See Brasília’s official state buildings and one of the world’s largest national flags at this impressive plaza, home to three branches of government.

The Square of the Three Powers (Praça dos Três Poderes) is the political power base of the country. The spacious square is home to buildings representing the three branches of government, each one a fascinating example of modern Brazilian architecture designed by Oscar Niemeyer. The plaza also has the world’s largest flag to be continuously flown. Enjoy a stroll round the square and tour its landmark structures.

See the Palácio do Planalto, which represents the executive branch of government. Marvel at the building’s futuristic design with its white curved columns and large ramp leading to the entrance. The palácio is open to the public on Sundays only. Take the opportunity to tour the palace’s four floors to see temporary art installations, majestic halls and the president’s office.

Admire the twin towers of the National Congress building, where the legislative branch is located. Observe the domes on either side of the towers, which house the Senate and the Chamber of Deputies.

The Supreme Federal Court building represents the judiciary. Appreciate the building’s innovative design, with curved columns that seem to suspend the structure off the ground. Outside is a white stone sculpture called Justice, a figure of Lady Justice wearing a blindfold and holding a scepter. Look for other monuments in the plaza, such as The Warriors sculpture and the Israel Pinheiro Monument.

Gaze up at the Brazilian flag flying above the square. It was first raised in 1960 to mark the city’s inception as the nation’s capital. The flag is changed monthly in a ceremony officiated by soldiers and occasionally the president of Brazil. 

The Praça dos Três Poderes is located on the eastern end of the Monumental Axis. Take a bus down the famous avenue to the plaza or ride the metro. Nearby attractions include the Cathedral of Brasília, Mané Garrincha Stadium and the JK Memorial.
