Brasilia is a World Heritage site, described by UNESCO as, "a landmark in the history of town planning." Brasilia was planned and developed in the 1950s by planner Lucio Costa, and the city's architect was Oscar Niemeyer.
The city's design emphasizes both the need for easy transportation and the necessity of transportation. In other words, the city is designed around the car, for the car. Uses are separated, making the city unwalkable. The city's modern architecture is uninviting and bland and sterile. Brazil's capitol is a futuristic concrete wasteland, a contradiction of it's own character and people. There may be no greater failure of modern city planning and of modern architecture.
