The Supreme Federal Court Palace is the seat of the Supreme Federal Court, Brazilian highest appealing court and constitutional court. It was designed by architect Oscar Niemeyer and the structural project was carried out by engineer Joaquim Cardozo.

Praça dos Três Poderes
Includes the seats of the country's 3 highest authorities: the Congress, the Presidential Palace (called Palácio do Planalto) and the Supreme Court. The axis itself is aligned such that on April 21 (Tiradentes Day, marking the death of the Brazilian independence martyr), the sun rises precisely between the two towers of Congress. The bronze statue of two abstract figures is named Os Candangos and represents the pioneering spirit of the workers who built the city. There's also a "blind justice" statue by the Supreme Court, a small museum about Juscelino Kubitschek, the Pantheon, the Eternal Flame monument, and a model, built to scale, of Brasilia itself, in an underground space.
Daily, Brazilian National Congress offers a guided visit. It starts every half hour from 09:00, in Salão Negro (access the main ramp). It lasts for 50 minutes. You cannot enter wearing shorts and slippers from Monday to Friday.
It houses the Ministry of Foreign Affairs, and stands out among the ministry buildings at Esplanada dos Ministérios for its beautiful architecture and sculptures.
With its 16 curved 90-ton concrete pillars and stained-glass panels, it is one of the world's most amazing modernist buildings.
Brasilia's newest museum was built to be the city's home for renowned national and international exhibitions. As of 2012, the outside space has become a regular venue to free concerts and events, and very popular for skating, but its collections are temporary and severely lacking both in size and importance. However, give it a try, it's free.
