This building houses the Ministry of Foreign Affairs and is one of the greatest achievements of the famous architect Oscar Niemeyer. It has a wonderful architectural design where a long line of symmetrical arches stand above a reflecting pond, and there is an entire set in beautiful gardens designed by the famous Brazilian architect Roberto Burle Marx. The lavishly designed interior surrounds a semi-roofed courtyard with garden. The building is open to the public and is a great place to visit.
