the Executive, represented by the Palácio do Planalto (presidential office); the Legislative, represented by the National Congress (Congresso Nacional); and the Judiciary branch, represented by the Supreme Federal Court (Supremo Tribunal Federal). It is a tourist attraction in Brasilia, designed by Lúcio Costa and Oscar Niemeyer as a place where the three branches would meet harmoniously.
