Buenos Aires is Argentina’s big, cosmopolitan capital city. Its centre is the Plaza de Mayo, lined with stately 19th-century buildings including Casa Rosada, the iconic, balconied presidential palace. Other major attractions include Teatro Colón, a grand 1908 opera house with nearly 2,500 seats, and the modern MALBA museum, displaying Latin American art.

Population: 45% of Argentinians live in the capital city and the surrounding Province of Buenos Aires (‘Fighting on Fewer Fronts, The Economist, 8th August 2020, p.35).
