Brasilia is the capital of Brazil, where the country's leaders make important decisions. It was built from scratch in just a few years and is famous for its wide, modern, spaceship-like buildings.
You can see the curvy white Cathedral with its tall spikes, watch planes at the giant central plaza, and spot buildings shaped like bowls and domes.
Brasilia's buildings look like art from the future, with swooping curves and shiny glass everywhere.
From above, the whole city is shaped like an airplane, planned carefully before a single house was built.
