  • Address: Plaza de Mayo
  • Admission: Free

Plaza de Mayo is Buenos Aires’ political heart, first mapped out in 1580. Today, the grassy, treed plaza attracts visitors with cameras and relaxing locals, and is also the venue for rallies and gatherings.

The center of the plaza features an obelisk called the Pirámide de Mayo, erected to commemorate independence from Spain.

Grand 19th century buildings line the plaza, but the colonial arches that once circled the plaza are long gone.

Nearby are the city council buildings known as the Cabildo, the Casa Rosada government buildings and fine bank buildings.

Practical Info

Plaza de Mayo is in the heart of Buenos Aires, at the end of Avenue de Mayo. Plaza de Mayo, Boliva, and Catedral underground stations are all nearby.
