Brasília is the federal capital of Brazil. 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 are estimated to be Brazil's 4th most populous city. Brasília has a tropical savanna climate with two distinct seasons: the rainy season, from October to April, and a dry season, from May to September.  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 was also chosen as a UNESCO World Heritage Site due to its modernist architecture and uniquely artistic urban planning.
