BRASÍLIA — The Brazilian flag reads, “Ordem e Progresso” — “Order and Progress” — which is somewhat curious in this wonderfully jumbled and beautiful country. For an outsider who has visited the samba-infused nightclubs of Rio de Janeiro, the Amazonian jungle or São Paulo, with its ramshackle favelas and snarled traffic, order is not what springs to mind.

Until you arrive in Brasília.

In a country known for its flair for improvisation, Brasília stands in jarring contrast, a city so orderly, it is hard to believe it is really in Brazil.

“You can’t find samba, you can’t find a street corner for a beer, and you can’t find football,” said Henrik Brandão Jönsson, whose book “Fantasy Island: The Brave New Heart of Brazil” explores the history and culture of Brasília. “They don’t even have favelas in the central city. It is totally alien for Brazil.”
