The headquarters of Brazil's Ministry of Foreign Affairs, completed in 1970, sits east of the Three Powers Plaza in a shallow reflecting pool. Niemeyer's elegant arches march around all four sides, and a sculpture by Bruno Giorgi — Meteoro, five abstract figures in white marble — stands on a podium in the water.
Inside is a striking double-height ceremonial hall, original mid-century Brazilian furniture, and a roof garden by landscape architect Roberto Burle Marx. Free guided tours run on weekdays at scheduled times — bring ID, and dress conservatively (no shorts).
