The Palácio do Planalto (Portuguese pronunciation: [paˈlasju du plaˈnawtu]) in Brasília is the official workplace of the president of Brazil.

It is located at the Praça dos Três Poderes (Three Powers Plaza), to the east of the National Congress of Brazil and across from the Supreme Federal Court.

Oscar Niemeyer was chosen as the architect of the Palácio do Planalto and the building's construction, led by Construtora Rabello S.A., began on 10 July 1958.

The inauguration ceremony was attended by several foreign leaders and attracted thousands of spectators,[1] as it symbolised the transfer of the capital city from Rio de Janeiro to the center of the country.

Niemeyer's idea was to project an image of simplicity and modernity using fine lines and waves to compose the columns and exterior structures.

[1] The longitudinal lines of the palace are kept by a sequence of columns whose design is a variation of those at the Palácio da Alvorada, although they were arranged transversely to the body of the building.

The palace's façade is also composed by two strong elements: the ramp leading to the hall and the parlatorium (speaker's platform), from where the president and foreign heads of state can address the public at the Three Powers Plaza.

[8] A reflecting pool was built in 1991 to increase security around the palace and to balance humidity levels during the long dry season in Brasília.

The highlights in this hall are Haroldo Barroso's sculpture Evoluções and Djanira da Motta e Silva's painting Os Orixás.

The waiting rooms are decorated with furniture by Sergio Rodrigues and Oscar Niemeyer, and paintings by Emiliano Di Cavalcanti, Firmino Saldanha, Frans Krajcberg, Geraldo de Barros and Frank Schaeffer.

The bronze sculpture called O Flautista, by Bruno Giorgi, used to ornament the area but was destroyed during the invasion of Congress on 8 January 2023.

Highlights in the lounge include: a tapestry by Alberto Nicola; a draft of Tiradentes' bust, by Bruno Giorgi; and Cena Indígena, by Giovanni Oppido.
