The Itamaraty Palace, also known as the Palace of the Arches, is the headquarters of the Ministry of Foreign Affairs of Brazil. It is located in the national capital of Brasília. The building was designed by architect Oscar Niemeyer and inaugurated on April 21, 1970. It is located to the east of the National Congress building along the Ministries Esplanade, near the Praça dos Três Poderes.
In Brazil, Itamaraty is generally used as a metonymy for the Ministry of Foreign Affairs. The name stems from that of the palace in Rio de Janeiro which was the headquarters of the ministry before the Brazilian capital and government were moved to Brasília.
