Plaza de Mayo used to be two squares. A colonnade divided them until the city pulled it down in 1884.

Since then it’s had a busy political life. Perón’s rallies sometimes drew hundreds of thousands, and in 1955 military rebels bombed the plaza and the presidential palace. The Mothers of Plaza de Mayo, whose children disappeared under the dictatorship, began marching here in 1977. A headscarf symbol is tiled into the pavement for them.

VoiceMap’s self-guided audio tours use the plaza to show how two British invasions pushed Buenos Aires towards revolution in 1810. They also tell the Mothers’ story through their founder, Azucena Villaflor.
