The Plaza de Mayo, located in the Autonomous City of Buenos Aires, is in front of the Casa Rosada, seat of the National Executive Power. Created in 1884 after the demolition of the Recova Vieja, it joins the old Victoria and Fuerte squares. The square is located in the neighborhood of Montserrat, surrounded by Hipólito Yrigoyen, Balcarce, Avenida Rivadavia and Bolívar Streets, with important avenues such as Presidente Julio A. Roca, Presidente Roque Sáenz Peña and Avenida de Mayo starting from its west side. In its surroundings are monuments such as the historic Cabildo, the Metropolitan Cathedral and the Casa Rosada.

Below the square, of approximately two hectares, are the subway stations Plaza de Mayo (line A), Catedral (line D) and Bolívar (line E), in addition to numerous bus lines that facilitate transportation in the city.

Plaza de Mayo has been the scene of important popular demonstrations and historical events in Argentina, from the May Revolution of 1810 to the current demonstrations. On May 25, 1941, a bronze commemorative plaque was installed in the square by the National Commission of Museums and Historical Monuments, the work of sculptor Manuel Félix Vilaboa, which summarizes its history highlighting key moments such as the founding of Buenos Aires by Juan de Garay in 1580, the Declaration of Independence and the May Revolution.

The square has had several names throughout its history, reflecting its evolution and the changes in its surroundings and function. The Recova, a construction that divided the square, was finally demolished in 1884, unifying the space. The Pirámide de Mayo, erected in 1811 to commemorate the May Revolution, has been a central and symbolic monument of the plaza.

Throughout the 19th and 20th centuries, the plaza underwent several remodeling and modifications, such as the installation of the equestrian statue of Manuel Belgrano in 1873 and the fountains that were later moved. In the 20th century, the square was modernized with the installation of ponds, electric lighting and the incorporation of the Plaza de Mayo subway station.

In 2005, the square was declared a Historic Site by the Legislature of Buenos Aires, and white handkerchiefs, symbol of the Mothers of Plaza de Mayo, were painted around it in memory of those who disappeared during the military dictatorship.

This historic square continues to be a crucial meeting point for the political and social life of Buenos Aires and Argentina.
