The civic buildings in Brasilia are stunning architectural statements, still futuristic in form, some of them even spaceship-like. Whether they succeed on a human scale is another matter and Brasilia has been criticised as being not easy to live in without a car but, nowadays, that stricture could equally be applied to cities and towns with more conventional architecture.
Images of Brasilia along with other designs by Niemeyer can be found here.
Oscar Niemeyer 15/12/1907 – 5/12/2012. So it goes.
