In the heart of Buenos Aires, Plaza de Mayo witnessed the spark of revolution on May
Plaza de Mayo: Cradle of a nation in search of its true legacy
« Freedom is not a gift, but a conquest. And every conquest has its price, its secret. »— Manuel Belgrano (popular attribution)
Plaza de Mayo, in the heart of Buenos Aires, is Argentina's quintessential historical site. It was here, in front of the Cabildo, that on May 25, 1810, the May Revolution erupted, marking the beginning of the independence process from Spain. Emblematic figures such as Mariano Moreno, Manuel Belgrano, and Cornelio Saavedra played crucial roles, laying the foundations of a new nation.
Over the centuries, Plaza de Mayo has been the stage for all major political and social events in the country, from patriotic celebrations to popular demonstrations. The Casa Rosada, seat of the presidency, and the Metropolitan Cathedral, which houses the mausoleum of General San Martín, frame this history-laden square, a silent witness to the hopes, struggles, and secrets that have forged Argentine identity.
