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.
The plaza is home to the largest flag in the world to be flown regularly. The Brazilian flag hoisted weighs about 600 kilograms and has never been taken down since the capital was inaugurated on 21 April 1960. The flag is changed monthly in the presence of Presidential Guard Battalion, Independence Dragoons, other troops and sometimes the President of Brazil.
