Palácio Itamaraty, Brazil's Ministry of Foreign Affairs in Brasília, is a renowned architectural masterpiece by Oscar Niemeyer and a significant tourist attraction. Visits are primarily conducted via free, mandatory guided tours offered on weekdays, typically lasting 60-90 minutes, and booking in advance is highly recommended, especially for groups, as the palace may be closed for official events or on weekends/holidays. While the exterior and main areas are generally accessible, visitors with mobility concerns should inquire directly about specific elevator access to all levels. Solo exploration of the interior is not permitted, but the exterior gardens are usually viewable independently. The cost for entry and tours is typically free, making it an excellent cultural experience. Visitors should plan their trip during operating hours, usually between 10:00 AM and 5:00 PM on weekdays, and verify current schedules before visiting.
