Brasilia

Brasília is the federal capital of Brazil and seat of government of the Federal District. The city is located at the top of the Brazilian highlands in the country's center-western region. It was founded by President Juscelino Kubitschek on April 21, 1960, to serve as the new national capital. Brasilia is estimated to be Brazil's third-most populous city. Among major Latin American cities, it has the highest GDP per capita.
Brasilia was a planned city developed by Lúcio Costa, Oscar Niemeyer and Joaquim Cardozo in 1956 in a scheme 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. Brasilia was inscribed as a UNESCO World Heritage Site in 1987 due to its modernist architecture and uniquely artistic urban planning. It was named "City of Design" by UNESCO in October 2017 and has been part of the Creative Cities Network since then.
All three branches of Brazil's federal government are centered in the city: executive, legislative and judiciary.
