Plaza de Mayo
Every defining moment in Argentine political life — from the May Revolution to the country's largest street protests — has played out on this one square.

Formed in 1884 when a colonnade dividing two older colonial plazas was demolished, Plaza de Mayo puts the Casa Rosada, the Cabildo, and the Metropolitan Cathedral within a single sightline. Its roots go back to 1580 and Juan de Garay's founding of Buenos Aires itself, making the ground underfoot as layered as any square in South America.
What to look for
- Pirámide de Mayo at the center — inaugurated in 1811 on the first anniversary of the May Revolution, it became Buenos Aires' first national monument
- Casa Rosada on the square's edge — not a museum replica but the active seat of the President of Argentina
- The Cabildo — one of several significant monuments and points of interest surrounding Plaza de Mayo
Three subway lines stop directly below: Line A (Plaza de Mayo), Line D (Catedral), and Line E (Bolívar).
