Comment: This is a copy of architect Lúcio Costa's urban design. As you can see in the center (look carefully), the core of the city is formed in the shape of a bow and arrow, airplane, or, as some describe it, a butterfly. On the other hand, Lúcio Costa was thinking of a cross.
For close-up view of the center of this design, see: => Brasília #4a.
