Praça dos Três Poderes

Praça dos Três Poderes is a plaza in Brasília, the capital of Brazil. The name is derived from the presence of the three governmental powers around the plaza: the Executive, represented by the Palácio do Planalto; the Legislative represented by the Congresso Nacional; and the Judiciary, represented by the Supremo Tribunal Federal.

The plaza was designed by Lúcio Costa and Oscar Niemeyer as a place where the three powers would meet harmoniously, it has now become a tourist attraction of Brasília.
