Brasília is the federal capital of Brazil and seat of government of the Federal District. The city is located atop the Brazilian highlands in the country's center-western region. It was founded on April 21, 1960, to serve as the new national capital. Brasília and its metro area were estimated to be Brazil's 4th most populous city. Among major Latin American cities, Brasília has the highest GDP per capita at R$61,915.
Brasília was planned and developed by Lúcio Costa and Oscar Niemeyer in 1956 to move the capital from Rio de Janeiro to a more central location. The landscape architect was Roberto Burle Marx. The city's design divides it into numbered blocks as well as sectors for specified activities, such as the Hotel Sector, the Banking Sector and the Embassy Sector. Brasília was chosen as a UNESCO World Heritage Site due to its modernist architecture and uniquely artistic urban planning.
The centers of all three branches of the federal government of Brazil are in Brasília, including the Congress, President, and Supreme Court. The city also hosts 124 foreign embassies. Brasília International Airport connects the capital to all major Brazilian cities and many international destinations, and is the third busiest airport in Brazil. It is the second most populous Portuguese-speaking capital city after Luanda. The city was one of the main host cities of the 2014 FIFA World Cup and hosted some of the soccer matches during the 2016 Summer Olympic Games. Brasília also hosted the 2013 FIFA Confederations Cup.
The city has a unique status in Brazil, as it is an administrative division rather than a legal municipality like other cities in Brazil. Although Brasília is used as a synonym for the Federal District through synecdoche, the Federal District is composed of 31 administrative regions, only one of which is the area of the originally planned city, also called Plano Piloto. The rest of the Federal District is considered by IBGE to make up Brasília's metro area.
