The Palais des Nations, built in the 1930s, serves as the European headquarters of the United Nations. Originally the headquarters for the League of Nations, this grand example of 20th-century architecture hosts important international conferences and diplomatic meetings. Visitors can tour the Assembly Hall, Council Chamber, and view artwork from member states.
Cool fact: The Assembly Hall is one of the largest conference rooms in the world, seating over 2,000 delegates, and is adorned with murals by Catalan artist José Maria Sert, symbolizing peace, progress, and justice.
