The Plaza de Mayo is, in many ways, the heart of Buenos Aires. It’s not only the city’s political and financial center but also the site of frequent political demonstrations.
The three main historic buildings on the plaza are the Cabildo (former seat of the Colonial government), government house (Casa Rosada), and the Buenos Aires Metropolitan Cathedral (Pope Francis’ former parish). At its center is the Pirámide de Mayo, a white obelisk built to mark the first anniversary of independence from Spain; it was the city’s first monument.
The plaza is almost always busy, filled with protestors, tourists, and locals going for a stroll.
