The Congresso Nacional is Brazil’s legislative seat at Praça dos Três Poderes in Brasília. Oscar Niemeyer’s design brings together two towers and two contrasting domes: the Senate occupies the concave form, while the Chamber of Deputies sits beneath the convex one. A guided visit can take you inside the deliberation chambers and halls, with context on Brazil’s constitution and political process. Look for the artworks and the Tunnel of Time, too. Tours are free, and English-language options are available, though less often than Portuguese tours.
The building and its two chambers
Oscar Niemeyer designed the Congresso Nacional as the home of Brazil’s two legislative houses: the Senate and the Chamber of Deputies. Its most recognizable features are the pair of tall towers and the contrasting domes. The Senate occupies the concave dome; the Chamber of Deputies is beneath the convex one. The towers hold offices and are linked by a tunnel.
The building forms part of Praça dos Três Poderes, alongside the Palácio do Planalto and the Supreme Federal Court. Together, these institutions represent Brazil’s executive, legislative and judicial branches. The Congress is also one of the defining works of Brasília’s modern architecture.
What to see inside
Free guided tours give visitors access to the chambers, halls and works of art, with explanations of Brazil’s constitution and legislative process. The Senate chamber is blue, while the Chamber of Deputies is green. The Tunnel of Time is another point of interest, along with an exhibit of Senate benches and microphones dating to 1867.
Artworks inside the complex include pieces by Athos Bulcão, Alfredo Ceschiatti, Di Cavalcanti, Marianne Peretti, Fayga Ostrower, Carybé and Maria Bonomi. Some works refer to significant events in Brazil’s recent history. Tour schedules include language options, but English tours may be less frequent than Portuguese ones.
