Praça dos Três Poderes

Praça dos Três Poderes is the central civic plaza of Brasília, Federal District, Brazil, established with the inauguration of the city in 1960 as the symbolic center of the national government.

The site is notable for housing the three main branches of Brazil’s federal government within a single open space: the executive Palácio do Planalto, the legislative Congresso Nacional, and the judicial Supremo Tribunal Federal. The plaza also contains public monuments such as the Monumento aos Candangos, and is a focal point for official ceremonies and national celebrations.

The plaza and surrounding buildings were laid out as part of Brasília’s planned city project conceived by urban planner Lúcio Costa; many of the principal buildings were designed by architect Oscar Niemeyer and completed in the late 1950s and 1960, concurrent with the city’s inauguration.

Located on the Monumental Axis in the Plano Piloto sector of Brasília, the plaza forms the civic heart of the capital and is surrounded by government ministries and official residences.

• Ceremonial use: Official ceremonies and state events are commonly held on the plaza, with major national observances held on 21 April (Brasília's founding day).
• Best viewing points: The plaza sits at the heart of Brasília's Monumental Axis - the best viewpoints are from the opposite side of the axis or from the steps of the Congress for photographic compositions showing the three branches together.
