Brasilia was built out on the brazilian savannah in four year during the 60s, based upon a masterplan made by Lúcio Costa. Most of the important buildings are designed by the brazilian architect Oscar Niemeyer.
The lay out of the urban plan resembles an airplane, containing two main axes with the main governmental functions in what would be the "cockpit" of the plane. The pilot plan with its huge open spaces, buildings, streets and public squares was meant to be represent an ideal city of future, true to the ideals of modernistic city planning of that time.
Today Brasilia stands out as a well planned utopian future city from the past. Whatever the conclusion might be on the urban planning, the collection of buildings stands out as an impressive work of modern architecture.
