7Brasilia, Brazil

In 1960, Brasilia was established as the capital of Brazil, and this marked the beginning of the city’s current urban planning.

The famous airplane-shaped design of the city was created by architect Lucio Costa, and it remains the only 20th-century city to be recognized as a UNESCO World Heritage site.
Despite criticisms of its highway system, Brasilia has become one of the most modern cities in the world.
