National Congress: Brasília's Iconic Legislative Landmark

At the National Congress in Brasília, you can take a free guided tour through the Senate and Chamber of Deputies, which runs about 50 minutes and covers the building's most important spaces. The tour starts from the Salão Negro (Black Hall) and includes the Green and Blue Halls, with entry every 30 minutes from 9 a.m. to 5 p.m. on Mondays, Fridays, weekends, and holidays. The building itself is a masterpiece by Oscar Niemeyer, completed in 1964, and its twin towers and contrasting domes are among the most photographed structures in Brazil.

Getting to the National Congress

The National Congress sits at the eastern end of the Monumental Axis, directly facing the Esplanada dos Ministérios. The address is Palácio do Congresso Nacional, Praça dos Três Poderes, Brasília – DF, 70160-900. Several bus lines stop nearby, including 152, 152.2, 152.3, 162, 161, 108, 108.3, and 108.5. Micro-buses known as zebrinhas also serve the area on routes 07, 08, 11, 16, 24, 25, 31, 32, and 113. If you prefer the metro, take the Orange or Green line to Central Station and walk about 1 kilometer west. Taxis can drop you at the Chapelaria (cloakroom) entrance of the Congress. For ride-hailing apps, set your destination to "Palácio do Congresso Nacional."

By bus or micro-bus

The DFTrans website (horarios.dftrans.df.gov.br) lists updated schedules for all lines. Buses can be crowded during rush hours, so allow extra time if you are visiting on a weekday morning.

By metro

The Central Station is a 15-minute walk from the Congress, but the stretch along the Monumental Axis is exposed and can be very hot around midday. Bring water and a hat.

By taxi or ride-hailing

Ask the driver to leave you at the Chapelaria, which is the designated drop-off point. From there, follow the signs to the visitor entrance.

Visiting the National Congress

Guided tours are free and open to the public. They run on Mondays, Fridays, weekends, and holidays from 9 a.m. to 5 p.m., with groups departing every 30 minutes. Tuesdays and Wednesdays are closed for visitation. Thursdays are reserved for scheduled school groups, though some spontaneous visits may be allowed with restrictions. The tour covers both the Senate and the Chamber of Deputies and lasts about 50 minutes. All visitors aged 12 and older must present a photo ID; foreigners should bring their passport. The tour may be canceled or have a reduced route without prior notice, especially on sitting days or during official events. Check the official website (www2.congressonacional.leg.br/visite) for the latest updates.

Opening hours and scheduling

Since September 2026, online booking is required for individual visitors to avoid queues. You can book through the official "Visite o Congresso Nacional" platform. Spontaneous visits may still be possible on less busy days, but booking guarantees your slot. Groups of more than 15 people, or those needing tours in English, Spanish, French, or Libras (Brazilian Sign Language), must schedule in advance.

Security and dress code

Weapons of any kind, including scissors and pliers, must be left in temporary custody with the legislative police. Eating is not allowed during the tour. On weekdays, a minimum dress standard applies — no shorts, flip-flops, or tank tops. This is a working government building, so dress respectfully. Weekends are more relaxed but still require covered shoulders and proper footwear.

What you will see

The route typically includes the Salão Negro (Black Hall), the Green Hall, the Blue Hall, and the plenary chambers of both houses. The Salão Negro is named for its dark marble walls and serves as the main reception area. The Green Hall is associated with the Chamber of Deputies, while the Blue Hall is linked to the Senate. You will also see the internal courtyards and the iconic exterior ramps. The tour does not enter the plenary floors when sessions are underway, but you can view them from the public gallery if available.

Architecture and highlights

Oscar Niemeyer designed the National Congress as a poetic expression of Brazil's new capital. The building consists of two 28-story twin towers connected by a bridge, forming an "H" shape — a reference to "homem" (man) and "humanism." In front of the towers are two dome structures: a convex dome that houses the Chamber of Deputies and a concave bowl-shaped dome that houses the Senate. The convex dome represents the people rising up, while the concave dome represents the Senate receiving the people's voice. The building was inaugurated on April 21, 1960, when the capital moved from Rio de Janeiro to Brasília.

The domes and towers

The twin towers are the tallest structures in the Praça dos Três Poderes and offer a striking contrast against the blue sky. The domes are inverted relative to each other — one faces up, the other down. This design is not only aesthetic but also functional: the convex dome allows for a wider view of the plenary hall, while the concave dome focuses light into the Senate chamber. Photographers should visit early morning or late afternoon when the light is softer and the shadows accentuate the curves.

The Salão Negro and Salão Branco

The Salão Negro is the main entrance and is often used for official receptions. Its dark marble walls and modern art collection set a formal tone. The Salão Branco, located in the basement, is used for smaller events and exhibitions. Both halls are included in the guided tour and offer a glimpse into the building's internal elegance.

Surrounding attractions

The National Congress is part of the Praça dos Três Poderes, which also includes the Palácio do Planalto (presidential office) and the Supremo Tribunal Federal (Supreme Court). A short walk along the Monumental Axis takes you to the Cathedral of Brasília, the National Museum, and the National Library. Plan at least half a day to explore this area. The entire set of buildings is a UNESCO World Heritage Site.

Best time to visit

Brasília has a dry season from May to September and a wet season from October to April. The dry months bring clear blue skies and comfortable temperatures (12–28°C), ideal for photographing the white modernist architecture. However, humidity can drop to 10–15% in August and September, so carry water and lip balm. The wet season has heavy afternoon storms, usually between 3 and 6 p.m., which can disrupt outdoor plans but also brings lush green landscapes and fewer tourists. Weekdays during the rainy season (except Tuesdays and Wednesdays when the Congress is closed) are the quietest. Avoid the July school holidays and national holiday weekends if you prefer smaller crowds.

Dry season (May–September)

This is the best time for sightseeing. The skies are cloudless, and the light is crisp. Mornings are pleasant, but by afternoon the sun can be intense. Visit the Congress early in the day to avoid the heat. The purple ipê trees bloom in June, adding color to the city.

Wet season (October–April)

Expect warm temperatures and frequent rain. Mornings are usually clear, so schedule outdoor activities before noon. Afternoon showers are often short but heavy. The advantage is fewer visitors and greener scenery. Bring a light rain jacket and waterproof shoes.

Avoiding crowds

Weekdays (Monday, Friday) are less crowded than weekends, but note that Tuesdays and Wednesdays are closed for visitation. If you visit on a weekend, arrive early — the first tour at 9 a.m. is usually the least crowded. Also check the legislative calendar; during peak sessions, some areas may be restricted.
