Praça dos Três Poderes, Brasília, Brazil

Praça dos Três Poderes (Portuguese for Square of the Three Powers) is a plaza in Brasília, thecapital 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 (presidential office); the Legislativerepresented by the Congresso Nacional (National Congress); and the Judiciary, represented by theSupremo Tribunal Federal (Federal Supreme Court).

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 (in this case, continuously). The Brazilian flag hoisted weights about 600 kilograms (1300 pounds) and has 7,000 square metres(70×100 m = 230×330 feet)^{[citation needed]} and has never been taken down (without a simultaneous replacement) 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 thePresident of Brazil.
