About Brasília

Brasília is a city drawn with a ruler—cathedral, Congress, and the Esplanade unfold along a single monumental axis. May to September brings dry cerrado weather ideal for walking the ministries, sunset at the JK Bridge, and day trips to Chapada dos Veadeiros. Summer afternoons can bring heavy rain and intense heat; schedule outdoor architecture early. It rewards travelers who care about design, politics, and the audacity of building a capital from scratch in the 1960s.
